For almost ten minutes, this Mockingbird was observing me as I photographed it. It occasionally reacted to the shutter sound of my camera. It then followed me down the trail for some distance.
I recently read an interesting article titled
"Mockingbirds Know Who You Are" on Discover Magazine. It turns out that they can pick out an intruder from a crowd, and defend themselves against only the intruder while leaving the nonthreatening people alone.
I'm happy that I was vetted as a friend.
