The NHBS Guide to Rockpooling

Rockpooling is an educational and extremely enjoyable wildlife activity that introduces you to a colourful world of creatures that are usually hidden beneath the sea. Rock pools are full of limpets, crabs, whelks, periwinkles and anemones, all of which have fascinating adaptations that allow them to live in this unique place. The intertidal zone is an exceptionally harsh habitat, with animals needing to cope with exposure to saltwater, rainwater, changing temperatures and sun. Rockpooling is a brilliant hands-on activity to introduce children to this unique habitat and discuss how animals and plants cope with living there.

Planning a Rockpooling trip

The best time to go rockpooling is in the late spring or summer, when the weather is milder and temperatures are warmer. There are many excellent locations to go rockpooling on the UK coast and, by searching the local area or consulting this list by The Wildlife Trusts, you can find some of the best spots. Once you know which area you are heading to, you need to consult the local tide table. Rockpooling is best done on a low spring tide, because the most interesting range of creatures are likely to be found nearest the sea edge. Pick a day with calm weather conditions and when the low tide point is at a suitable time in the day – you need to time your visit to be there for low tide and then watch carefully for the tide coming back in. Make sure that you take a sun hat, sun cream and wear sturdy shoes, as the rocks can be very slippery.

Bucket – a clear or white plastic bucket is great for storing your finds temporarily.

Net –a net can help with catching crabs when used carefully, but avoid scraping along rocks.

ID guide – there are a range of ID guides including laminated FSC sheets and seashore identification guides.

Pots – smaller animals can be transferred carefully to pots for a closer look.

Endoscope – peer deep into the depths of the rockpools and record images and videos with a handheld endoscope.

Approach rock pools carefully, as animals can be wary of noise and shadows appearing above them. Dip your bucket into the water to catch mobile animals or carefully search through with your hands. If you fill your bucket and pots with a little seawater then you can keep any creatures you find in there for a short period of time while you identify them. Watch out for crab claws as they can nip, and anemone tentacles as they can sting. Do not remove any creatures that are attached to the rocks as they may have a specific place that they attach to until the tide comes back in. Turn over stones to find crabs and have a good look to see if there is anything hiding in the seaweed. Once you have finished looking, make sure you return the animals gently back into the pool.

Gardening for Wildlife: Creating Habitat

In the first of our two-part series, Gardening for Wildlife: Providing Food, we looked at how to attract wildlife to your garden by including plants for pollinators and providing food for birds and mammals. In the second of our two-part ‘Gardening for Wildlife’ series, we look at how to create nesting or overwintering habitat effectively for the wildlife that visits your garden. Natural nesting sites for birds, insects and mammals have become rare in the broader landscape due to changes in farming, woodland management practices and building construction techniques. Wildlife-friendly gardens can provide fantastic habitat for invertebrates, birds, amphibians and mammals by making a few simple changes and by letting a bit of wildness back in.

Insects

It is easy to provide habitat for insects in your garden just by leaving the lawnmower in the shed. Setting aside a patch of grass to grow longer should encourage wildflowers to grow in your lawn, and will provide food and shelter for insects and small mammals. Creating a log pile in which beetles, woodlice and earwigs can shelter is also an easy way to increase garden wildlife habitat. You can provide additional nesting space for solitary bees or overwintering quarters for other insects by creating or installing an insect house. These can be homemade and constructed to your own design, or you can purchase purpose made houses. These are particularly important for solitary bees, who use tunnels in wood, mortar, plant stems or artificial houses to nest. They lay eggs and place a food source in a series of cells, and then block the entrance with materials such as mud, leaves or fine hair. Other nest sites can be provided by leaving dead wood and stems standing and leaving a patch of bare earth or mud bank for mining bees.

Bird Boxes

Providing bird boxes in your garden can be an excellent way of helping wildlife, as natural nest sites can be rare due to changes in house construction and woodland management techniques. There is a vast array of nest boxes available for many different species of birds, so it is worth knowing which bird species visit your garden before selecting a box. A good place to start is by providing a nest box with a 32mm entrance hole that is suitable for house sparrows or blue and great tits, who are enthusiastic occupiers of nest boxes. Most nest boxes are made of breathable materials such as wood or wood fibres mixed with concrete (Woodcrete or WoodStone). The advantage of Woodcrete and WoodStone nest boxes is that they are much more durable and can last for 10 years or more. Purpose-built nest boxes are available for many different species such as swifts, treecreepers and even robins. For more details on our most popular nest boxes, please see our series of blog posts on nest boxes suitable for different locations. For more details on where to hang your nest box, please see our blog post

Mammals

Gardens are extremely important for hedgehogs and can provide excellent opportunities for foraging and hibernation. Leaving a pile of fallen leaves or a log pile can give them a place to shelter during the daytime or you can choose to invest in a hedgehog nest box. These can provide a safe place for hedgehogs to sleep or hibernate – there is even the option of installing a nest box camera so that you can watch footage of them using the box.

Hedgehogs can travel up to 2km each night, eating as they go. Allowing them to move freely between gardens is important to ensure that they can obtain enough food and find safe spaces to sleep. If you have a garden fence, cut a hole at the bottom measuring 13 x 13cm to allow hedgehogs to pass through on their nightly wanderings. You could also remove a brick from the bottom of a wall or dig a channel underneath. 

Bats also use gardens for foraging, so increasing the number of invertebrates in your garden will help to attract them. Bats naturally roost in a variety of spaces including holes in trees. With natural cavities being rare, providing a bat box can be a great way of helping them and our series of blog posts on the top bat boxes for different locations, and our advice on where to hang your bat box is a great place to start. The best time to watch them is at dusk when you can sit in the garden and see them whizzing around catching mosquitoes. Alternatively, you can invest in a bat detector and identify the species visiting your garden. For both bats and hedgehogs, connectivity to other patches of suitable habitat is key. Hedgehogs use hedgerows or need access through fences to be able to visit multiple gardens, and bats use treelines and hedgerows when foraging.

