New Firmware update for the Anabat Scout Bat Detector

Titley Scientific have released a new update for the Anabat Scout Bat Detector. The firmware update (Version 1.0), is an important update that should be applied to all detectors as soon as possible.

The Version 1.0 fixes the following bugs and introduces the following changes:

  • Fixed volume adjustment bug fixed, allowing the detector to remember user-set volumes.
  • Added a trigger min event to settings window.
  • The max memo file time is now set to 10 minutes (was 10 seconds).
  • Added a warning message when clock battery gets low.
  • Disable the audio output when recording a memo; reducing and preventing interference.
  • Fixed a bug that sometimes causes log files to be created in the root directory of the SD card.

Titley Scientific are continually improving the software to add features, remove bugs and address performance issues. It is vital that you install new updates as soon as they become available to ensure your detector runs smoothly.

 

How to perform the update:

Step One – The Anabat Scout is updated by downloading the new software onto an SD card. Simply download the update file using this link (.adx file) and copy this file, in its original format, in the root directory of the SD card. Make sure the file is named scout.adx. You can use the same SD card to update multiple Scouts.

Step Two – Insert the SD card and fresh batteries into your Scout then power it on. After a short period the message: “Firmware update 1.0 available. Would you like to update now?” will appear. Press the “Yes” key (top right hand soft key) to start the update. Do not remove the batteries or power off the detector while the update is being installed. Two squares will scroll across the display while the update is being installed and then the detector will restart. The update is now complete.

Note: To check that the update was successful or that the latest firmware is already installed on the Scout go to: Menu, Other, Update and check the version is 1.0

Solitary Bee Week

Although we are all familiar with the important role that bumblebees and honeybees play in pollination, over 90% of the UK’s 267 bee species are in fact solitary bees. Pollinating animals are responsible for one third of the food we consume and solitary bees are particularly efficient pollinators. Unlike other bees solitary bees do not have pollen baskets and so transfer much more pollen between flowers, meaning a single red mason bee provides a pollination service equivalent to 120 worker honey bees. This makes them a critical resource in our gardens and wider countryside and one that we should all be keen to protect. We have collated some information below on how to help encourage and preserve these fascinating creatures.

Solitary Bee Ecology

Solitary bees use a wide range of nest sites including tunnels in wood or mortar, plant stems and even snail shells. They lay eggs in a series of cells and then block the entrance with materials such as mud, leaves or fine hair. The female lays an egg with a food source, made from pollen and nectar, before building a partition wall and moving on to the next cell. The bee larvae hatch, eat the food source then overwinter as a cocoon before emerging the following summer as adults.

Solitary Bee cells in the Solitary Beehive

There have been extremely worrying declines in insect numbers recorded across Europe, and solitary bees are no exception. The increased use of chemicals in farming, loss of flower meadow food sources and loss of nest sites in hedgerows and gardens are all combining to drive down numbers. The good news is that it is easy to provide food sources and nesting habitat in your garden to help solitary bees and increase pollination. 

Providing Resources for Solitary Bees

Provide food sources for solitary bees by planting wild flower seeds, native trees such as hawthorn and willow, bee friendly plants such as ivy, foxgloves and lavender and allowing plants such as borage and thistles to flower in your garden. Nest sites can be provided by leaving dead wood and stems standing, creating a patch of bare earth or mud bank for mining bees and by installing wild bee houses.

With careful design consideration, bee houses can provide shelter and nesting sites for solitary bees. Bee houses can be manufactured from a variety of materials but should have a good overhanging roof to protect the nesting tubes from rain, nesting holes between 2 and 10mm in diameter and a solid back. It is better to have a number of smaller bee houses, rather than one large house to reduce the risk of parasites finding the nest. Alternatively we have a wide range of solitary bee nesting habitats available on our website.

You can tell which species of bee is using your bee house by examining the material used to plug the entrance hole. Different species also emerge at different points in the year. The most common species likely to populate bee houses are red mason bees who use mud and are active March – July, leafcutter bees who use leaves and are active May – September, and wool carder bees who use fine hairs and are active June – August. Please note that there are fewer solitary bee species in the North of England and Scotland.

