This is a serotine bat video.
On 9 August 2015, Ecomare museum on Texel in the Netherlands reported on bat research on the island.
Only one species, as far as they know, has colonies on Texel: the serotine bat. Serotine bats have been seen on all Dutch Wadden Sea islands; but only on Texel breeding colonies are known.
107 bats were counted during the 2015 Texel count; less than in other years.
