Remarkably, roosting right above a well-traveled path in a hummingbird garden. Arboretum staff seemed to indicate that it wasn't that unusual.

MURCIELAGO SIN IDENTIFICAR

This bat perched daily on the same tree 2-3 M above ground from October 14 through 26 Mar 15. It has not been seen since. A hoary bat, presumed to be same individual, was discovered in February 2014 on the same tree mentioned above (Monterey Pine, Pinus radiata) and was seen daily until leaving in late March. We will now be looking for it this fall. Should be very interesting to see it return yet again, likely for its third winter, to the very same tree?! Shall see.
If same individual, first spotted February 2014 in same area of deeply furrowed bark on same Monterey Pine (Pinus radiata). Absent during spring and summer returning prior to October 10, 2014 to same spot!!
More photos available.
I'm not totally familiar with bats. I believe this is the right ID. It was found dead on the sidewalk. I put my foot right next to it for size comparison. I wear a size 10 in men's.
