Colorhamphus parvirostris

Tiny11 gForest

The Patagonian tyrant is 12 to 13 cm (4.7 to 5.1 in) long. The sexes have essentially the same plumage though females sometimes have a darker throat than males. Adults have a mostly gray head with a darker brownish gray crown and a blackish streak behind the eye. Their upperparts are olive-brown. Their wings are blackish brown with wide cinnamon edges on the coverts that show as two wing bars. Their tail is blackish brown. Their throat and underparts are grayish with a yellowish wash on the belly, flanks, and undertail coverts. They have a black iris, a black bill, and black legs and feet. Voice: The Patagonian tyrant's most frequently heard song is "a long, descending whistle, often repeated every three to four seconds", into which it sometimes mixes shorter whistles. It less often sings a "more complex vocalization containing three distinct phrases". Its calls are "variable, high-pitched, long and clear whistled notes" that are somewhat similar to the primary song.
