Sarah Safranek and I noticed a small brown bat flying low over the water about half a mile south of the Stan Sayres hydroplane pits on Lake Washingtion about 4 PM yesterday afternoon. The bat spent about 15-20 minutes making rough circles near the lake shore, occasionally dipping down to touch the surface, and then flew inland towards a grove of trees. The air was still and the temperature was about 52 degrees.
I read that Little Brown Bats will commonly interrupt their hibernation after a few weeks and fly around for a while on warm winter's evenings. I imagine that was what we witnessed. I also read that these flights use about three-fourths of their stored fat reserves.
