About Anabazenops fuscus (Vieillot, 1816)
The white-collared foliage-gleaner, Anabazenops fuscus (Vieillot, 1816), is approximately 20 cm (7.9 in) long. It has a large, wedge-shaped bill, and males and females have identical plumage. Adults have a dark brown face with a distinct whitish supercilium, grayish white lores, and a white malar area. Their crown is a rich dark brown with a faint scalloped pattern. Their throat is white, and a wide white band circles their entire neck. Their back and rump are a lighter brown than the crown, while their uppertail coverts and tail are dark rufous. Their wings match the brown color of the back, and have a bright yellowish brown bend. Their upper breast is grayish buff with a tawny tinge that shifts to darker tawny-brown on the lower breast and belly. Their flanks and undertail coverts are darker and browner than the breast and belly. The iris is dark brown or dark reddish brown; the maxilla is dusky brown with a pale horn edge; the mandible is pale horn or pale gray; and the legs and feet are olive-gray, brownish gray, or dark olive-brown. Juveniles resemble adults, but have a tawny-buff tinge on the supercilium and underparts. This species is found in southeastern Brazil, ranging from Bahia and Minas Gerais south to Santa Catarina. It inhabits primary and secondary montane evergreen forest, and is closely associated with large, thick bamboo thickets. It occurs at elevations between 350 and 1,200 m (1,100 and 3,900 ft).
