Fulvous-crowned Scrub Tyrant

The fulvous-crowned scrub tyrant is 9 to 12 cm (3.5 to 4.7 in) long and weighs 5 to 10 g (0.18 to 0.35 oz). The sexes have the same plumage. Adults of the nominate subspecies have a drab brownish crown with a weak crest and rufous central crown feathers that are somewhat hidden. They have dull buffy to whitish lores and an indistinct dull buffy to whitish eye-ring on an otherwise buffy brown face. Their upperparts are drab brownish. Their wings are dusky brown with rufous tips on the coverts and less distinct rufous edges on the flight feathers. Their tail is dusky. Voice: The fulvous-crowned scrub tyrant is a "distinctively noisy species...more likely to be heard than seen". Its "advertising song" is "a dry, scratchy, unmusical, ca. 1-second, plee-plit-irick endlessly repeated, sometimes with several introductory plee or chee oo notes before the staccato portion, and the first syllable grating".
