This Saturday, the Jersey Bat Group will celebrate International Bat Night.
The group will lead a walk around Val de la Mare Reservoir where participants can experience the countryside at night.
Bat detector machines will be used to hear the ultrasonic calls being made by bats.
Members will also be talking about bat biology and ecology and will also be on hand to answer any bat questions.
Participants will be able to watch the bats whizzing backwards and forwards across the reservoir hovering up midges.
Their ‘feeding buzzes’ will be heard as they hone in on their prey.
