About Pyrocephalus rubinus (Boddaert, 1783)
The scarlet flycatcher, Pyrocephalus rubinus, measures approximately 14 cm (5.5 in) in length and weighs between 12 and 15 g (0.42 to 0.53 oz). Adult males have an intense poppy red forehead and crown that extends down to the eyes. Their lores and ear coverts are dark grayish brown, forming a distinct "mask". Their nape, upperparts, and tail are blackish, while their rump is blackish brown. Their wings are blackish, with paler edges along the coverts and tertials. The lower face, throat, and underparts are a slightly lighter poppy red than the crown, and sometimes have an orange tinge. Adult females have a grayish brown head with grayish lores and an indistinct whitish supercilium. Their back and rump match the grayish brown of the head, while their uppertail coverts and tail are a duskier grayish brown. Their wings are mostly a darker grayish brown than the back. Their throat and underparts are dull white with grayish brown streaks across the entire area, and sometimes have a pale yellow tinge on the belly. Both sexes have a dark brown iris, a brownish black bill, and blackish to brownish black legs and feet. The scarlet flycatcher is found year-round from southeastern Colombia east across central Brazil, and south from there through eastern Ecuador, eastern Peru, eastern Bolivia, and southern Brazil into northern Argentina, Paraguay, and Uruguay. It lives in semi-open to open landscapes, including open woodland, the edges of denser woodlands, pastures with scattered trees, and agricultural areas.
