Bat walk in Sandridge Parish at Jersey Farm Woodland Park
June 16 @ 9:00 pm - 10:30 pm
Come along and join our evening walk at dusk and see what bats are in our skies! There are eighteen species of bat in Britain and all are protected under the Wildlife and Countryside Act. Although bats have reasonable eyesight they catch their food (flying insects) by using a remarkable form of ‘radar’! As the bat flies through the air it emits a series of ultrasonic squeaks (about 12 – 15 per second). These high-pitched sounds are usually out of range of human hearing, although some lower frequency calls are certainly audible. The sound waves from each squeaking call are projected out in front of the flying bat. As these sound waves come into contact with objects along the flight line they bounce echoes back to the bat’s receiving gear – so allowing the bat to avoid obstacles or to home in on insect prey. We have two bat detectors that can identify the sounds of individual bats and allow us to work out what species they are.
