Scale-crested Pygmy Tyrant

The scale-crested pygmy tyrant is 8 to 10 cm (3.1 to 3.9 in) long and weighs about 7 to 8 g (0.25 to 0.28 oz). It has long crown feathers that form the eponymous crest and that it sometimes erects and fans. Females have a smaller crest than males but the sexes otherwise have the same plumage. Adults of the nominate subspecies L. p. pileatus have a black crest with rufous edges on the feathers. They have whitish lores on an otherwise brownish face. Their back, rump, and uppertail coverts are olive. Voice: The scale-crested pygmy tyrant's main vocalization is a very loud trill that differs somewhat geographically. It has been written as "tr-tr-tr-tr-tr-tr-tr-tr" and "trrrrrreét", "dzzeeer-dzeer-dzeer", and "cre'e'e'e'e, k'e'e'e'e". It also makes "a series of sharp "preek" notes, sometimes widely spaced".