Amphibians and Aquatic Invertebrates

The easiest way to help aquatic invertebrates and amphibians is by creating a pond or small body of water. Even if you have a small garden, you can create a mini pond with an old belfast sink or a washing up bowl. Choose a warm, sunny spot that will be good for dragonflies and tadpoles, consider planting a few native freshwater plants and wildlife such as pond skaters, damselflies and water beetles should soon find the spot. Please ensure that ponds are positioned with safety in mind if you have children, and that you include rocks or sloping edges so that wildlife can get in and out. There are fantastic guides to creating a pond available, such as the Wildlife Pond Book, and once your pond is up and running you can even try some pond dipping. It is not recommended to collect frogspawn from the wild, but you can encourage amphibians into your garden by providing damp areas such as log piles or a frog and toad house.

Watching Wildlife

Having attracted wildlife to your garden, there are several ways you can get fantastic views up close.  Binoculars give you a great view of wildlife that is further away, but with close focus distances now much improved, they also offer a great way of magnifying insects and aquatic invertebrates. Read our blog post to find out how to choose a pair of binoculars. Alternatively, trail cameras can be used very effectively in gardens to record garden visitors such as hedgehogs and birds. These standalone weatherproof cameras use passive infrared to detect passing warm-bodied animals and take either still photographs or videos. For more information on trail cameras, see our blog post on how to choose a trail camera. For a really close-up insight into what the wildlife in your garden is doing, consider installing a nest box camera. See our guide on how to choose a nest box camera for advice on the different options. A hedgehog nest box camera can also give you really amazing footage of hedgehogs feeding and nesting.

By providing food resources and suitable habitat for wildlife, you can ensure that your garden becomes a sanctuary for the animals around you and a spectacle of nature right on your doorstep.

The NHBS Guide to UK Corvid Identification

There are eight species of corvid in the UK, five of which belong to the Corvus genus. They are intelligent birds, with many studies finding species demonstrating self-awareness and tool-making abilities. Their brain-to-body mass ratio is only slightly lower than ours and equal to cetaceans and non-human great apes.

Corvids occur worldwide, except for the polar ice caps and the southern tip of South America. Certain species are a common sight in our urban areas, having adapted to the proximity of humans. Some surveys have even found that fitness and reproduction have increased due to human development. Crows and ravens have been shown to have high reproduction rates and a positive association between annual survival and proximity to human development.

The crow family feature heavily in mythology and folklore, often as omens of ill fortune or death, though magpies can also be considered a herald of fortune. This is thought to have derived from their scavenging behaviour, feeding on carrion at battlefields. They were considered by some to be ‘soul guides’, there to carry to dead into the afterlife. Ravens feature in Scandinavian mythology, as the god Odin had two ravens that would tell him secrets they’d heard. This communication also features in Anglo-Saxon history. This is most likely due to the ability of many corvid species to mimic sounds in their environment, including human speech. They do this by using their two ‘syrinxes’, vocal organs located at the base of the bird’s trachea, which is made of ossified cartilage, muscles and vibrating membranes. As corvids have excellent memories, they can be taught a wide range of words and sentences.

All species are listed as green by the Birds of Conservation Concern 4, with the Eurasian Jay being upgraded from its previous amber status.

Carrion crow (Corvus corone)

Distribution: Common and widespread, although less common in northwest Scotland. They are found across many habitats, including woodland, farmland, heathland and urban areas.
Wingspan:  84–100cm
What to look for: An all-black species, they have a shiny, thick black beak that is of medium length, and black legs. Their black plumage has a glossy sheen. They are fairly solitary and are most likely seen alone or in pairs, but they can occasionally form flocks.

Jackdaw (Corvus monedula)

Distribution: Common and widespread, except for parts of the Scottish Highlands.
Wingspan: 64–73cm
What to look for: The jackdaw is a black species with a distinctive silvery patch on the back of its head. It has pale eyes that are quite easy to see. Their beaks are shorter than carrion crows, though both have an extended patch of feathers on the top of their beak.

Jackdaw by hedera.baltica via Flickr
Rook (Corvus frugilegus)

Distribution: Widely distributed across most of the UK, although less widespread in Scotland and mostly absent from far northwest Scotland. They are mostly seen in open fields but can be found along roadsides and occasionally in parks and villages. They mainly avoid the centre of larger towns and cities.
Wingspan: 81–99cm
What to look for: This species is black, with a distinctive bare, greyish-white face and a peaked head. Rooks also have a thinner, paler beak than other corvids, such as carrion crows. This beak darkens towards the tip. Juveniles do not have a bare face, therefore can resemble other all-black corvids such as crows, but they can be distinguished by their peaked head.

Rook by hedera.baltica via Flickr
Jay (Garrulus glandarius)

Distribution: Widespread across England, Wales and Northern Ireland, present in parts of Scotland except in the north.
Wingspan: 52–58cm
What to look for: This colourful bird is a light brown to pinkish-grey, with a pale throat and prominent black moustache stripes. Their forehead and crown are pale with dark stripes. The upper surface of their wings is white and black, with a distinctive bright blue patch patterned with black bars. Their tail is white or pinkish underneath but their upper tail feathers are mainly black.

Jay by Airwolfhound via Flickr
Magpie (Pica pica)

Distribution: Widespread across the UK, except the highlands.
Wingspan: 52–62 cm
What to look for: This species has a distinctive black and white plumage, with a purple-blue shine to the wings and a green shine to the tail. They have a black beak, black legs and black leg feathers.
Did you know? Magpies have long been associated with folklore in many countries, with a wide range of beliefs. Magpies have been thought to signal death, bad luck, good luck, fortune-telling and happiness. They are also the centre of the well-known ‘one for sorrow’ nursery rhyme where the number of magpies signals different events and occurrences. Depending on the version, gatherings of magpies can signal a birth, funeral, wedding, gold, silver, the gender of a child and even the devil.

Magpie by Airwolfhound via Flickr
Raven (Corvus corax)

Distribution: Widespread across Wales, Northern Ireland and the West of Scotland and England. They are found across a number of habitats, including woodland, farmland, upland and marine habitats.
Wingspan: 115–150cm
What to look for: This is the largest member of the crow family, with an all-black plumage, a large bill and long wings. Their necks are thick, with a shaggy appearance. They have a diamond-shaped tail, best seen in flight. They closely resemble the carrion crow, except for their much larger size, but they can resemble raptors such as buzzards in flight.

