I originally thought it was an Antrozous pallidus (Pallid Bat), but the ears aren't long enough. The overall bat size is a bit too big to be a local myotis species. Any thoughts on the ID?
Here are my observations about its physical characteristics:
Head and body 66 mm
Tail 33 mm
Nose to tail 99 mm
No keeled calcar
No "free-tail", tail extends to tip of membrane
Forearm length 2-1/4 inch
Ears 20 mm
Flat, forward-pointing ears. Not pointed at the end.
No hair on feet
No nose leaf
Nostrils distinct but maybe not "pig-like".
Dorsal fur: pale at roots, tipped brown
Ventral fur: white
No yellow colors
Light-colored ears and face
Found dead, no "white nose" fungus observed.
My student Hailey Williams brought this in. She has several bats roosting in her neighborhood.
NOTE: My measurements weren't exactly lined up in the photos (also, the wing was not fully stretched out).
Boggs state forest. Base of tree stump adjacent to Gales trail at the trail's highest elevation. Flat terrain in general location, no slope. Not heavily forested, sparse trees (ie ponderosa pine). Appears similar to the "badger den" at Pepperwood Preserve in terms of entrance size and shape. Didn't look like a burned out tree root to me, too distinct. I can see up four feet of den length with no terminal.
