Laura Erickson's For the Birds

Tyrannus tyrannus lives up to its scientific name, chasing and dive-bombing perceived enemies as large as Bald Eagles until they turn tail. A feisty, extremely territorial insectivore all summer, it transforms into a sociable frugivore when it reaches its South American wintering range.

Eastern Kingbirds have a distinctive flight pattern, their wingbeats rapid and shallow. The tail’s white terminal band is also distinctive.
