Watching Wildlife – Part 2 – Nest Box Cameras

This is part two of a two-part series that will look into different ways of watching wildlife in your back garden. Part 1 looked at trail cameras. In this second part, Antonia Peacock will take a look at nest box cameras and advise you on what to look out for when buying one.

There is a whole world of wildlife in our back gardens, but often these creatures can be elusive or hidden away.  Our range of wildlife equipment can offer you an amazing insight into their world from the comfort of your house, without the risk of disturbing your wildlife.

Come early spring, our garden birds will begin their breeding season. Placing a nest box in your garden will not only give breeding pairs a helping-hand in finding somewhere safe to have their young. But it also provides an opportunity for you to get up close and personal with the goings-on inside with the use of a nest box camera. There are several options and kits out there and a few things to think about when it comes to picking a nest box camera. Here, I will offer some advice and options to ensure you can find the kit that is right for you.

Wired, Wireless or WiFi?
The difference in nest box cameras come mainly in the way that you receive images from the camera itself. These are either wired, wireless or WiFi. Wired kits can provide better, higher quality, more reliable images, but are sometimes not as convenient as Wireless or WiFi kits. Note that even in wireless or WiFi kits, the camera itself still requires power from a nearby mains source (extension leads are available to buy separately.  Alternatively, wireless or WiFi cameras can be powered by an external rechargeable battery that can last up to 36 hours on one charge.

Kit Contents
If you are completely new to nest boxes and nest box cameras, complete kits are available with a nest camera already mounted inside a nest box. Alternatively, if you are looking to purchase a nest box camera, but you already have a nest box, then you can buy nest box cameras separately

Viewing your footage
You can view your footage in a variety of ways depending on what camera or extra equipment you have. Wired cameras plug straight into your TV with an AV cable (included in wired camera kits). If you would like to view and record footage on your laptop or computer instead, you can buy a USB video capture device for both Windows and MacOS. These devices come with software that enable you to set up motion detection or schedule recording, ensuring you don’t miss any exciting moments.

With wireless kits, the footage is transmitted to a receiver which can then plug directly into your TV or PC using the provided AV connectors. Alternatively like the wired cameras, you can use a USB capture device to enable PC or laptop recording.

WiFi cameras transmit their footage over their own WiFi connection. This means you can connect your smartphone, tablet or PC to the camera’s WiFi to view or record footage.

Watch live footage from anywhere in the world straight from your nest box with the live-streaming capabilities of the IP nest box camera, great to share with your friends and family. The camera plugs directly into your internet router or network switch via an included ethernet cable and once set up on a PC or smartphone app, you can share or watch your footage wherever you are in real-time.

If you need to use a wireless camera, a Digital Video Recorder kit is also capable of live-streaming. The wireless receiver can be plugged into the DVR which can be connected to your internet router to enable live-streaming. The DVR itself allows you to set up motion-detection or scheduled recording. You can also add up to four cameras to the DVR which may be useful if you want to watch from multiple angles or from multiple nest boxes.

Species
You may have a particular species of bird in mind that you are hoping to capture on your nest box camera. Our nest box camera kits with boxes are aimed towards common garden birds. The species of birds that you may attract depends on the entrance-hole size.

Nest box
Nest Box Camera Starter Kit

A 29mm hole, such as that of the Nest Box Camera Starter Kit, is suitable for Blue Tits, Coal Tits, Marsh Tits, Great Tits, Tree Sparrows and flycatchers. A larger 32mm hole, such as that of the Gardenature Nest Box Camera System, is suitable for House Sparrows, Nuthatches, Blue Tits, Coal Tits, Marsh Tits and Great Tits. It also has a removable front panel that is ideal if you are looking to attract robins or wrens.

Nest Box Camera Kit
Nest Box Camera Kit

The Nest Box Camera Kit has a removable 29mm plate that can attach over its 32mm hole meaning it is capable of attracting a range of species. If you are looking to attract anything larger or a more ‘picky’ species, then you may want to buy a species-specific nest box and fit one of our separate nest box cameras to this.

Staff Picks 2018

Welcome to our annual round-up of the books and equipment we have most enjoyed reading and using this year, all chosen by members of the NHBS team. Here are our choices for 2018!

