The white bat that occupied my bat houses in summer 2010, a video of which you can see on YouTube ( http://www.youtube.com/watch?v=wj-1RXxq ... ll&list=WL )
did not return this spring.
However, tonight, July 17, 2011, when I was reminiscing about it, out it came!!
Do males mix with females during the raising of young, before they fledge?
I ask because it appeared about the same time last year, after the young bats begin flying.
