Eastern Kingbirds
Tyrant Flycatchers ... Kingbirds
Distribution / Habitat:
The Eastern Kingbird, Tyrannus tyrannus - a large Tyrant flycatcher - can be found in the open areas across North America and migrate in flocks to South America.
Nesting / Breeding:
They make a sturdy cup nest in a tree or shrub, sometimes on top of a stump or pole. These birds aggressively defend their territory, even against much larger birds.
Some Eastern Kingbirds place their nests in the open while others hide nests very well. It has been shown that those pairs that hide their nests well tend to be less aggressive towards intruders near the nest (perhaps relying on nest cover), while pairs that nest in the open tend to be more overtly aggressive to intruders. Both male and female participate in nest defence, but females may stay on well-hidden nests longer than females with open nests who may leave nests earlier to chase away predators. Those pairs nesting in the open may be able to see predators coming earlier and rely on aggressive behaviour to protect their young. The aggressive behaviour of Eastern Kingbirds has been shown to keep ravens and crows from finding experimental nests placed near kingbird nests. Similar experimental nests placed far from the kingbird nests were found far more often by crows and ravens.
Eastern Kingbirds in Southern British Columbia can nest in open fields; in shrubs over open water; high in tall trees and even in the tops of small stumps.
These birds remove cowbird eggs from their nests.
Identification Tips:
- Length: 6.75 inches

Adult:
- Black tail with white terminal band
- Blackish upperparts
- Whitish underparts
- Red crown patch rarely visible
Juvenile:
- Upperparts browner than adult
