Came across a blondish, small bat on the pavement around midnight. Possibly stunned from sudden cold front and wind blowing in from the ocean? We thought it was something else until it suddenly untucked its wings and flew off a little ways towards a building. Seemed to be ok, perhaps a little disoriented by the bright lights and sudden temp drop? Lots of cicada and moths around so could also have been feeding. Lovely looking bat. Looked tiny until it spread its wings. More golden than red to our eyes but it was dark out.

It appeared to be digging (?) down into the dirt by the rock cliff looking to sleep. We didn’t notice any dams within the 2 miles around it (although there has been dams in the past nearby), but we could’ve missed it. Seemed a bit of an odd situation and behavior. Hope it’s OK.
