Black phoebe

Appearance

The black phoebe is a medium-sized flycatcher, being 16 cm in length and weighing 15 to 22 g. It has predominantly black plumage, with white on its belly and undertail coverts. The white forms an inverted "V" in the lower breast. The sexes are identical and plumage does not vary seasonally. Juveniles have browner plumage, cinnamon-brown feather tips on their body, and brown wing-bars. The bird has brown irises and black legs, feet, and beak.

The phoebe can be recognized by a characteristic "tail-wagging" motion, in which the tail is lowered and the tail's feathers fanned out. It accomplishes almost all locomotion by flight, which is direct, with steady wing beats. Its song consists of two alternating phrases. The song can be heard from both sexes, but is more commonly sung by males.

Naming

Six subspecies are commonly recognized, although two are occasionally combined as a separate species, the white-winged phoebe.

Distribution

The black phoebe breeds in the west and southwest United States, Mexico and Central America, and parts of South America. In Oregon it is found in river valleys on the Pacific coast, and in California on the western side of Coast Ranges. It breeds throughout the Colorado River valley and occasionally is found to the north in southern Nevada and southwestern Utah, as well as Arizona and central New Mexico. In Central America it breeds on Baja California, except for the central part of the peninsula, and on interior mainland Mexico southwest to Panama, excluding El Salvador. In South America it is found in the coastal mountains of Venezuela, through Colombia, Ecuador, and Peru, to western Bolivia and northwestern Argentina.

It lives year-round in most of its range and is more sedentary than either of the other phoebes in its genus, although northern populations may be partially migratory. It is always found near water and is often found at coastal cliffs, river/lake banks, or even park fountains. Habitats must also include a supply of mud for nest building, and the birds' specialized nesting requirements probably cause their somewhat irregular range.
