I often hear Spotted Towhees, but getting a good shot of them is usually tough. They like to hide in the center of trees or, when on the ground, they scoot deep under bushes. I managed to get lucky one day last year and get these few shots.
Their red eyes are particularly striking.
I found this guy by listening for his call...
...it's one of the few that I have learned to identify by ear.
He gave me one last look at those crazy eyes and then he was gone.
