Tumbes Tyrant

The Tumbes tyrant is about 13.5 cm (5.3 in) long. The sexes have the same plumage. Adults have a dark gray crown, lores, and ear coverts. Their forecrown is bright yellow and fades to whitish along its supercilium. Their upperparts are gray or grayish olive. Their wings are mostly dusky black with white edges on the secondaries and tertials and white tips on the coverts; the last show as two wide wing bars. Their tail is mostly blackish with white edges on the outer feathers. Their throat and underparts are lemon yellow. They have a dark brown iris, a short black bill, and black legs and feet. Voice: What is thought to be the Tumbes tyrant's song is "a quiet, mellow rapid chatter, dyer'rYr'r, sometimes ending with a higher note, and occasionally interspersed with a shorter DEE'dew". Its calls are "a more emphatic, squeaky PSI'dyer'r'r'r and a clear, descending pew".
