Pale-browed Treehunter

The pale-browed treehunter (Cichlocolaptes leucophrus) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to Brazil. == Taxonomy and systematics == The pale-browed treehunter's taxonomy is unsettled. The South American Classification Committee of the American Ornithological Society, the International Ornithological Committee, and the Clements taxonomy treat it as a species with two subspecies, the nominate C. l. leucophrus (Jardine & Selby, 1830) and C. l. holti (Pinto, 1941). BirdLife International's Handbook of the Birds of the World (HBW) treats the two taxa as separate species, the large and small pale-browed treehunters respectively. The pale-browed treehunter shares genus Cichlocolaptes with the cryptic treehunter (C. mazarbarnetti), which is believed to be extinct. This article follows the one-species two-subspecies model. == Description == The nominate subspecies of the pale-browed treehunter is about 22 cm (8.7 in) long; subspecies C. l. holti is about 18 cm (7.1 in) long. Both subspecies have a long dagger-like bill, and male and female plumages are alike. Adults of the nominate subspecies have a buffish white supercilium, blackish and dull buff lores, and a dark brown band behind the eye on an otherwise duff buff face. Their crown is dark…
