Roosting of Myotis myotis in a tree hollow in the Czech Republic (Chiroptera: Vespertilionidae)

Abstract

Roosting of Myotis myotis in tree hollows is not common in the Czech Republic, and this phenomenon has not been a subject of a specific study. Here I report on a finding of one individual of M. myotis roosting in a natural tree hollow made by the black woodpecker in a beech forest near Voleč in the Pardubice Region. The bat was found during inspection of 35 cavities in a search for nesting birds. Such a survey has been conducted annually since 2009 and continues extensively till now with 1–4 inspections per season from March to June.
