Cassin's Kingbird Facts, Pictures, Information

The Cassin’s is fairly wide-spread at center levels in the north western and west-central United States, where it overlaps substantially with the american kingbird. Monotypic. Length 8.4–9.2" (21–23 cm)

Identification Adult: dark-colored grey head and nape (mask less obvious); semi­concealed orange-red center title patch; dark-colored gray olive back, darkish wings. Dark grey torso differences with bright face, combinations to yellow-colored waist and olive flanks. Longest tail squared or a little bit notched; darkish dark-colored with an indistinct light grey terminal group. Relatively small expenses. Juvenile: identical but wings surrounded light sugar-cinnamon and light tail tip less apparent.

Similar Types The american has paler upperparts and chest; much less chin-breast contrast; and dark wings and dark-colored tail with bright external web of external feather pair (but be careful westerns completely missing external tail down or with worn-off external webs). The Cassin’s has light (but not genuine white) external web. The thick-billed, exotic, and Couch’s have paler or yellower chests, consistently darkish tails, and heavy bills; exotic and Couch’s also have paler supports and greatly notched tails.

Voice Call: single or recurring, strident kabeer; quickly recurring ki-dih or ki-dear. Beginning song: a recurring rruh rruh rruh-rruh rreahr, rruh ree reeuhr (possibly puzzled with the buff-collared nightjar’s).

Status and Submission Common. Breeding: open, older jungles, such as riparian, oak, and pinyon-juniper. Migration: relatively often discovered away from reproduction sites. In early spring, mid-March–early May, high April–May. In fall, travel overdue July–October, high July. Winter: american to central-southern South america Regionally person in seaside lower California. Vagrant: casual/accidental to Or, New york, Boston, Va, Illinois, La, and California.

Population Constant.
