Habitat preferences of Daubenton’s bats (Myotis daubentoniid Kuhl 1819: Vespertilionidae) and their prey (PDF)
The small, (6-12g) Daubenton’s bat has a wide distribution ranging throughout the Palaearctic over the whole of Europe, Russia, Central Asia and outer India. Individuals feed almost exclusively over water, usually in the 0.3 1.0 m airspace above the water by either aerial hawking insects from the air or gaffing prey from the surface using […]

Sexual segregation and differential habitat use by Daubenton’s bats (Myotis daubentoniid) in Wharfedale (PDF)
Recent work on Daubenton’s bats in Upper Wharfedale funded by The National Trust and The Environment Agency has revealed an unusual population structure. There appears to be a marked sexual segregation, with females occupying the lower reaches of the river, while the upper reaches are populated exclusively by males. Daubenton’s bat is heavily reliant on […]
