This spot is a favorite for many of the birds. This juvenile Orange-crowned Warbler seemed kind of perplexed to find this Yellow Warbler there ahead of him.
After this shot he turned to the side and opened his mouth as if calling for Mom. Then the Yellow Warbler looked up and opened it's mouth as if telling it to stow it.
I know, don't anthropomorphize, but why not, it's as good an entertainment as any.
