"Chick-a-dee-dee-dee!" The little bird repeated his namesake call angrily. I couldn't blame him for being upset. At the time, I was accompanied by a large predator perched on my glove. Carson the Red-tailed Hawk had been soaking in some sun, but she came on alert with the chickadee's chatters. That call, so familiar to most people, is also recognized by other chickadees, nuthatches, and other small birds (including tropical birds that don't naturally live with chickadees!) to mean "watch out for danger!" Nearby birds will flock to the "chick-a-dee" alarm, ready to help chase away a predator. This little chickadee didn't know that Carson already had her breakfast and posed no threat to the backyard birds. Carson kept a careful eye on the situation while I unlocked the mew door. We went back inside before the mob could chase us away!