Raven by Imran Shah via Flickr
(Red-billed) Chough (Pyrrhocorax pyrrhocorax)

Distribution: Small, isolated populations along the west coasts of Wales, Cornwall and Ireland, as well as the Isle of Man.
Wingspan: 73–90cm
What to look for: Choughs have a blue-black plumage with a green sheen to their wings and tail. They have a slender, red bill that curves downward. Its legs are red with black claws. Juveniles have an orange bill and either pink or grey legs.
Did you know? In 2002, a pair of choughs raised young in Cornwall for the first time in more than 50 years. They continued to nest successfully for over a decade, raising 46 chicks in total. In 2022, the population reached 200 birds, with 25 pairs successfully raising over 70 young.

Red-billed chough by gailhampshire via Flickr
Hooded crow (Corvus cornix)

Distribution: Present in Northern Ireland, north and west Scotland, and the Isle of Man. In winter, it is present on the eastern side of England.
Wingspan: 93–104cm
What to look for: This species has an ashy-grey plumage, with a black head, throat, tail, wings and thigh feathers. It has a black beak and legs, with dark brown eyes.
Did you know? The hooded crow was thought to be the same species as the carrion crow until 2002 when they were given full species status.

The NHBS Guide to UK Thrush Identification

Thrushes are passerines in the family Turdidae. They are found worldwide. The family was once much larger before biologists determined that the former subfamily Saxicolinae (chats) were Old World flycatchers rather than thrushes. Some thrushes are permanently resident in warm climates, while others migrate to higher latitudes during summer, often over considerable distances. There are four species that regularly breed in UK as well as two winter visitors that also occasionally breed here.

These small to medium-sized ground living birds feed on mainly on insects, other invertebrates and fruit. They generally inhabit wooded areas, creating cup-shaped nests that are sometimes lined with mud. They lay between two to five speckled eggs, with two or more clutches a year.

All the thrushes listed below are protected under the Wildlife and Countryside Act 1981, including their eggs and nest sites, with several included on the UK Red or Amber List. Song thrushes have even been designation as a Priority Species under the UK Post-2010 Biodiversity Framework.

Blackbird (Turdus merula)

Distribution: This is the most common and widespread thrush, present all year round.
BoCC5 status: Green
Wingspan: 34–38cm
What to look for: Males and females look different, with males being all black, with bright yellow eye-rings and beaks, while females are a redish-brown, with a speckled appearance and duller yellow eye-rings and beaks. The female’s beak can also be dark brown.

Male blackbird by Jacob Spinks via Flickr
Female blackbird by Jacob Spinks via Flickr
Fieldfare (Turdus pilaris)

Distribution: These are winter birds, with only a few remaining to breed in the UK all year round.
BoCC5 status: Red
Wingspan: 39–42cm
What to look for: This is a slight larger bird, with grey heads, necks and rumps, though they have a dark strip across their eye to their orange and black beak. Their backs are dark brown and their tails are black, with a tinged orange throat and a paler, puff coloured breast. They are speckled with dark markings, which are larger on their breast. Their underside is pale.

Fieldfare by hedera.baltica via Flickr
Mistle Thrush (Turdus viscivorus)

Distribution: Widespread, across the whole of the British Isles throughout the year. They are absent in parts of the northern and western isles of Scotland.
BoCC5 status: Red
Wingspan: 42–48cm
What to look for: This is the largest of the thrushes, with a dark brown back and paler underside and throat that is speckled with dark brown. It has a pale eye-ring, cheeks and lores. They stand quite upright and have orange legs and an orange and dark brown beak.

Mistle Thrush by ianpreston via Flickr
Redwing (Turdus iliacus)

Distribution: This is a winter visitor, arriving from late September onwards and leaving again in the summer. They’re found across the UK, except for parts of North Scotland.
BoCC5 status: Amber
Wingspan: 33–35cm
What to look for: This species is the smallest thrush that regularly visits the UK, similar in appearance to the song thrush. Their distinctive feature, however, is the bright orange-red patch on their sides under each wing, as well as the pale stripe over their eye.

Redwing by Alison Day via Flickr
Ring Ouzel (Turdus torquatus)

Distribution: Summer visitors are found in the uplands of Scotland and northern England, as well as parts of north west Wales and Dartmoor. During spring and autumn, when they migrate, they may be spotted along the east and south coasts of the UK.
BoCC5 status: Red
Wingspan: 38–42cm
What to look for: Males are black, with a pale panel on their wings and a bright white band across their breast, resembling a bib. Females are similar but their colouration is much less striking, looking like a ‘washed out’ version of the male. Both have an orange and black beak and black legs. Their wings and underside feathers have pale outlines, and some can have white patches on their heads.

Male ring ouzel by Nick Goodrum via Flickr
Female ring ouzel by Stefan Berndtsson via Flickr
Song Thrush (Turdus philomelos)

Distribution: Found across the UK, through missing from parts of Northern and Southern Scotland.
BoCC5 status: Amber
Wingspan: 33–36cm
What to look for: This, other than the blackbird, is probably the most well known member of the thrush family. They are a small bird, browner than the mistle thrush, with smaller speckles. Their sides and cheeks are yellowish, with a paler underside, eye-ring, undertail and legs. Their beaks are yellow and black.
Did you know? The male song thrush copies other birds’ songs, creating a repertoire that it sings on repeat, often to reinforce territories and attract mates.

The NHBS Guide to UK Rails

Rails, from the family Rallidae, are small- to medium-sized birds and include crakes, coots and gallinules. They can be found in most terrestrial habitats, but the most common are marshland and dense forests. They are present on every continent except Antarctica and are generally omnivores, consuming invertebrates, fruits and seedlings. Typically, they prefer dense vegetation near bodies of water, such as lakes, rivers or swamps.

This is a large family with around 130 species. We have several resident species in the UK, as well as a number of migrants and occasional visitors. Identification of rail species relies on plumage, leg and frontal shield colouration (if present), and their calls. Binoculars and scopes are useful for spotting these features from a distance. Juveniles and chicks will often differ in appearance from adults, therefore a guide covering these life stages is also helpful.

How are rails faring?

Due to hunting, egg collection and habitat loss, many rail species have become extinct and others are endangered. The corncrake and the spotted crake, for example, are classified as Red and Amber under the Birds of Conservation Concern 4. Due to their general flightlessness, they are often heavily impacted by introduced species such as domestic cats. American mink, a nonnative and invasive species in the UK, are a particular threat to moorhen as they can be a main prey item.

