After some chilly nights it warmed into the 60s today so I decided to take some bat house photos. As I have posted before, I really believe that some bats can forecast weather. Anyway the photos revealed two bats in one house and my little resident bat in another. On cold nights below 30F, even my resident bat disappears. Tonight Dec 31,2011 I have 3 bats here.
