7/7/11 Baja California Tree Frog (Pseudacris hypochondriaca).
I was working on the computer in my office on the evening of July 7th, 2011, when I saw something move outside on the window ledge. Who was that froggy in the window? A Baja California Tree Frog, methinks. The dark stripe through the eye seems indicative (California tree frogs lack the stripe, and Pacific tree frogs don't occur this far south). Inhabits forest, woodland, chaparral, grasslands, desert oases, urban areas, and pastures, throughout Southern California. These are the frogs that emit that well-known "ribit ribit" sound. Size was about 1 1/2" and apparently he can scale walls!