Solitary Bee House Siting and Maintenance

Insect houses should be sited at least 1m off the ground, facing south or south-east, with no vegetation covering the entrance and in full sun as insects need warmth to keep moving. They should be firmly fixed so that they don’t move in the wind. If your box is likely to be occupied by red mason bees then it is helpful to ensure that there is a patch of damp mud nearby. In order to maximise the chances of adults emerging successfully from the cocoons, it is a good idea to bring bee boxes indoors into an unheated shed or garage during the winter to avoid them getting too damp. The boxes should then be taken back outside in March in time for the new adults to emerge. There is some debate as to whether brick / concrete boxes should be cleaned but they can be cleaned out with a tent peg and pipe cleaner. Boxes with cardboard tubes should have the tubes replaced regularly. Keep an eye out for failed nests and tiny holes in the mud entrance as this can indicate that the nest tube has been taken over by parasites.

The NHBS Harp Trap

The NHBS Harp Trap 

Earlier this year we were delighted to launch another exciting product manufactured here at our base in Devon. After a concerted period of design and manufacturing effort by our expert Workshop Team, followed by testing and review by ecological professionals, our NHBS Harp Trap was ready for production. The launch of our product into the wildlife equipment market signals the arrival of the only commercially produced harp trap in Europe. 

What is a Harp Trap? 

A harp trap provides an alternative bat survey method to mist netting or the use of bat detectors. They are particularly useful in situations where bats in flight can be channeled through a natural funnel such as above a water course, a cave or mine entrance or a clear area within a forest. 

Harp traps consist of a frame which is either freestanding or suspended, and supports two to four rows of nylon strings. The bats will fly into the nylon strands and then fall unharmed down into a collecting bag below. The catch bag is made from green cotton canvas that is water resistant and breathable and includes heavy duty clear plastic baffles to prevent the bats from escaping. Unlike mist nets, harp traps do not entangle the bats an it has been reported that they can be more effective for surveying bats, potentially capturing higher numbers of individuals. 

The NHBS Harp Trap

The new NHBS Harp Trap is a three-bank trap, meaning it has three rows of nylon line. Our trap has a catch area of approximately 4mand catch bag which is around 60cm deep.  It folds down neatly into a bespoke carry bag and weighs approximately 15kg-full specifications and dimensions are below. The trap takes two people around 10 minutes to assemble and stands on four sturdy, extendable legs and which can be arranged at the height that you need the trap to be. There is also the option to anchor the harp trap with guy ropes in windy conditions. The trap can also be adapted to be suspended if this is required. 

Our trap has a few innovative features designed to make assembly and disassembly easier. Firstly the strings are wrapped  around a winding mechanism which greatly reduces the stress and time-consuming act of sorting through tangled lines in the dark.

 

There is also an extension under the catch bag, which prevents the bats from flying underneath the trap and this doubles as protection for the component parts as it wraps around the disassembled trap when it is stored in its bag. 

Dimensions:

Catch area: 4m2 approximately
Catch area L x W: 180 x 225cm
Length: 180cm
Catch bag depth: 60cm

Testing 

As our harp trap evolved, prototypes were trialed and reviewed by ecology professionals; Professor Fiona Mathews of Sussex University and Neil Middleton of Batability. Their expertise and excellent feedback helped us develop our the harp trap to the point that it was now ready to go live. 

The team at NHBS have done an excellent job in coming up with a new and refreshing approach to harp trapping, which shows many innovative and useful design features.  When testing the equipment we were able to demonstrate that it was quicker/easier to assemble than competitor’s products.  We are happy to recommend this harp trap, and will be ordering one ourselves, to be used during our training courses and for bat-related research.

Accessories

A number of accessories can be bought to help mount and secure your trail camera your camera in the perfect position.

Python Mini Cable Lock

Python Mini Cable Lock
Compatible with all of our retailed trail cameras. This versatile lock has been designed to be extremely resilient to damage and picking, protecting your camera from any potential theft.

