Noctule Bat
Nyctalus noctula


The UK's largest bat, the noctule roosts in trees and if often seen flying above the canopy of the trees surrounding the wetlands, hunting for insects to feed on.

As with all bats, they come out at dusk and you can recognise them from their strong, fast flight. You might even hear this bat, as unlike other species of bat in the UK, some adults and children can hear the frequency of the noctule’s calls.

Unlike other bats, the noctule does not roost in buildings, preferring bat boxes and holes in trees.
