Bluethroat
Hum a few notes and these handsome Arctic birds might mimic you, like a mockingbird or catbird. They also migrate back and forth between the Old and New Worlds, Senner said.
The bird is named for the male’s blue throat, which can have a white or red center. Though colorful, the guarded bluethroat is hard to spot in dense vegetation. “It is easy to see only while it is singing or performing flight displays,” states the Cornell Lab guide.
