Rare Natterer’s bat in the Netherlands

This is a video of Natterer’s bats leaving the tree where they had been sleeping.

Recently, in the Rapenhaupt area of the Dutch city of Groningen, two wintering specimens of the rare Natterer’s bat were discovered. This is only the second time that this species has been observed in Groningen province, the Dutch Mammal Society says.

Other bat species in this area include long-eared bat, common noctule bat, and whiskered bat. Total: nine bat species, which is a lot for a city environment.

A Brown University-led team strapped microphones onto heads of big brown bats and recorded the sounds they emitted and the echoes that returned to learn how bats detect objects in space and successfully maneuver around them: here.
