With dark gray upperparts and a neat white tip to the tail, the Eastern Kingbird looks like it’s wearing a business suit. And this big-headed, broad-shouldered bird does mean business—just watch one harassing crows, Red-tailed Hawks, Great Blue Herons, and other birds that pass over its territory. Eastern Kingbirds often perch on wires in open areas and either sally out for flying insects or flutter slowly over the tops of grasses. They spend winters in South American forests, where they eat mainly fruit.
