buildings, as well as bat boxes.It emerges 20 - 30 minutes after sunset and has a fast, erratic flight at head height, Heterodyne bat detectors are great way to detect bats in the field and are easy to use. Magenta Electronics have produced two models, Magenta Bat 4 Bat Detector and Magenta Bat 5 Bat Detector that are worthy of consideration if you keen to getting batty this summer. before. It has fast, straight flight above trees in open habitats and dives less steeply than the Noctule bat when hunting.

Some species like pipistrelle make echolocation calls through their mouths, others like Horseshoe Bats make calls through Bat detector call description: continuous loud bubbling warbling. Calls are very directional and difficult to detect. Noctule Bat (Nyctalus noctula) The Elekon Batscanner (frequency range 15 – 120) is an easy-to-use bat detector, which detects the main frequency with the briefest of flybys, giving a good initial estimation of species, without missing a bat. Its features include: The Lela Bat Box and the Gabriella Bat Box are wood concrete bat boxes designed to provide roosting space for a variety of crevice dwelling species. The Lela has two internal crevice chambers and the Gabriella contains one extensive single compartment.The Daubenton's is a widespread and common bat, found throughout Britain. With a wingspan of 230 - 275mm, this medium sized bat unless you possess the appropriate licence. If a building has a bat roost, the building cannot be developed without wingspan and roosts in trees, timber framed barns and stone buildings.It emerges 40 - 60 minutes after sunset and has UK bat populations have declined considerably during the past century. They continue to be threatened by various factors

These are great entry level detectors which are ideal for detecting bats in real time in the field. Heterodyne bat detectors are also the least expensive detectors on the market. However, you are limited in the number of bat species that you can survey at any one time and there is no facility to record or analyse the sounds. We have both the Magneta Bat 4 and Magneta Bat 5 and have had many hours of fun as bat detectives using both of these models. The bat detector transforms the non-audible ultrasonic sounds into sounds that humans can hear. Our Bat Detectors have a wide frequency range, but it is recommended to initially set the detector at 45kHz, as most bats call through this

This practical guide is perfect for learning more about bat species identification, the equipment used and bat call analysis. These headphones are comfortable and good quality, ideal for use with bat detectors as well as MP3 players and other portable units. Has 30mm drivers for excellent sound reproduction Bats use calls for communication, navigation and hunting but these are at frequencies above that of most human hearing. So even if you’re watching dozens of bats above you, you’re unlikely to be able to hear their calls. Bat detectors are devices that convert these ultrasonic calls into audible sounds and because different bat species call at different frequencies, bat detectors can even help you identify which bat is calling. Bat detectors are great fun to use and can help you learn a lot about bats. There are several different types of bat detectors on the market, at varying prices and with varying features. We’ve highlighted some of our favourite, entry-level bat detectors below. Magenta 4& Magenta 5– Heterodyne This widespread but rare bat can be found in England and South Wales. A small species with a wingspan of 245 - 290mm, it The BATSCANNER STEREO is an easy to use bat detector. It converts the ultrasonic bat calls into an audible frequency with the „mixer“ principle (heterodyne). What makes the BATSCANNER STEREO unique is that the mixing frequency is adjusted and displayed automatically for the detected bat species. Thus, the different bat species can be heard without manual tuning and its main frequency can be seen easily.

All the good features of the original are there, including high level audio output, and built-in front-facing weatherproof loudspeaker. Britain's most common bat, the pipistrelle, is only 4cm long and weighs about 5 grams - less than a 2p coin! and usually roosts in trees, rarely in buildings.It emerges 30 minutes after sunset and flies at different heights in The social calls of bats are an area about which relatively little is known, with more research still required to expand our understanding. This book summarises what is understood so far about social calls of the bat species occurring in Britain and Ireland, and north-west Europe. Due to Martin's exceptional service I was good to go with the surveys, and I really would like to thank Martin and Wildlife Countryside Services for making the dusk surveys happen."Heterodyne bat detectors are tuneable, you select the frequency range to listen to, and bat calls near that frequency are converted to sounds which you can hear. slow flight, often above roof height. It flies in loops in open areas and much closer to vegetation than Noctule bats. The Magenta 5 digital bat detector has a large frequency range of 10 kHz to130 kHz. The extended low frequency coverage makes it suitable for some insects and birds, as well as bats. species roosts under bridges and in trees, buildings and tunnels. It emerges 40 - 50 minutes after sunset and has fast, This is a combination of a Ultrasonic microphone that plugs into your phone or tablet, and software that you install. With this you can listen to, record and view ultrasonic echolocation calls on a colorful, interactive spectrogram. The software can even suggest the most likely species detected.

Even for those who have a pretty good grasp of what each bat detector can do, it's still often difficult to decide which is the best one for each person.

Full Spectrum Bat Detectors

Boxes are most likely to be used if they are placed in an area where bats are likely to feed, such as near rivers and ponds, This concise and definitive guide presents all 45 bat species that regularly occur in Europe (of which 17 are known to breed in the British Isles). The extensive introduction details the remarkable biology of bats and explores the latest findings in bat evolution, behaviour and echolocation. FSC’s ‘A Guide to British Bats’ is a fold out, laminated guide to help you identify bats through physical appearance and call frequency.
