We were surprised to find Townsend's big-eared bat (Corynorhinus townsendii) up and around in November when the weather is cool.
Those magnificent ears are hard to mistake for any other species out here.
However, below 62 degrees F most big-ears are lethargic.
Maybe mild temperatures called them out of their caves.
December 1 was the last night a big-ear swooped into the recess.
(Pssst! Guess what? this one is a boy!)