Corncrakes are the focus of several conservation projects due to their Europe-wide population declines. Research has shown that increasing the areas of suitable tall vegetation, particularly in spring, autumn and mid-winter, delaying mowing and using certain mowing methods can be effective conservation measures. Up to 60% of chicks are killed by standard mowing practices, due to their flightlessness and reluctance to escape to areas already cut. Since 1992, conservation measures have been implemented on a large scale and have resulted in a partial recovery, from 480 calling males in 1993 in the UK to 1,284 in 2014. However, since 2014, numbers are declining again in Scotland, down by 30% to 870 males in 2019.

Eurasian Coot (Fulica atra)

Distribution: Widespread in England and Wales, rarer in Scotland and Ireland. Numbers are boosted by migrants during winter.
BoCC4 status: Green
Wingspan: 70–80cm
What to look for: The coot is an all-black bird with a distinctive white bill and ‘shield’ on its forehead. They have yellow and white legs with large white feet that have lobed flaps of skin, which act similarly to webbed feet to aid their swimming.

Eurasian coot by Dave Morton via Flickr

Moorhen (Gallinula chloropus)

Distribution: Widespread in England, Wales, and Ireland, but less common in Scotland.
BoCC4 status: Amber
Wingspan: 50–55cm
What to look for: Moorhens have a similar appearance to the Eurasian coot, with a blackish plumage, which, when viewed close up, is actually dark brown on its back and wings with a bluer underside. However, they have a red and yellow bill, long green legs and white stripes on their flanks

Moorhen by cuatrok77 via Flickr

Corncrake (Crex crex)

Distribution: Scarce summer breeding population, recorded in the Western Isles, coastal parts of northern Scotland, parts of Ireland and a few key areas in England.
BoCC4 status: Red
Wingspan: 46–53cm
What to look for: Corncrakes are small birds, slightly larger than a blackbird, with chestnut and dark brown wings and back, a mottled grey to buff underside and reddish-brown and white flanks. Its head is grey, with chestnut eyestripes and a chestnut and dark brown crown. Its legs and bill are pale pink.

Corncrake by Jo Garbutt via Flickr

Spotted Crake (Porzana porzana)

Distribution: Scarce, scattered pairs across Scotland and England.
BoCC4 status: Amber
Wingspan: 37–42cm
What to look for: The spotted crake is similar to the corncrake, with chestnut and dark brown wings and back and a greyer underside, but this species is speckled with white throughout and has a buff undertail. It has a similar grey head, chestnut and dark brown crown and chestnut eyestripe. Its legs are yellowish-green and its bill is a mix of orange, yellow and grey.

Spotted crake by Imran Shah via Flickr

Water Rail (Rallus aquaticus)

Distribution: Widespread but thinly distributed throughout England, parts of Wales and Ireland. More scarce in Scotland and absent from upland areas.
BoCC4 status: Green
Wingspan: 38–45cm
What to look for: Their back and wings are chestnut and dark brown, with a grey underside and face. They have black-and-white barred flanks, a chestnut and dark brown crown, a long, red bill with a darker upper part and greyish-pink legs.

Sora (Porzana carolina)

Distribution: Occasional visitors, small number of records around England.
Global status: Least concern
Wingspan: 38cm
What to look for: The sora has a brown back marked with small black and white lines, a blue-grey underside and face, a short yellow bill with black markings at the base and yellow legs. Their flanks are barred with white and black.

Trail Cameras: A Comparison

Trail cameras are an invaluable piece of equipment for those seeking to monitor wildlife as it is when there are no humans around. Unlike typical cameras, trail cameras are designed to be left in a particular location to capture photographs or video footage of passing animals. Thanks to infrared imaging technology, most modern trail cameras will also allow you to capture images of nocturnal animals under low light conditions.

The best trail cameras can endure a range of tough weather conditions and extreme temperatures due to weatherproof casing and a robust design. Their small size and camouflaged casing allow these cameras to blend into their surroundings and remain relatively inconspicuous. Most trail cameras can also be fitted with a python lock or security box to protect against damage or theft.

At NHBS, we sell a wide range of trail cameras and, like all products, there are advantages and disadvantages depending on the model and brand. To compare the trail cameras in our range we have prepared categories based on several of the key factors to consider when buying a trail camera. All recommendations found here are our opinions and views may differ on which cameras are best for each category.

Beginner Camera 

Browning Strike Force Pro X 1080

With a fast trigger speed, strong picture quality and robust design the Browning Strike Force Pro X 1080 performs well across all major categories. While not quite reaching to heights of some of our more advanced cameras in terms of picture quality, this economic camera is perfect for those looking for a starter camera or for high quality at an affordable price.

Picture Quality

When considering image quality, keep in mind that manufacturers sometimes inflate megapixel ratings through interpolation, a process by which pixels are digitally added to the image. While on paper photos have a higher megapixel count, the image quality is not improved. This is a marketing gimmick which eats up storage and generates longer recovery times.

While our top picks for picture quality both use interpolation, it is the quality of the photographs and footage produced by the camera which we base our opinion on.

Browning Recon Force Elite HP5

With crisp and clear daytime pictures and excellent night-time imagery, the Browning Recon Force Elite HP5 wins the top spot for picture quality. Video footage produced by this camera is of equally high quality as shown by recordings from our own team:

This camera is significantly cheaper than its close competitor, the Bushnell Core DS-4K. Another factor in this camera’s favour.  

Bushnell Core DS-4K 

A closer runner up, the Bushnell Core DS-4K likewise demonstrates superb picture quality. An advantage of this camera is the longer battery life when using the video capture setting, permitting longer deployment in the field, together with a world-beating 4K video resolution.  

Night Footage 

The nighttime capabilities of modern trail cameras are a key draw for many users. Using infrared technology, most trail cameras can capture photographs and videos of elusive nocturnal animals whose movements are normally challenging to monitor. 

