NHBS Field Sessions: Waterway Surveys for Daubenton’s Bats

NHBS’ staff members are wild about wildlife! To showcase this, we are encouraging our team to write blogs about their experiences with nature.

During the Summer months, Jon Flynn, a member of NHBS’ Wildlife Equipment Team attended a number of Waterway Surveys for Daubenton’s bats (Myotis daubentonii). Read more about his survey experiences below:

“On Monday 6th July I took part in a Waterway Survey for Daubenton’s bat along a stretch of the River Teign in Devon. The survey is completed twice per year in conjunction with the Bat Conservation Trust and is part of an ongoing data collection programme for bat species around the UK. The lead for this particular survey was John Mitchell who has been surveying this particular length of the Teign, near Teigngrace, for a good number of years. It was my third survey there.

The survey was due to start 40 minutes after sunset, so we met at 9.00pm and made our way along the edge of a maize field to arrive at our first stopping point. This was to be a transect survey which meant walking a length of the river bank and stopping at ten predetermined points to record bat activity at each one. We stood at the river’s edge and immediately noticed that the river level was a lot lower than it was during our last visit a year or so ago. We recorded air temperature and cloud cover and, as we prepared, various species of bats could already be seen zooming around the trees and openings as they commenced another night of nocturnal foraging. The air was very warm, still and humid, and flying insects were everywhere including a host of moths and some less welcome biting species.

As the light faded it was time to start. With bat detectors switched on and earphones in place, we directed a torch beam on the river’s surface and awaited the arrival of the first Daubenton’s.

The Daubenton’s bat is a species which typically occupies riparian woodland.  They often roost in trees along the river bank and hunt by skimming low over the surface of the water for insects. They can take prey from the water’s surface using their feet or tail membrane.

As bats skimmed through the torch beam we were able to count them. We counted the number of passes that we observed and for this a clicker counter is always useful! The bats that we heard but did not see were also recorded as additional information. I set my Magenta 5 at 50hz and listened whilst John relied on his trusty and more accomplished Bat Box Duet.

After four minutes on the stopwatch we finished counting, compared counts and wrote down results. At stop number 1 there were certainly bats present, but they were swooping around quite high above the water surface and not showing the typical behaviour of Daubenton’s – John was dubious that they were our target species so we recorded them only as potential sightings.

Using GPS devices and torches we left for Survey Point 2 further down the river bank and repeated the same process as before. At this location there was no denying that these WERE Daubenton’s bats, as the torch beam caught their pale almost white ventral fur, confirming their identity. Our detectors were full of noise too, including the typical intense zap as a bat homed in on prey.

On we progressed with eight more stopping points to go. Occasionally our river bank scrambles took us through thickets of invasive Himalayan balsam (Impatiens glanduliferaand Japanese knotweed (Fallopia japonica) a sobering reminder of how our countryside is changing. The night remained still and warm and it almost felt like we were in a different country.

After eight more stops my watch said 11:20pm. It was good to see that bats were in profusion that night, as John stated ‘It was one of the best ever totals, with one stopping point recording over 50 passes!‘.

Two weeks later and we repeated the process. But this second night felt noticeably cooler and there were fewer insects on the wing. Nevertheless bats were still out and about in reasonable numbers and an average score was calculated between the two Waterway surveys.  Overall there were encouraging signs that the Daubenton’s bat continues to do well along this particular stretch of the Teign.”

If you like the idea of taking part in Waterway Surveys (or other kinds of bat surveys) then contact the Bat Conservation Trust or have a look at their website here. It’s great fun and you can put your bat detector to important use!

An NHBS field trip – searching for Nightjars

This week a small group of us took a trip to Dartmoor to try and catch a glimpse of Nightjars. As well as getting a chance to see one of the UK’s most elusive birds this was also a great opportunity to field test some of the equipment we sell.

Nightjars are cryptic, nocturnal birds that arrive in the UK in May to breed before migrating south in September. For the best chance to see these amazing creatures you need to head to heathland, moorland or open woodland on a warm, still evening. If you are early enough in the season you may also get a chance to see the males displaying, showcasing a repertoire of wing claps and churring.

This great selection of equipment meant that we could look out for bats and moths as well as Nightjars. Image by Oliver Haines.

