In previous winters we often had Noctules Nyctalus noctula in this bat house, but only until the first frost. They left the bat house when it got too cold.
This picture was made after a month of cold weather with snow and frost every day. There were at least five Noctules still present in the bat house. I hope they are OK and are not suffering from frostbite. The bat house gives little protection against frost.
Greetings and all the best for 2011!
