Although there are more than a thousand species worldwide, Britain is home to 16 species. All of the British species eat insects, including beetles, moths, flies and midges. They navigate and locate insects by echolocation, making high-frequency ultrasonic calls and listening for the pattern of returning echoes.\u003c\/p\u003e\n\u003cp\u003eIt is an offence to disturb a wild bat unless you have a licence. So beginners should start by trying to identify bats in flight. Fortunately, you can gather initial clues without using any special equipment, and this guide will show you what to look for. Useful information includes size, flight pattern, habitat and emergence time after dusk.\u003c\/p\u003e\n\u003cp\u003eA bat detector will help you proceed with correct identification to species. This guide covers bat identification using both heterodyne and time expansion detectors. Heterodyne detectors, which are generally cheaper, transform the ultrasonic calls into sounds that humans can hear. The guide describes each species’ call. By contrast, time expansion detectors record the ultrasonic calls. The guide gives the frequency range, duration range and sonogram of each species.\u003c\/p\u003e\n\u003cp\u003eField Studies Council worked with the \u003ca href=\"https:\/\/www.mammal.org.uk\/\"\u003eMammal Society\u003c\/a\u003e to produce the Bats guide.\u003c\/p\u003e","brand":"Wilderness Books","offers":[{"title":"Default Title","offer_id":58062203453822,"sku":"9781851538751","price":4.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0996\/4096\/7550\/files\/BatsWildIDguide.jpg?v=1789840737","url":"https:\/\/wildernessbooks.co.uk\/products\/british-bats-wildid-guide","provider":"Wilderness Books","version":"1.0","type":"link"}