So what did we pack for an evening of Nightjar watching? Our kit bag is below:

At the site we visited we were lucky enough to see 2-3 males displaying and, despite the low light conditions, the binoculars were extremely useful for picking out individuals on branches. We were also able to capture some great audio recordings with the SM4 Acoustic recorder which we deployed for a few hours. A sample audio clip from the SM4 can be found below. The Tascam allowed us to record as we watched the nightjars displaying, giving us the chance to record all parts of the display. During the walk back we started up a couple of the bat detectors and were greeted by a few different species including noctules and pipistrelles.

What would we take next time?

A parabolic microphone (Telinga PRO-X or Hi-Sound Mono Parabolic Microphone) would have been extremely useful for getting some high-quality recordings. Although the Tascam worked well by itself, a highly directional parabolic microphone would have allowed us to get higher quality recordings and reduce background noise.

The binoculars performed fairly well given the low light conditions but on the next trip I would be really interested in testing a night vision scope such as the Pulsar Digiforce 860RT as a way to try and spot perched nightjars later into the evening.

We had a great evening observing these fascinating birds and I highly recommend it. Nightjar populations have been recovering recently but they are still an amber listed species. They are highly sensitive to habitat change and, since they nest on the ground, are particularly vulnerable to disturbance from people and dogs. So if you decide to go and observe the Nightjars displaying this summer please be mindful, stick to paths and keep dogs on leads. More information on Nightjar conservation and identification can be found on the RSPB website.

National Insect Week 2018

National Insect Week is organised by the Royal Entomological Society and occurs every two years. In 2018 it takes place from 18th to 24th June.

National Insect Week 2018

Following the shocking news in 2017 which revealed recent drastic declines in insect numbers, insect and invertebrate biodiversity has never been more critical. National Insect Week aims to inspire people of all ages and backgrounds to learn more about insects and the vital roles they play in almost every ecosystem on earth.

To celebrate National Insect Week hundreds of events will be occurring throughout the UK, ranging from Bioblitz days, insects walks, workshops and even the chance to dine out on edible insects. Take a look at the interactive map on the official National Insect Week website to see what’s happening where you live. Or why not organise your own event? Don’t forget to submit the details on the website though so that it can be added to the map!

New to the world of insects?

Why not get started by watching the following videos from the Royal Entomological Society. They provide a brief introduction to the various groups of insects and explain why they are so vitally important to life on earth. If you’re eager to learn more then you can read about all of the main orders of insects here.

Ready to start finding and observing insects outside?

At NHBS we sell a huge range of insect identification guides as well as butterfly and sweep nets, moth traps, handheld magnifiers, bug pots and all the other accessories you need to start identifying insects in the field. Follow the links below to visit the shopping pages on our website.

Hedgehog Awareness Week 2018

The hedgehog is one of the nation’s favourite garden visitors. However, due to severe declines in their numbers, they are now a priority species in the UK’s Biodiversity Action Plan. Image by Peter O’Connor via Flickr (CC BY 2.0).

Hedgehog Awareness Week runs from 6th – 12th May and is organised by the British Hedgehog Preservation Society.

Here are seven ways that you can get involved this year:

1. Donate to the BHPS by texting HHOG18 £5 to 70070, or donate via their Just Giving page. The BHPS is a charity that relies solely on membership and donations. They provide advice to the public on how to care for and encourage local hedgehogs and they maintain a national list of hedgehog rehabilitators. They also raise awareness and support for hedgehogs and fund research into the behaviour and conservation of hedgehogs in the UK.

2. Hold a coffee morning or other fundraising event to raise funds for hedgehogs. Make sure you tag any posts about your event on social media with #hedgehogweek and don’t forget to let BHPS know what you’re doing, so they can keep up-to-date with everything that’s going on around the country.

3. Post some leaflets in your local area letting people know how to care for hedgehogs in their garden and what to do if they find an injured hog. Lots of leaflets can be downloaded from the information section on the BHPS website.

