Eastern Kingbird

Tyrannus tyrannus

A large dark flycatcher of fields and other open areas, the Eastern Kingbird is a common and widespread species. Despite its name, its range extends from the Atlantic to the Pacific coast.

Interesting Information

  • The Eastern Kingbird is highly aggressive toward nest predators and larger birds. Hawks and crows are attacked regularly. A kingbird was observed to knock a Blue Jay out of a tree and cause it to hide under bush to escape the attack.

  • During the summer the Eastern Kingbird eats mostly flying insects and maintains a breeding territory that it defends vigorously against all other kingbirds. In the winter along the Amazon, however, it has a completely different lifestyle: it travels in flocks and eats fruit.

  • Parent Eastern Kingbirds feed their young for about seven weeks. Because of this relatively long period of dependence, a pair generally raises only one brood of young per nesting season.
