A gorgeous little flycatcher of open habitats. Adult male is unmistakable: brilliant red below and dark above, with a dark mask. Females and immature males are much duller, but usually show reddish or yellowish on the lower belly and faint streaking on the white breast. Population in coastal Peru shows an unusually high number of uniformly chocolate-brown males; they usually show a faint hint of reddish on the belly. Widespread and fairly common in the proper habitat, from the southwestern U.S. to Argentina. Typically occurs singly or in pairs in open areas, including brushy grasslands and open riparian woodland. Often seen perched on fence posts along roadsides.
