Black-throated Green Warbler
This handsome bird varies in appearance: Males have an olive head and back with a black throat and chest, while females and young birds have lesser degrees of black coloration. Nesting from the elevated Cumberland Plateau eastward, during migration they may easily be seen seeking insects in low trees and shrubs. In cooler weather, feeds on poison ivy berries and other small fruits. The song is a buzzy “zoo-zee-zoo-zoo zee”.