Browning Spec Ops Elite HP5 

While the Browning Recon Force Elite HP5 and the Bushnell Core DS-4K perform well at night, if you are looking for a trail camera specifically designed to excel in low light conditions, the Browning Spec Ops Elite HP5 is a safe bet. This camera displays superb nighttime video and photographs with excellent clarity and contrast. A stealthy camera with top of the range trigger and recovery speeds, the Spec Ops Elite HP5 benefits from a no glow IR flash which allows it to remain inconspicuous in the presence of easily startled nocturnal animals.  

Browning Dark Ops Pro DCL 

Equipped with Radiant 6 Night Illumination Technology and a longer flash range than the Spec Ops Elite HP5, the Browning Dark Ops Pro DCL produces outstanding nighttime footage; the trade-off is a significantly reduced battery life and inferior daytime picture quality compared to the Spec Ops. 

Trigger Speed 

The trigger speed is the amount of time between the camera detecting movement and a photograph being taken. For those looking to monitor larger animals a quick trigger speed is of secondary importance; however, trigger speed is very important when monitoring small fast-moving animals where a small difference in trigger speed might mean the difference between capturing a picture of the animal or not. 

Browning Spec Ops Elite HP5 

Here the Spec Ops Elite HP5 stands out from the crowd yet again. One of the top cameras in our range, its lightning-fast trigger speed of 0.1 seconds makes this camera a perfect choice for those monitoring even the quickest creatures. The Spec Ops Elite HP5 also boasts a swift recovery speed of 0.5 seconds, granting the ability to rapidly capture multiple pictures of an animal in the camera’s detection range.   

Battery Life 

Browning Patriot   

The Browning Patriot is not only one of our best all-rounders, performing well in all categories, but also the camera in our range with the longest battery life. Depending on the settings used (videos use up more battery power), this camera can last for over a year in the field without changing batteries.  

Browning Strike Force HD Pro X 

Another well-rounded camera, the Strike Force is also a strong performer when it comes to battery life. 

Durability 

Durability – Reconyx HyperFire 2 HF2X 

A strong favourite amongst researchers operating in extreme environments, the Reconyx HyperFire 2 HF2X offers unparalleled resilience and longevity. We tend to recommend this camera for use in tough conditions as it can operate in temperatures of -29° to +50°C and comes with an impressive 5-year warranty. The more expensive Reconyx UltraFire XR6 has the benefit of improved picture quality; however, this trail camera carries a shorter 2-year warranty and slower trigger speed.

Cellular and Solar Cameras 

Needing to go out to your trail camera when you want to change batteries, check photos or change settings can be time consuming, especially if your camera is in a remote location or if you have multiple cameras set up in different areas. Cellular and solar functionality save valuable time by reducing the frequency with which you need to physically interact with your trail camera. The trade-off is reduced image quality when compared to cameras without these features in a comparable price range. 

Cellular – Spypoint LINK-MICRO-LTE 

The Spypoint LINK-MICRO-LTE enables remote access to photos and settings by utilising cellular networks. It comes with a pre-activated SIM card, the free Spypoint app and a free monthly data plan allowing you to transfer up to 100 images per month. If you need to transfer more photos, choose from Spypoint’s affordable monthly payment plans. 

While excellent for those wishing to leave their trail cameras in remote locations, remember the cellular features of the camera require a network connection to function, so ensure that you place the camera in a location with signal. 

Please note, we cannot guarantee that cellular functions of the link series cameras will work outside of the UK 

Solar – Num’axes PIE1060 Solar Wi-Fi Trail Camera   

The Num’axes PIE1060 Solar Wi-Fi Trail Camera comes with a compact solar panel attached to the top of the unit which provides the camera’s lithium battery with an indefinite power supply when placed in sufficient sunlight. This negates the need to regularly replace the trail camera’s batteries, saving valuable time. The Num’axes camera likewise features WiFi technology, allowing photos to be remotely downloaded when inside the camera’s WiFi signal range.  

Cellular and Solar – Spypoint LINK-MICRO-S 

You can even combine features with the Spypoint LINK-MICRO-S. The built-in solar panel and cellular function allows you to leave the trail camera in the field for longer periods of time with minimal physical interaction.  

Please note, we cannot guarantee that cellular functions of the link series cameras will work outside of the UK. 

Recommendations and Accessories 

A few important tips and accessories can go a long way to getting the best experience out of using your trail camera. 

Use lithium batteries 

Many new users elect to use alkaline or standard rechargeable batteries in their trail cameras and find that their camera is not working as expected. Lithium batteries are capable of giving off a stronger surge of energy. Most trail cameras are therefore designed to be used with lithium batteries; accordingly, we offer a bundle when purchasing a trail camera which normally includes eight lithium batteries. Using the wrong type of batteries is among the most common reasons for why a trail camera is not functioning correctly. 

Rechargeable alternatives are available which perform well with trail cameras. 

Python Mini Cable Lock 

The versatile Python Lock with an 8mm diameter and length of 180cm is ideal for securing equipment and can be used with almost all our trail cameras.  

Security Boxes 

These tough and sturdy security boxes will help protect your trail camera from theft and damage. Double check that the security box you are purchasing is compatible with your trail camera model.

The NHBS Guide to UK Lichens

Lichens are composites of two or more different organisms, an alga or cyanobacteria living among the filaments of a fungus species. It is a symbiotic relationship where the fungal partner, also termed the mycobiont, makes up the body or ‘thallus’, and the algae or cyanobacteria is the photosynthetic partner, or photobiont, providing nourishment. There is debate as to whether this symbiotic relationship is mutualistic, where both parties benefit and neither is harmed through this interaction, or a type of controlled parasitism, where the mycobiont is ‘farming’ the photobiont for the sugars produced by photosynthesis.

There are over 1,800 species recorded in the UK, and 17,000 species worldwide. There are three main categories of lichen body types: crustose, fruticose and foliose. Crustose lichen are species that form thin, crust-like coverings that are tightly bound to the surface they’re on. Fruticose lichen form coral-like bushy or shrubby structures with a holdfast, a root-like structure that anchors it to trees, rocks or other surfaces. Foliose lichen are species that have a flattened, leaf-like thallus with an upper and lower cortex, the surface layer or ‘skin’ of the lichen, and attach to surfaces by hyphae with root-like structures called rhizines. There are other growth forms, such as leprose (a powder-like or granular appearance), squamulose (scaly), filamentose (stringy) and byssoid (wispy). These can also be divided into numerous subtypes.