4. Contact your local council or tool hire centre and ask them to put free warning stickers on all of their strimmers.

5. Educate yourself about hedgehogs and their needs. Take a look at our Hedgehog Facts & FAQs blogpost for lots of information or treat yourself to one of the great books about hedgehogs available from NHBS:

6. Make your garden hedgehog-friendly: Attempt to keep some areas wild and overgrown and, if you have a garden fence, cut a hole at the bottom measuring 13 x 13cm as this will allow hedgehogs to pass through on their nightly wanderings. Provide a shallow dish of fresh water along with some dog or cat food, some chopped unsalted peanuts or some sunflower hearts. Finally, make or buy a hedgehog home. This will provide a safe and warm space for hedgehogs to hibernate throughout the winter, and also for a female to raise her young in the spring and summer.

The NHBS Guide to UK Amphibian Identification

 

The UK is home to seven native species of amphibian. Over the winter, these frogs, toads and newts have all been hibernating, but it will soon be time for them to venture out to their breeding ponds and pools. If you’re lucky, you will be able to spot them when you’re out and about.

In this blogpost we will provide you with some of the key characteristics of each species which will help you to identify exactly what you’re looking at. For those of you who are keen to find out more, we have also provided a list of field and identification guides at the bottom of the page.


Newts

Newts are members of the salamander family and have a lizard-like body shape. They are semi-aquatic, spending part of the year on land, returning to the water in spring to breed. Eggs are laid in the water where they hatch into tadpoles and then proceed to develop front and back legs, along with gills for breathing. They leave the water in late summer once their gills have been lost.

The three species of newt which are native to the UK are the Smooth Newt (Lissotriton vulgaris), the Palmate Newt (Lissotriton helveticus) and the Great Crested Newt (Triturus cristatus).

Smooth Newt:

Look for the pale spotted throat. Image by gailhampshire.

• Size: Grows to around 10-11cm in length.
• Colour: Males brown/olive; females light brown. Belly is usually yellowy orange with black spots. The throat is pale with darker spots.
• Skin Texture: Smooth
• Habitat: Spring to early summer in ponds and pools (frequently found in garden ponds). Late summer under logs and stones near to water.
• Other notes: The male has a wavy back crest during the breeding season.

Palmate Newt:

Look for the pale throat without spots and a dark stripe through the eye – this can help you to distinguish it from the smooth newt. Image by Laurent Lebois.

• Size: Grows to around 7-11cm; slightly smaller than the smooth newt.
• Colour: Males olive brown; females yellowish brown. The throat is white/pale pink and does not have spots or speckling. The eye has a dark stripe running horizontally through it.
• Skin Texture: Smooth
• Habitat: During the breeding season (early March to late May) in shallow ponds, often in heathland bogs. During summer in woodland, ditches and gardens near to water.
• Other notes: During the breeding season, the male palmate newt has a ridge running along its back and a tail which ends in a filament. Its back feet are also webbed.

Great Crested Newt

Much larger than the smooth or palmate newt, the male has a large crest which is broken where the tail meets the body. Image by Chris H.

• Size: Up to 15cm in length. Females may be even larger than this.
• Colour: Dark brown or black with white/silver dots on sides. Underside is orange with black spots. Pale throat.
• Skin Texture: Warty
• Habitat: March to May in deep ponds with vegetation. Great crested newts often range further than smooth or palmate newts during the summer and can be found in gardens, ditches and woodland.
• Other notes: The male has a very distinctive crest during the breeding season which is broken at the point where the tail meets the body. The crest also has a silver stripe.


Frogs

Frogs are short-bodied, tailless amphibians that largely lay their eggs in water. These eggs hatch into aquatic larvae, known as tadpoles, before metamorphosing into froglets and then adults.

There are two native species of frog in the UK: the Common Frog (Rana temporaria) and the Pool Frog (Pelophylax lessonae).

Common Frog

Keep an eye out for dark patches behind the eyes and dark barring on the back legs. Image by Erik Paterson.

• Size: Adults grow to 6-9cm in length.
• Colour: Olive green to yellow-brown. Usually spotty or stripy with dark patches behind the eyes and darker barring on hind legs.
• Skin Texture: Smooth and moist.
• Habitat: From late February to early October in all sorts of ponds and pools. Common in gardens.
• Other notes: Moves by hopping. Common frogspawn is gelatinous with black embryos and tadpoles are initially black but turn speckled brown. (This is a useful way of distinguishing them from toad tadpoles, which remain dark until development).