 

A Pocket Guide to Wildflower Families 

I am a complete amateur when it comes to botanising. I have struggled in the past to make sense of botanical field guides, and they always left me feeling rather stupid and frustrated. This booklet came to my rescue on my walks this year, and helped me make sense of both the plants, and the features to recognise them by, and the field guides! The author, Faith Anstey wrote a great article for the NHBS blog, and with this blog and her Pocket Guide (and her other books), she has done an enormous service for those who need a friendly guiding hand.
Anneli – Senior Manager

 

Wilding

The process of returning the land to nature has a name that is rapidly entering the mainstream; ‘Rewilding’ or as Iasbella Tree’s book refers to ‘Wilding‘. The subject provokes great debate among conservationist and Isabella’s book certainly doesn’t sit on the fence when it comes to Knepp’s experiment. But her book is written with passion and knowledge and whatever your viewpoint, there is no doubt this book has put Rewilding onto the agenda and could be a game-changer when it comes the stewardship of our countryside in a post-Brexit Britain. Everyone who cares about wildlife and nature should read this book.
Nigel – Books and Publications

 

Seasearch Guide to Seaweeds of Britain and Ireland

As a Marine Biology Graduate I automatically drift to marine-based books, and the Seasearch Guide to Seaweeds of Britain and Ireland is no exception, climbing straight to the top of my field guide list. Finding an available, accessible, up-to-date guide to Britain and Ireland’s seaweeds is incredibly hard, especially one that covers all the Brown, Red and Green seaweeds! As an avid seaweed-presser I’m fascinated by seaweed diversity and this guide helps me find and identify the common, rare and invasive species that line our coasts, thanks to its detailed descriptions and distribution maps. I recommend all naturalists who have not yet attempted seaweed identification to seize this opportunity to branch out.
Kat- Editorial Assistant

 

Landfill

I have long considered gulls a paragon of the bird world, here’s a family whose numerous members excel in flight, at sea, and on land, even navigating the fast-changing urban landscape we have created, and not one of these facets kowtows to lessen another. In the wake of some popular gull identification guides in 2018, Tim Dee and the good folks at Little Toller bring us Landfill – a compact, thoughtful and beautifully crafted gem of a cultural companion to these adaptable birds. Landfill also highlights how our wasteful, short-sighted march has shaped their fortunes and our relationship with them.                                         Oli – Graphic Designer

 

BeePot Bee Hotel

The BeePot Bee Hotel is my favourite piece of equipment this year. It is stylish, sleek and is of course fantastic for bees! Solitary bees use this as a safe nesting space where they lay their eggs and where they can find refreshment from pollinator-friendly plants planted in the top. Ideal for gardeners or nature lovers! Check out the wider range of products which can be integrated into buildings here.             Bryony – Wildlife Equipment Specialist

 

The World in a Grain

The staff picks are becoming increasingly hard, as I have read even more books than last year. The World in a Grain is one of several books this year that made a large impression on me. Most people can name at least a few current or upcoming resource crises, but I doubt many people would rank sand amongst a natural resource that we could run out of any time soon. But, as Vince Beiser shows in this hard-hitting piece of investigative journalism, we are and the prospects are unsettling, to say the least. An excellent read that does not shy away from difficult questions and uncomfortable truths.

The Orchid

I’ve always loved orchids, despite my inability to grow them. The Orchid is an unusual and delightful book containing  many fascinating stories about this beautiful and ubiquitous plant. Supplemented with notes and letters from the Kew archives and 40 botanical prints featuring illustrations by great orchid artists such as John Day and Sarah Drake, it will make a great present for any orchid-devotee.
Soma – Marketing Coordinator

 

Droll Yankees Lifetime Seed Feeder

After starting to feed the birds in our outside space at NHBS, I quickly realised that the Droll Yankees Lifetime Seed Feeder was needed to provide our local birds with food  over the winter months! The prominent perch extensions and robust design makes this bird feeder my staff pick of 2018.                                                                 Marie – Warehouse Coordinator

 

Reindeer: An Arctic Life

I always get excited about a new Reindeer book, especially if it’s about the Cairngorm Reindeer Centre (my favourite place to be in the UK!). Reindeer: An Arctic Life is a wonderful introduction to a fascinating species with great facts and anecdotes throughout. You’ll learn so much about Reindeer evolution and behaviour and learn more about how the Cairngorm herd came to be.