Lichens are an important food source for many species, such as deer and goats, and are used as building material for birds nests. They occur from sea level to high elevations, tolerating many different environmental conditions. They grow on a wide variety of surfaces, from tree bark, leaves, mosses, rocks, gravestones, roofs, soil, bones and rubber. The general guidance for identifying lichens is to look at growth form, colour, habitat and substrate type and distribution. You should also look for the presence or absence of certain structures such as rhizines, soredia (scale-like reproductive structures), isidia (column-like outgrowths of the thallus) and apothecia (a cup-shaped structure containing asci, spore-bearing cells). A hand lens and a guide that covers other lichen species will be useful for identifying these.

Spot tests can be performed, which involve placing a drop of a chemical, such as potassium hydroxide or sodium hypochlorite, on different parts of the lichen. Any colour change, or lack thereof, can be used for identification when following dichotomous keys for lichen species. Care should be taken when using chemicals, however, particularly in the natural environment, due to the damage they can cause.

Some species are harder to identify in the field and require microscopic examination or further chemical testing. Additionally, there may be variations in appearance due to weather conditions or the condition of the lichen. Its colour can change when the lichen is wet or in poor condition, for example, or the growth form can appear different if the lichen has begun to disintegrate.

Elegant Sunburst Lichen (Xanthoria elegans)

Distribution: Widespread, but most frequently found in upland areas.
Growth type: Foliose
What to look for: This is a small lichen, typically no more than 5cm wide with lobes that are less than 2mm broad and closely pressed against a surface. Their upper surface is orange, with a white lower surface, a cortex (skin), and attached with short, sparse hapters (peg-like structures on the lower surface of lichen). Soredia and isidia are absent but apothecia structures are common.

Common Greenshield Lichen (Flavoparmelia caperata)

Distribution: Widespread, more common in the western and southern parts of England, scarce in northern and central Scotland.
Growth type: Foliose
What to look for: This is a pale grey species that turns yellowish-green when wet. The lower surface is black with a brown margin and black, unbranched rhizoids that attach it to the substrate. Its lobes are rounded, around 3–8mm wide, with patches of soredia. The lobes are often wrinkled in appearance, particularly in older specimens.

Hooded Rosette Lichen (Physcia adscendens)

Distribution: Widespread
Growth type: Foliose
What to look for: Hooded rosette lichen is a pale grey species, with lobes up to 2mm wide that are curled into a hood shape. They have cilia, thin projections from the margin of the lichen, which progress from pale to black at the ends. Soralia are usually abundant and disc-shaped apothecia can also be present. The lower surface is white to greyish. They are attached to surfaces by rhizines, which can be white to black.

Hoary Rosette Lichen (Physcia aipolia)

Distribution: Fairly widespread
Growth type: Foliose
What to look for: This species is pale, from white to bluish-grey. It has white-rimmed apothecia that have black centres. Soralia and marginal cilia are absent. The lobes also have distinct flecks of white called pseudocyphellae. It grows in well-lit habitats, usually on fences or trees, often in the nodes of branches.

Common Orange Lichen / Yellow Scale (Xanthoria parietina)

Distribution: Widespread
Growth type: Foliose
What to look for: This species is a yellow-orange coloured lichen that can appear greener when wet. It is a leafy lichen with flattened lobes that are between 1–4mm in diameter. Its lower surface is white and has pale rhizines or hapters. Similarly to X. elegans, soredia and isidia are absent but yellow or orange apothecia are usually present. There is a cortex that is made of tightly packed fungal hyphae, which can be thicker in more exposed locations and is thought to protect the lichen from evaporation and exposure.

Monk’s Hood Lichen (Hypogymnia physodes)

Distribution: Widespread
Growth type: Foliose
What to look for: The thallus is grey to greenish-grey, with inflated lobes that lift at the tips. These inflations can burst open, displaying the floury soredia inside. They may have black dots, called pycnidia, near the lobe tips. Rhizines are absent and the lower surface is wrinkled with a light brown margin, darkening towards a black centre. They may have apothecia, which occur on short stalks and have a red-brown disc.

Many-forked Cladonia (Cladonia furcata)

Distribution: Widespread, particularly in heathland, healthy turf and on dunes.
Growth type: Fruticose
What to look for: This species has an upright secondary thallus, called the podetium, which can vary from grey-green to brown. This forms loose mats, and the finer branches are erect and sharply pointed. Soredia are absent, with few to no squamules (scales). They may have small, green areolar patches set into or raised on the cortex surface. The podetia become darker brown and glossy with age. Pycnidia, the asexual fruiting bodies, are small, brown and are found on the branch tips. This species has apothecia, which are brown and occur in extended clusters at the ends of podetia.

Lasallia pustulata

Distribution: Scattered distribution, mainly in parts of Wales, south- and north-west England and scattered areas of Scotland.
Growth type: Foliose
What to look for: The thallus of this species is a pale grey or brown when dry but becomes brownish or yellowish-green when wet. It has convex pustules across its upper surface which often appear darker in colour and are covered in a powder towards the centre. The margins of this species are often ragged and can be darkened by the presence of black isidia. The lower surface can be grey, brown or black, and have corresponding depressions to the pustules on the upper surface. Rhizines are absent and this species is attached to substrate by a stalk.

Wet state: Björn S… via Flickr

Oakmoss (Evernia prunastri)

Distribution: Widespread
Growth type: Fruticose
What to look for: They primarily grow on oak trees but can be found on the trunk and branches of other deciduous trees and conifers. This species is flat and strap-like, highly branched (forked) and bushy, forming large clumps when growing together. When dry the thallus is rough and the colour can vary from green to a pale greenish-white. When wet, they appear dark olive-green to yellow-green and are rubbery in texture.

Pink Earth Lichen (Dibaeis baeomyces)

Distribution: Widespread in Scotland and Wales, scattered throughout England, more common in the north and west.
Growth type: Fruticose
What to look for: Pink earth lichen have bulbous pink apothecia that are around 1–4mm in diameter, set on stalks up to 6mm tall, although these are not always present. The thallus can vary in colour between grey or white, occasionally with a pink tinge, and can appear greenish-grey when wet. They are coarsely granular and are sometimes covered in small, white balls up to 1mm in width, with small powdery areas.

