The sandstone cave yielded 602 photos, but only 274 were of animals.
The low success rate of 46% was due to false triggers caused by bats.
They zipped in and out of the cave seeking a place to settle, and this triggered the camera.
Even so, we got 117 bat photos, and this yellowish brown bat with biggish ears was the most commonly photographed species.
Two species fit the bill -- the big-eared myotis (Myotic evotis) and the fringed myotis (M. thrysanodes).
The distinguishing characteristic, a fringe of hair along the interfemoral membrane would make it the latter.
None of the photos is clear enough to see it.
I am not confident of this identification, so this is a call to any mammalogists out there to speak up.