Eco Hedgehog Hole Fence Plate 

I once read somewhere that a hedgehog requires something like 20 average-sized gardens to forage in every night! The trouble is that with our tendency to surround our gardens with fortress-like wooden fences, we do not always make access easy for them. The Eco Hedgehog Hole Fence Plate is a nice way to neaten off and protect an access point for your garden visitors and, at the same time, helping to conserve our hedgehogs. You can even buy a pack of two and give one to your neighbour so that they can make their side of the fence look good too! Or go halves! There you go – neighbourly love and hedgehog conservation for very few pennies!                                                                              Jon- Wildlife Equipment Specialist 

 

NHBS Staff Picks 2017

Welcome to our annual round-up of the books and equipment we have most enjoyed reading and using this year, all chosen by members of the NHBS team. Here are our choices for 2017!

Winter Birds

Winter Birds

In Winter Birds, we find Lars Jonsson’s loving portraits of some of the birds that he observed in southern Gotland in the winter months; both the watercolours and the accompanying essays are wonderfully intimate and personal. A fascinating book to dip into on cold and windy evenings, even if (like me) you don’t know your finches from your jays. First published in Swedish two years ago, this is now available in a UK edition, with range maps for both Sweden and the British Isles alongside each species. Expertly translated by David Christie, this is one of my favourite books this year.
Anneli – Senior Manager

Orison for a Curlew: In Search of a Bird on the Brink of Extinction

The Slender Billed Curlew, Numenius tenuirostris, is emblematic of species decline and ultimately extinction. With the last fully-fledged sighting in Morocco in 1995, naturalist and traveller Horatio Clare took up the challenge of sighting this ethereal creature. With precision and clarity and in only 115 beautifully written pages, this book takes the reader on an immersing journey into history, politics, hunting and conservation.
Nigel – Books and Publications

Field Guide to Moths

Field Guide to the Moths of Great Britain and Ireland

As a newbie to the world of moths, this book is a definitive and indispensable guide to UK species (excluding micro-moths). With in-depth descriptions and distribution maps for each species and beautifully clear and concise illustrations, this newly updated guide is a valuable resource and must-have mothing companion, perfect for beginners and pros alike.
Oli – Graphic Designer

Why We Sleep

Why We Sleep: The New Science of Sleep and Dreams

Picking my favourite book of the year wasn’t easy this time, having stepped up my reading efforts this year. But since there has to be one: Why We Sleep is an exceedingly well-written book about the biology of human sleep, and especially the deleterious effects of chronic sleep deprivation that most of us subject ourselves to. Matthew Walker is a gifted writer with a knack for explaining neurobiological principles in clear language and using imaginative metaphors. It actually made me undertake some very serious attempts to change my sleeping habits.
Leon – Catalogue Editor

The Lost Words

For anyone even vaguely interested in nature writing Macfarlane needs no introduction.
His series on landscape, place and imagination has enthralled me since I first picked up The Old Ways several years ago.
Created in response to the nature-related words culled from the Oxford Junior Dictionary, words which are considered no longer relevant to a modern childhood, Macfarlane along with artist and author Jackie Morris have created a beautiful ‘spell book‘ for younger readers. A joyful celebration of both nature and language.
Johnny – Customer Services

Dinosaur MonopolyDinosaur Monopoly

Everyone at the NHBS board game club loved Dinosaur Monopoly. A new take on an old favourite, though we all agreed the T-Rex should not be the Mayfair of this board! Have fun excavating sites, bartering for ownership and making (or losing!) the big bucks!
Natt – Customer Service & Dispatch Manager

 

Petzl Tikka Headtorch

The Petzl Tikka is a brilliant head torch – with a light output of 200 lumens, you really get a lot of light for your money! Having five different light settings, it’s great for close up work, and with a range of 60m is ideal for night running/orienteering (with the added bonus of being weather resistant). From personal use, I would highly recommend this to anyone who is after a high quality head torch for a very reasonable price.
Sam – Customer Services

Mushrooms and Toadstools

Mushrooms and Toadstools of Britain & Europe: Volume 1

Mushrooms and Toadstools of Britain & Europe is the long-awaited field guide by Geoffrey Kibby, the highly respected field mycologist. This title stands out from other fungi guides with its detailed and comprehensive identification and field notes, but for me the real highlights are the gorgeous illustrations and diagrams running through the whole text. One doesn’t have to be a serious mycologist to appreciate the beauty of fungi as presented in this book!
Rachel – Customer Services

Kite Caiman Binoculars

Kite Caiman Binoculars

My pick is the 8 x 42 Kite Caiman Binoculars, which are our newest edition to the Kite binocular range. They have an amazing close focus and far reaching power, they’re affordable, bright, and are great quality. The Caimans make the ultimate pair of binoculars in the field for anyone on a budget.
Bryony – Wildlife Equipment Specialist

