Nyclalus leisleri - Leisler's Bat
Leisler's bat is quite common throughout Wales. It is a medium-sized
species with a dark face, short, rounded ears and shaggy brown fur. The
head-and-body length is typically 50 mm to 68mm, and Leisler's bats usually
weigh between 11 and 20 gm.
Habitat and flight
This is a fast-flying bat, often seen feeding on the insects that gather
around street lamps.
Roosts
Leisler's bats often have their summer roosts in hollow trees. They also
roost in buildings, where they sometimes breed, and are known to make use
of bat boxes. In Wales, their maternity colonies are usually relatively
small (20 to 50 bats).
For their winter roosts Leisler's bats may make use of hollow trees,
but little is known for sure about their winter behaviour.
