This video from the USA says about itself:
Translated from Dutch Vroege Vogels radio today:
Of the 17 species of bats in the Netherlands, 7 live at Groeneveld [estate in Utrecht province]. This is a paradise for the flying mammals. In the ice house the Natterer’s bat and the brown long-eared bat overwinter, in the coach house there is a small common pipistrelle colony, and in hollow trees in the park are serotine bats, brown long-eared bats and Daubenton’s bats.
Nathusius’ pipistrelles occur at Groeneveld as well.