Pool Frog

• Size: Adults grow to 6-9cm in length.
• Colour: Usually brown with dark spots. Light yellow back stripe.
• Skin Texture: Smooth and moist.
• Habitat: Currently only present in localised spots in East Anglia.
• Other notes: Males have prominent vocal sacks on the side of the mouth.


Toads

Toads are characterised by dry-looking, warty skin and short legs. They usually move via a lumbering walk, as opposed to the hopping motion used by frogs. As with frogs, most toads lay their eggs in water. These hatch into tadpoles before growing legs and metamorphosing into the adult form.

Within the UK there are two native species of toad: the Common Toad (Bufo bufo) and the Natterjack Toad (Epidalea calamita).

Common Toad

The common toad moves with a lumbering walk and has distinctive bulges on the back of its head. Image by stanze.

• Size: Females grow up to 13cm whilst males are smaller and usually reach only 8cm.
• Colour: Brown to grey-green. Paler on the underside.
• Skin Texture: Dry-looking and warty.
• Habitat: From late February in damp, shady spots near to breeding ponds. During the summer in woodlands, gardens and fields.
• Other notes: The common toad has amber eyes with a horizontal pupil. Moves with a lumbering walk or small hop. Eggs are laid in strings in a double row. Upon hatching the tadpoles are dark and, unlike frog tadpoles, remain so until they develop. 

Natterjack Toad

The natterjack toad has a yellow stripe down the spine. Image by Bernard Dupont.

• Size: Females grow up to 8cm whilst males are slightly smaller.
• Colour: Pale brown/green, often with brightly coloured red or yellow warts. Yellow stripe down the spine.
• Skin Texture: Dry-looking and warty.
• Habitat: Coastal dunes and lowland heath, often in open, unshaded habitats. The natterjack toad is very rare in the UK.
• Other notes: The natterjack toad has amber eyes with a horizontal pupil. Moves with a running motion, rather than hopping. Lays strings of eggs in a single row.

Hedgehog natural history and biology

The hedgehog found in Britain has the scientific name Erinaceus europaeus. With the exception of some of the Scottish islands, they are present almost everywhere in Britain. Hedgehogs have adapted well to urban habitats where they feed and nest in our wilder areas, parks and gardens. In more rural areas they utilise woodland edges and hedgerows where food and nesting spaces are plentiful.

A fully grown hedgehog measures approximately 260mm from nose to tail and can weigh in excess of 1.1kg, although they may weigh considerably less than this at certain times of the year. The body of the hedgehog is covered in 25mm long spines which provide protection from predators: when threatened, hedgehogs will roll into a tight ball with their face, belly and limbs tucked carefully inside.

Hedgehogs are omnivorous, feeding preferentially on beetles, caterpillars and earthworms, as well as slugs and snails. For this reason they are often referred to as the ‘gardener’s friend’. During the night they will travel long distances, eating as they go, before finding somewhere safe and sheltered to sleep during the day. A single hedgehog may travel up to 2km in a single night!

Between November and the end of March, hedgehogs hibernate to conserve their energy, as there is very little food available for them during these months.

Current status of hedgehogs in the UK

In the mid-1990s the JNCC produced a review of British mammals, in which the population of hedgehogs in Britain was estimated at 1.55 million. Since then, citizen science schemes such as the BTOs Breeding Birds Survey and Garden Birdwatch, together with PTES’ Mammals on Roads and Living with Mammals have all contributed data to the picture, reporting significant declines in both rural and urban areas.

This picture is a cause for concern, not only for the hedgehog itself but because, as a generalist species, their presence is a good indicator of ecosystem health. Their declines suggest a loss of key soil invertebrates and important landscape features such as hedgerows, as well a reduction in habitat connectivity.

As a result of these declines, the hedgehog was made a priority species in 2007 as part of the UK Biodiversity Action Plan.

Encouraging hedgehogs in your garden

Many modern gardens are designed to be aesthetically pleasing but are not hospitable for local wildlife. Tidy lawns and well-maintained fencing, although neat to human eyes, provide little to attract the humble hedgehog. However, there are a few simple tips you can follow to make your more garden more appealing to them:

• Attempt to keep some areas wild and overgrown, as this will provide secure nesting and feeding spaces.

• If you have a garden fence, cut a hole at the bottom measuring 13 x 13cm as this will 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.

• Try not to use pesticides or slug pellets, as these are poisonous to other animals as well as slugs.