Squid Empire

Squid Empire: The Rise and Fall of the Cephalopods

Covering hundreds of millions of years, Squid Empire tells the fascinating story of how the squishy squids we have in our ocean today became what they are. Written with humanity and wit this book is extremely approachable, even by a layperson such as myself.
Luke – Web Developer

The Plant Messiah

In his time working at Kew Gardens, Carlos Magdalena has managed to track down and propogate some of the world’s most threatened plant species. Many of these success stories are shared in The Plant Messiah and all are recounted in Carlos’s enthusiastic and charismatic style. Part memoir, part “botany-101” and part plant elegy, I found this book difficult to put down, and whizzed through it in just a day or two. It is inspiring, thrilling and educational – what more could you ask for?
Luanne – Senior Editor

pH Meter Calibration and Maintenance

pH Meters
A pH meter is a key part of the field and lab worker’s tool kit.

Modern pH meters are extremely efficient and provide highly accurate results if they are well looked after and correctly calibrated. A key part of this is taking care of the pH electrode. In this post we will discuss how you can maintain the accuracy and lifespan of your equipment by following correct pH meter calibration, cleaning and storage guidelines.

The main components of the pH meter are the glass electrode and reference electrode which are housed together inside a thin glass membrane. The pH meter calculates pH by measuring the difference in potential, or voltage, between the two. A well cared for electrode will last for up to two years, although use at very high temperatures or with abrasive chemicals may reduce this. It is also important to make sure that you have the correct meter for your sample type: for example, a pH meter designed for use in soil samples will have a different electrode type to one which is designed for liquids.

To maximise the lifespan of your electrode and ensure that it provides consistently accurate readings, a small amount of care and attention is required. Below we answer the most common questions relating to pH meter calibration and care.

How do I calibrate my pH meter?

193227pH meter calibration requires two or more pH buffers. A buffer is a solution of known pH which is used as a standard to ensure the electrode is producing accurate results. The most commonly used buffers are pH 7.0, 4.0 and 10.0. Some pH meters will require two buffers for calibration whilst others require three or more. If you are using only two buffers then you will begin your calibration with the pH 7.0 solution and then use either pH 4.0 or pH 10.0 as your second buffer, depending on whether your sample is acidic or alkaline respectively.

The instructions provided with your meter will detail the calibration process. In general, this will involve dipping your electrode into a buffer and waiting for the reading to stabilise. You will then adjust the pH meter to read the correct pH on the display or, if your meter features automatic calibration, it will automatically adjust itself. This process is repeated with the following buffer(s) until the process is complete and the meter is ready to use. Always remember to rinse your electrode in distilled water between different buffer types and make sure to read your manual carefully before calibrating the meter for the first time.

Buffer solutions are available to purchase in 500ml bottles or as packs of 20ml sachets. Sachets are ideal for infrequent use or for use in the field.

How do I clean my pH electrode?

227513Cleaning your electrode will ensure that it stays in optimum condition and will help to maintain accuracy and efficiency. To use a cleaning solution simply place your electrode in it for 15 to 20 minutes then rinse with distilled water and store as recommended below. For pH meters which are designed for use in soil, a cleaning solution for soil deposits is available which will help to eliminate all impurities and residues which are left on the electrode after use.

How do I store my pH electrode when not in use?

180243When your pH meter is not in use the electrode should be kept immersed in storage solution. This stops the electrode from drying out and keeps it clean and protected until required again. Most pH meters come with either a specially designed cap, into which a small amount of storage solution can be added, or they come with a storage bottle which can be topped up with solution. Make sure to check the level of the storage solution regularly as it will evaporate over time. If the electrode is allowed to dry out then it will no longer function correctly and will have to be replaced.

Take a look at the NHBS website for our full range of pH meters, buffers, cleaning and storage solutions. For replacement electrodes, please contact us to discuss your requirements by phoning +44 (0)1803 865913 or emailing customer.services@nhbs.com

 

Made by NHBS – The Ichthyoplankton Net

These bespoke nets, made by NHBS, are being used by ZSL in an ongoing project to monitor juvenile and larval fish populations in the Thames.
The Ichthyoplankton Net

Earlier this year we were contacted by the Zoological Society of London (ZSL) who were interested in working with us to make a bespoke aquatic survey net.

Their specifications required the net to have a square frame with a four point bridle and connections for a flow meter. It also needed to have a diving vane which would ensure that it could be towed stably at a set depth, and a screw on cod end with a bag made from 53µm and 250µm mesh. Following these guidelines, our engineer and seamstress got to work and within a couple of weeks a detailed specification was agreed. The nets were then manufactured and two were sent to ZSL in February.

