Cassin's Kingbird - Tyrannus vociferansCassin's Kingbird is very similar to the Western Kingbird and overlaps in range with it, but is found in more wooded habitats than it's close cousin.  Their scientific name "vociferans" comes from their noisy, repetitive morning song.

Diet: Primarily feeds on berries.  Will also feed on fruits and berries, more so than most of the flycatchers.

Behavior: Forages by flying out from a perch to capture flying insects.  They will also hover and glean insects from foliage and branches.

Nesting: Mid-May through mid-July

Song: Song is an exuberant kideer-kideer-kideer. 

Migration: Summers in portions of the interior West.  Winters in Mexico and southward.
