Light Levels and Emergence
Birds of prey are bats main predators (apart from cats). These bat species have more chance of out-flying a bird of prey and so they can emerge a little earlier to take advantage of the blooms of insect prey present at dusk.
This video clip shows pipistrelle bats emerging from a roost. When bats emerge from the day roost they often follow certain linear features like hedges or tree lines, keeping close to cover to fly to their feeding sites.
It is often the case that more bats are encountered at certain sections of the route but please do not reverse the route or alter it because of this – it must be done in the same way every time.