The NHBS Guide to UK Mosses

Mosses belong to a group of plants called bryophytes. Comprising the mosses, liverworts and hornworts, there are over 1000 species of bryophyte in Britain and Ireland, which is around 58% of the species found in the whole of Europe.

Although often overlooked, mosses are fascinating to study and are structurally both complex and elegant. When seen through a hand lens or microscope they have details that easily compare in beauty with those of their larger plant cousins.

In this article we’ll introduce you to a handful of some of the commonest and easiest to identify mosses that you will find in the UK. If you’re interested in learning more, we’ve also provided a list of excellent field guides and books at the bottom of the guide, along with some helpful links to other online resources.

Why are mosses important?

Mosses are one of the first plants to colonise bare ground. They provide important habitat for invertebrates, particularly those fond of a damp environment such as slugs and woodlice. A healthy mossy environment will also be attractive to larger animals who feed on these invertebrates, such as frogs and toads, and will provide shelter to a diverse range of microscopic organisms, including nemotodes, rotifers and tardigrades.

Mosses can hold a huge amount of water and so play a crucial role in mitigating flooding during periods of intense rainfall. Sphagnum moss in particular can absorb up to 20 times its weight in water, and is instrumental in slowing the flow of rainwater from the hills and moors and reducing the risk of flooding in downstream towns and cities.

Did you know?
  • Mosses have stems and leaves but no true roots or advanced vascular systems. This is why we only have small mosses and not ones that are the size of trees!
  • There are around 20,000 species of moss worldwide and they are found everywhere except for in the sea – even in Antarctica!
  • Unlike flowering plants, mosses produce spores rather than seeds and flowers. Spores are produced in a small capsule which grows on a long stem called a seta.
  • Mosses require damp conditions for reproduction – this is because the male cells require a film of water in order to reach the female cells and fertilise them.
Common UK mosses

Rough-stalked feather moss (Brachythecium rutabulum)

Brachythecium rutabulum. Image via Wikipedia Commons.

Also known as ‘ordinary moss’, rough-stalked feather moss is one of our most common moss species, and can be found growing widely in woodlands, lawns and at the base of hedges. It is yellow-green in colour and has branching stems with pointed oval leaves. Shoot tips are generally pale and glossy. Curved, egg-shaped capsules are frequently produced.

Common haircap (Polytrichum commune)

Polytrichum commune. Image via Wikimedia Commons.

Also known as marsh hair moss, common haircap is one of our tallest species of moss and can form clumps up to 40cm in height. Found in damp, acidic areas such as heaths, bogs and moorland, it can also be found near to streams and rivers within woodland. Plants are bright green, fading to brown with age, and often grow in compact clumps. The stems are tough and wiry, and its leaves are narrow and spear-shaped. When viewed from above, each individual stem looks star-like. In the summer it produces brown, box-shaped capsules.

Swan’s-neck thyme-moss (Mnium hornum)

Mnium hornum. Image via Wikimedia Commons.

Swan’s-neck thyme-moss is abundant in acidic woodland on logs, rocks and soil. It has upright stems which are 2–4cm tall, and leaves which are approximately 4mm in length with a toothed border. Frequently produces capsules on the end of 2.5–5cm long stalks. Capsules have a pointed tip.

Common tamarisk moss (Thuidium tamariscinum)

Thuidium tamariscinum. Image via Wikimedia Commons.

Common tamarisk moss is very distinctive and forms loose mats of fern-like shoots which range from yellow-green to dark green. Individual leaves are triangular or heart shaped, and the stems can be green or red-brown. It forms capsules only occasionally in the autumn and winter. It commonly grows on neutral soil in woodland, hedges and damp grass.

Sphagnum moss (Sphagnum spp.)

Sphagnum capillifolium. Image via Wikimedia Commons.

There are more than 30 species of sphagnum moss in the UK and they can be very difficult to tell apart. Although each plant is small, they often grow together in dense mats to form large areas of spongy carpet. Sometimes referred to as ‘bog-mosses’, they can be beautifully multi-coloured and thrive on peat bogs, marshland, heath and moorland. They also have an important role in the formation of peat bogs.

Common striated feather-moss (Eurhynchium striatum)

Eurhynchium striatum. Image via Wikimedia Commons.

Common striated feather-moss is common in lowland woodland, particularly those with a high clay soil. It often forms cushions or mats that can cover large areas. Leaves are triangular or heart-shaped with finely toothed margins and have wrinkles that run down the length of the leaf (you may need a hand lens to observe this identifying feature). Spore capsules are only occasionally present, but have a beak-shaped tip.

White-clawed crayfish in the UK

The UK is home to a single native species of crayfish – the white-clawed crayfish Austropotamobius pallipes. This attractive freshwater crustacean has a bronze-coloured body and white-undersides to its claws, for which it is named. They require clean freshwater habitats such as streams, rivers and lakes where they can rest under stones and rocks during the day and then spend the night foraging for food. Their diet is omnivorous and they feed on a range of foods including plants, carrion and invertebrates. They will also eat other white-clawed crayfish when the opportunity arises!

Threats to native UK crayfish

The white-clawed crayfish was once widespread and common throughout England and Wales, but since the 1970s populations have declined by 50–80%. Without intervention it is expected that they will become extinct over the next 20 years. Their decline is in large part due to the introduction of the North American signal crayfish which outcompetes the native crayfish for food and habitat. The signal crayfish also carries ‘crayfish plague’, a fungal disease that the white-clawed crayfish has no natural resistance to. Declining water quality and loss of suitable freshwater habitats have also contributed to their decline.

How are crayfish protected in the UK?

White-clawed crayfish are fully protected under the Wildlife and Countryside Act 1981 and The Conservation of Habitats and Species Regulations (2017). As a result, it is an offence to kill, injure or disturb them and their habitat cannot be destroyed or damaged. Any development which will, or is likely to, impact white-clawed crayfish and their habitat will only be allowed if it provides a net benefit to the crayfish through a combination of mitigation, compensation and enhancement strategies. This may involve habitat restoration projects or the modification of existing freshwater areas to make them more suitable for crayfish to survive and thrive.

When and how are crayfish surveyed?

