I only have about 60 Little Browns this year which is less than half of the norm for this time of year. I would like to think it is because I changed their
houses all around, and not anything bad like wns. I have noticed that they are conserving energy by coming back in a couple of hours and spending more time in the bat house. I took a photo of a single big brown that has taken to my new bat house painted blue. There is a tiny bat in that same house with the big brown. My bats usually hang aroung until first frost and freezing weather at night. Then they hibernate until sometime in March depending on the weather. When the weather warms for a few days in winter I will get a vistor or two from a small species that does not go to the cave. I usually have one that stays in my west facing attic louver until it really gets cold around 20 degrees F. I have 6 bat houses up with 4 being used by one or more bats. I took photos tonight and saw a couple of freetails, but that is way down from normal. They roost with the little browns.
