Yesterday, I was out walking around enjoying some of the new fall color and the lovely day. I decided to take another look at the bat house and see if there was any action.  And.....YIPPEE! Bat guano......all over the ground beneath the bat house.  I know it's the real thing because I Googled a picture of bat guano just to be sure.  Later in the evening I attended a meeting of our local chapter of the Audubon Society and was told it makes great fertilizer!  Oh...need to add "sorry" if you find this picture somewhat disgusting.