First draft of the net design

Several months later we were delighted to receive some photos from Anna Cucknell, who manages ZSL’s work on fish conservation in the Thames, showing the nets in use.

 

 

“It was great to work with NHBS, who listened to our specific needs to design bespoke sampling nets for juvenile fish, and used their experience to adapt our designs to fit our needs. Our juvenile fish surveys on the Thames are the first of their kind, in scale and resolution and we hope the results from which will be applicable in the Thames and further afield to help drive conservation and better management of our estuaries for all fish species”.
Anna Cucknell, Thames Project Manager, Zoological Society of London

Ichthyoplankton Net in the Thames
Nets are towed both at the surface and at a depth of two metres. Combined with data from seine and intertidal nets, these surveys provide a comprehensive picture of larval and juvenile fish populations.
Fish Conservation in the Thames

The nets we made for ZSL are being used for an ongoing project to monitor the use of the Thames by juvenile fish.

The Tidal Thames is home to more than 100 fish species including many that are commercially important such as Dover sole and European seabass. It also provides critically important habitat for rarer species, including European smelt and European eel.

Like most estuaries, the Thames provides invaluable spawning, migratory and nursery grounds but, despite this, the region is poorly studied. The ZSL project hopes to remedy this by providing essential information about the health of fish populations in the estuary, and to assess how these are affected by water quality and local developments.

Boat-based sampling for juvenile fish

The project, funded by Tideway, involves both boat-based and foreshore sampling and, excitingly, also provides an opportunity for volunteers to get involved via its citizen science scheme. Volunteers can help with a variety of tasks including measuring, identifying and counting the fish.

For more information about the Tidal Thames fish conservation project, head over to the ZSL website

The NHBS Guide to Hand Lenses

The possession of a hand lens is one of the defining characteristics of a naturalist.

We use them for everything from peering at beetle genitalia and examining floral characters, to examining the arrangement of teeth in small mammal jaw bones. There are a wide variety of hand lenses on the market so how do you decide which lens is best for you? This article contains all the information you need to make an informed choice.

Glass versus plastic lens?

The optical lens in a hand lens can be made from glass or plastic. Plastic lenses are generally more affordable and lighter but are of lower optical quality and are more difficult to clean. Plastic hand lenses, however, can be a good choice for schools and young children.

How many optical elements?

Canon 400mm

An element is an individual piece of glass within a lens. When you look through a high quality camera lens you will typically be viewing what’s in front of the lens through four to six lens elements, as well as other elements used for focusing and zooming (see image below right).

Paul Canon EF 400mm f/4 DO IS USM By Paul Chin

Hand lenses are constructed with one (singlet), two (doublet) or three (triplet) lens elements. Each one is specially shaped to correct for a particular type of optical distortion, so the more elements, the higher quality the image.

Magnification

A 10x magnification hand lens will be more than adequate for most purposes. Higher magnification lenses tend to be harder to use but are very useful for viewing extremely small objects. If you are unsure of which magnification you need, or think you may need several different lenses, you might consider the Triple Hand Lens (x3, x4 and x5).

Lens diameter

Large diameter lenses provide a wider field of view which means that they are easier to use but they are slightly more expensive to produce.

How hand leOpticron Hand lens, 23mm, 10x magnificationnses are named

Hand lenses are named in the same way as binoculars, with both the lens diameter and the magnification included in the name. For example, the Opticron Hand lens, 23mm, 10x magnification has a 23mm diameter lens and provides 10x magnification.

Using your hand lens

Finally, a quick note on hand lens technique. To use your hand lens correctly, hold the lens close to your eye and then either a) move the subject closer to your eye until it comes in to focus or b) move your head (and the hand lens) closer to the subject until it comes into focus. It’s easy with a little practice so don’t get put off if you find a new hand lens difficult at first. Expect to get close up to what you’re examining – it’s quite common to see naturalists crawling around on the ground to get close to a plant they’re identifying.

Keeping your hand lens safe

It can be very hard to find a much-loved hand lens dropped in long grass or woodland. To prevent this happening, we recommend a lanyard for your hand lens – this has two functions: a) if you have it round your neck you won’t drop it, and b) if you put it down somewhere the bright blue lanyard is easy to spot.

The table below provides a guide to the hand lenses sold by NHBS. More information and specifications of each can be found by following the links. Our full range of lenses and magnifiers can be found at nhbs.com.