• Provide a shallow dish of fresh water along with some dog or cat food, some chopped unsalted peanuts or some sunflower hearts.

• Make or buy a hedgehog home. This will provide a safe and warm space for hedgehogs to hibernate throughout the winter, and also for a female to raise her young in the spring and summer.

• Take care when mowing or strimming your lawn, particularly if your grass is very long to begin with.

Other ways to help

• Contribute to Hedgehog Street’s Big Hedgehog Map – by pledging to make a hedgehog hole in your garden wall or fence then registering this on the map, you can contribute to the network of hedgehog-friendly gardens that is being created all around the UK. You can also report a hedgehog sighting for addition to the map.

• Join the British Hedgehog Preservation Society – as well as raising awareness of hedgehogs and the challenges they face, the BHPS also helps to fund research into hedgehog behaviour and provides financial support to hedgehog carers.

• Take part in a citizen science project – schemes such as the BTOs Breeding Birds Survey and Garden Birdwatch, together with PTES’ Mammals on Roads and Living with Mammals surveys, provide essential data about our local wildlife, all of which would be impossible to collect on such a large scale without the help of 1000s of volunteers.

• Educate yourself about hedgehogs in the UK. Take a look at one of the excellent books below, or do some research online. This great guide provides lots of information about looking after the hedgehogs in your garden.

Top 10 Bat Boxes for New Builds and Developments

Schwegler 1WI Bat BoxLooking for a bat box but don’t know which one to buy? This article is the third in a three part series designed to help you to make the right choice. Here you will find our top 10 boxes for incorporating into the masonry of a new build or development. The previous two posts feature the best boxes for trees and woodland and for walls and fences respe.

For each box listed you will also find helpful information such as its dimensions and weight and the box type (e.g. whether it is for summer use, for hibernation or for access into an existing roost space).

The Glossary below provides a guide to the key terms used in the descriptions.

• Woodcrete/WoodStone: A blend of wood, concrete and clay which is very durable. Is is also breathable and helps to maintain a stable temperature inside the box.
• Summer: Summer boxes are suitable for the warmer months but are less likely to be used over the winter.
• Hibernation: Designed to be larger and better insulated, hibernation boxes will provide a safe and warm space for bats over the winter.
• Maternity: Suitable for the formation of colonies and raising of young.
• Access: Provides an entrance to an existing roof space such as a wall cavity or loft.
• Crevice: Provides one or more narrow roost space. Species which prefer this type of box include common, soprano and Nathusius pipistrelle, Brandt’s and whiskered bats.
• Cavity: Provides a more spacious roost space. Bats such as brown long-eared, Daubenton’s and Natterer’s bats prefer cavity boxes.
• Large cavity: These boxes allow space for flight within the roost which is preferred by brown long-eared bats in particular.

Top 10 Bat Boxes for Walls and Fences

Improved Cavity Bat BoxLooking for a bat box but don’t know which one to buy? This article is the second in a three part series designed to help you to make the right choice.

Here you will find our top 10 boxes for installing on an external wall or fence. The first and third posts cover the best options for installing on a tree in a garden, park or woodland and for building into a new build or development respectively.

For each box you will also find helpful information such as its dimensions and weight and the box type (e.g. whether it is for summer use, for hibernation or for access into an existing roost space).

The Glossary below provides a guide to the key terms used in the descriptions.

• Woodcrete/WoodStone: A blend of wood, concrete and clay which is very durable. Is is also breathable and helps to maintain a stable temperature inside the box.
• Summer: Summer boxes are suitable for the warmer months but are less likely to be used over the winter.
• Hibernation: Designed to be larger and better insulated, hibernation boxes will provide a safe and warm space for bats over the winter.
• Maternity: Suitable for the formation of colonies and raising of young.
• Access: Provides an entrance to an existing roof space such as a wall cavity or loft.
• Crevice: Provides one or more narrow roost space. Species which prefer this type of box include common, soprano and Nathusius pipistrelle, Brandt’s and whiskered bats.
• Cavity: Provides a more spacious roost space. Bats such as brown long-eared, Daubenton’s and Natterer’s bats prefer cavity boxes.
• Large cavity: These boxes allow space for flight within the roost which is preferred by brown long-eared bats in particular.
