About Grallaria flavotincta P.L.Sclater, 1877
Grallaria, the antpitta genus, is a distinct group of plump, round antbirds whose feathers are often fluffed, and members have stout bills and very short tails. The yellow-breasted antpitta, Grallaria flavotincta, measures 17 to 18 cm (6.7 to 7.1 in) in length; one recorded individual weighed 63 g (2.2 oz). This species has identical plumage in both sexes. Adult yellow-breasted antpittas have a dusky gray forecrown and lores, with pale bluish-white or grayish-white bare skin surrounding the eye. Their crown, back, rump, wings, and tail are solid unmarked rufous brown. Most of their underparts are white with a prominent yellow wash; this yellow is darkest on the throat and upper breast, and fades to white on the sides, flanks, and lower belly. The rufous brown of the upperparts extends irregularly onto the sides, flanks, and crissum. Adult males and females share the same soft part coloration: a dark brown iris, a black bill, and bluish gray legs and feet. Juveniles have an almost entirely dark gray head, with bare yellowish to orangish yellow skin around the eye. Their upperparts match adult coloration, with the addition of some irregular dark gray patches. A juvenile's throat is mostly gray, with only a faint trace of yellow. The rest of a juvenile's underparts are mottled yellow and gray, with some chestnut brown splotches. Juveniles have a dusky gray maxilla with a slightly paler tip, a bright orange mandible, and pinkish gray to pinkish blue legs and feet. The yellow-breasted antpitta is distributed along the Pacific slope of the Andes, ranging from Antioquia Department in northwestern Colombia south to Pichincha Province in northwestern Ecuador. It primarily lives in the interior understory of humid montane forest, where it prefers steep slopes and areas alongside watercourses in ravines. It can also be found at forest edges. Its elevational range is 1,300 to 2,100 m (4,300 to 6,900 ft) in Colombia, and 1,500 to 2,350 m (4,900 to 7,700 ft) in Ecuador.
