Cassin's Kingbird

Overview

Cassin's kingbird (Tyrannus vociferans) is a large tyrant flycatcher native to western North America, with a name commemorating the American ornithologist John Cassin. It is currently listed as Least Concern on the IUCN Red List.

Identification

• Gray head with slightly darker cheeks, a pale throat, and deep yellow lower breast.
• Gray-olive underparts and a dark, unforked tail with a buffy fringe; the distal end of the tail feathers has a thin white edge.
• Length of 8.3–9.1 in (21–23 cm) with a wingspan of 41 cm and a weight of 1.6 oz (45 g).
• Call sounds like 'chi-beer', consisting of a high-pitched shorter chirp followed by a longer one.

Habitat

In summer, this species inhabits rangelands and savannas in California, from Montana to Utah, and along the eastern Rocky Mountains. It migrates to winter quarters in southern California and northern Central America, though it is a permanent resident in south-central Mexico.

Diet

It primarily feeds on insects caught by hawking from high perches, supplementing its diet with smaller amounts of berries and fruits.