Security Boxes
Many of our trail cameras can be contained within a matching security box which provides maximum protection when in the field. All of our security boxes can be locked using a standard padlock or python cable. Make sure when purchasing a security box that it will fit the intended trail camera.

See our full range of Security Boxes on our website.

Batteries
The batteries you use in your trail camera can influence its performance in the field. Lithium-ion batteries are one of the most popular choices because they produce a high voltage per cell (1.6v) giving a brighter LED flash and a greater flash range. Rechargeable alkaline batteries offer a more economical and environmentally friendly alternative, however, when in use their voltage decreases over time and they produce proportionately darker LED flashes and consequently, photographs/videos are less illuminated. Standard alkaline batteries are also a suitable economic alternative.

SanDisk Class Cards
Ensuring you use a high read-write speed SanDisk Class card is highly advised for all of our trail cameras. Be sure to check the maximum SD or SDXC card capacity for your intended camera as these can vary between models and brands.

Solar panels
Where sufficient sun is available, the addition of a solar panel to your trail camera can extend its recording life indefinitely. Bushnell, SpyPoint and Ltl Acorn all offer compatible solar panels for their trail cameras.

All of our trail cameras can be purchased as starter bundles which include an SD card and all the batteries you need to power the camera. The complete trail camera range can be found at www.nhbs.com

Can’t decide which camera you need? Why not take a look at our guide on choosing the camera that’s right for you.

Introducing new microplastics nets from NHBS

The destruction of aquatic ecosystems is a major issue facing conservationists globally – causes include microplastic pollution, acidification, global warming and over-fishing. The manufacturing team at NHBS have produced a series of new survey nets designed to help researchers gather data on microplastics and to sample plankton more efficiently. This blog describes the sea trials performed using our prototype nets to establish the optimal towing speeds and sea conditions as well as whether the nets worked effectively and were robust enough to withstand exposure to the marine environment.
Three new nets were tested – the Manta Trawl Net, which is designed to sample microplastics in calmer inshore waters and on rivers and lakes. The Avani Trawl Net, which is designed to sample microplastics in rougher, offshore environments and the Bongo Net (a pair of 300mm plankton nets joined in the middle and weighted with a depressor vane) which is designed to allow researchers to use two different mesh nets during a single trawl. Plymouth Sound was an ideal location, as we had both inshore and offshore designs to test and the breakwater provided us with easy access to both sheltered water and the open ocean.

The first design tested was the Bongo Net. The net performed very well. The sampling depth was easily adjusted by modulating the speed of the boat and the depressor vane kept the net level in the water.  In our tests the Bongo Net performed best at towing speeds of between two and four knots.

Bongo Net

Next, we tested our inshore Manta Trawl Net. The Manta Trawl Net is designed for microplastics sampling in calm inshore waters and on rivers and lakes. The Manta Trawl Net has a post box shaped aperture and twin ‘wings’ (manta wings) mounted onto the frame which serve to lift the net frame so that samples are efficiently collected at the top of the water column. This net was tested at a variety of towing speeds and performed best at speeds of between two and four knots.

Manta Trawl Net

The last net to be tested was The Avani Trawl Net. The Avani Trawl Net is designed for offshore microplastics sampling. The vertical orientation of the aperture of the net ensures that samples are collected from the top few centimetres of the water’s surface in slight to moderate swell conditions. To test this net, we ventured out beyond the breakwater where the swell was approximately 1-2m. The net stood upright and performed as expected at speeds of between four and eight knots when exposed to smaller waves of approximately one metre in height. When approaching larger waves, we found that the net had a slight tendency to cut into the side of the wave at speeds of between six and eight knots and that the net performed best at slightly lower speeds.

Avani Trawl Net
All of the nets functioned properly, and our haul included both microplastics and icthyoplankton (fish eggs and larvae). Both the frames and the nets also withstood the sea conditions well and we could find no faults with their design or build – all told a successful trial.
If you are interested in these nets look out for them in our 2019 catalogue, find them on nhbs.com, or contact us on customer.services@nhbs.com and we will send you more information as soon as it becomes available.
