I checked my unvented bat house tonight with a flashlight and saw movement. This house is in the same location it was last year on a metal pole in the back yard. I got my camera, and while the shot is not great it clearly shows some bats.
From the color, I would say they are the freetails paying me a visit. Tomorrows forecast is for snow/rain with a high of 36
and a low in the 20s. These freetails have a real attachment to my houses and some were born here last summer. I am very pleased as they are not common here in my area. I relocated two houses and hope the little brown nursery colony will use them in the new locations.
