Descripción

Photographed on US Forest Service land in the Laguna Mountains east of San Diego. This site features a small concrete cattle trough that bats of a variety of species come to for nightly drinks. Corynorhinus townsendii is designated a California Department of Wildlife species of special concern.

The first image was taken at 11:38 pm and the second at 12:45 am. I was not able to determine if they were the same individual, possibly not. I monitored bat activity at this site acoustically and with a night vision monocular (ITT Night Enforcer 160 3rd Generation night vision monocular).

The third image is a screen shot of a sonogram of a COTO's ultrasonic echolocation calls recorded adjacent to the water source at 12:14 am, approximately half way between the two photographs. The recording was made using a Wildlife Acoustics Echo Meter Touch 2 microphone attached to an iPad Mini4 table running the Echometer Touch application. It was post-processed in Kaleidoscope Pro software on a Windows 10 laptop.