Crayfish surveys are required if a development is being planned in an area that currently supports, or has the potential to support, white-clawed crayfish. They can be surveyed using a variety of methods including relatively new eDNA technology, which analyses water samples to detect the presence of DNA specific to the white-clawed crayfish. eDNA studies, however, cannot provide information on population size and so follow-up surveys are usually required should eDNA be detected. Most commonly crayfish are surveyed by manually searching likely refuges. If this isn’t possible due to access issues or water depth then crayfish traps can be deployed. These traps are of the live-catch variety – trapped individuals are returned to the water unharmed once they have been recorded.

What else is being done to conserve the white-clawed crayfish?

As well as being afforded a high level of protection in UK legislation, there are a number of conservation projects which aim to conserve or bolster existing populations of white-clawed crayfish. As part of the South West Crayfish Project, Bristol Zoo are breeding white-clawed crayfish in captivity which can be used to boost existing populations or establish new ones. They are also valuable in educating zoo visitors about their plight.

Control of introduced crayfish is also being carried out in certain areas through trapping or the use of biocides. Similarly, the control of plague and other crayfish diseases is of paramount importance. All waterway users should be aware of how easily plague spores are carried between sites and make all reasonable efforts to stop it spreading via their clothes and equipment.

A Summer of Dragonflies

Seeing dragonflies swoop over water is a quintessential sign that summer is upon us. When in flight their movements are mesmerising – using their two sets of wings either in synchrony or beating separately, they are able to fly in any direction they choose, altering their speed and movement instantly in mid-flight to create a dance that is unlike any other organism. But while the flying adults are frequently seen during the warmer months, many of us know very little about their life during the rest of the year.

In this article we will take a look at the dragonfly life cycle, explore how climate change and other threats are affecting dragonfly populations globally, and offer some tips on how to attract dragonflies to your garden.

Dragonfly life history

Dragonflies belong to the order Odonata within the sub-order Anisoptera (meaning ‘unequal-winged’). This order is also home to the closely-related damselflies (sub-order Zygoptera). Although at first glance dragonflies and damselflies appear similar, dragonflies are usually larger and bulkier with significantly larger eyes when compared to the slightly built and rather delicate damsels. When at rest dragonflies hold their wings open whereas damsels keep theirs closed, next to the body.

There are three distinct phases in the dragonfly life cycle: egg, nymph (larva) and adult.

Dragonflies breed in or on water bodies such as marshes, swamps, ponds, pools and rivers; after mating the female will lay hundreds of eggs over the course of several days or months. Some species lay their eggs inside plant material, either on the surface of the water or submerged. Others encase their eggs in a jelly-like substance and deposit them directly into the water. Eggs usually hatch within a few weeks, although some remain in the water throughout the colder months and hatch the following spring.

The first larva that hatches from the egg is known as a prolarva, and this very quickly moults into the first proper larval stage. The larvae, or nymphs, then proceed to moult a further 514 times – typically taking place over 12 years, although it can be as long as five years in species such as the Golden-Ringed Dragonfly. Nymphs continue to live in the water and are voracious eaters, feeding on insect larvae, crustaceans, worms, snails, tadpoles and even small fish.

Unlike many other flying insects, such as butterflies and moths, the final moult of the dragonfly does not feature a pupal stage – known as incomplete metamorphosis. This moult takes place out of the water where the winged adult emerges from the nymph skin, leaving behind an exuvia, or skin cast. A period of time is then spent feeding away from the water before the adult dragonfly returns to breed and begin the cycle again. Life expectancy of the adult dragonfly is short – typically only 12 weeks, although some will live for up to 56 weeks.

Conservation and climate change

An IUCN update in December 2021 stated that the destruction of wetlands is driving a worldwide decline in dragonflies. Despite their high ecological value, marshes, swamps and boggy areas continue to be degraded by intensified agriculture and urbanisation and, along with longer periods of drought, this is vastly reducing the amount of habitat in which dragonflies and damselflies can survive.

Clean water is also paramount for dragonfly nymphs – so much so that their presence is regarded as an useful indicator of wetland health. Pollution of waterways and water bodies by pesticides and effluent are problematic and are compounding the issue of habitat loss.

In their favour is the fact that dragonflies are highly mobile and appear to colonise new habitats relatively rapidly. With global temperatures on the rise, we are already seeing species shift to higher latitudes and altitudes. Even in the UK, Mediterranean migrants are being recorded with increasing frequency.

There are just under 30 species of dragonfly living in the UK. Identification of these is primarily achieved using the patterns and colouration of the thorax and abdomen, although a few similar species require the finer details, such as leg colour, to be examined.

Take a look at our article The NHBS Guide to UK Dragonfly Identification for ten of the most common and widespread species you are likely to spot in the UK.

Or why not check out this interactive map from the British Dragonfly Society where you can search for good places to look for dragonflies near you. You can also filter the results by species if you’re looking for something specific.

How to attract dragonflies to your garden

Water is an integral part of the dragonfly life cycle, so having a pond in your garden is by far the best way to attract them. If you only have a small outdoor space then sinking a bucket or trough into the ground is a low-cost and space-efficient solution. A larger pond with both floating and emergent vegetation, however, will provide dragonflies with somewhere to lay their eggs and for the nymphs to live once they have hatched. It is important to have some vegetation which extends out of the pond as this will allow nymphs to leave the water when they are ready to undergo the final moult into their adult, winged form. Ponds with carnivorous fish or those used by waterfowl will be less useful as these will both prey on the dragonfly larvae.

Having a variety of flowers and herbs growing nearby will help to attract other insects which the dragonflies will feed on. Providing some canes or small stakes will also give them a place to perch – this is particularly important in the morning when dragonflies need to spend time basking in the sun before their wing muscles are warm enough for flight.

Fun facts

• Dragonflies see the world in colour and can detect ultraviolet as well as blue, green and red.
• Dragonflies have been around for 300 million years. Their ancestors were some of the largest insects ever to have existed – some had wingspans of up to 80cm!
• Dragonflies are true acrobats and can fly both upside down and backwards.
• Although they can live for up to five or six years, dragonflies only spend a tiny portion of this time – between a week and two months – as the colourful flying adults that we recognise. The majority of their lives are spent in the water as nymphs (larvae).
