The sharp-billed treehunter (Heliobletus contaminatus), sometimes called the sharp-billed xenops, is a species of
Taxonomy and systematics
The sharp-billed treehunter is assigned two subspecies, the
One author included genus Heliobletus within Xenops, as the sharp-billed treehunter's plumage is very similar to those of some Xenops species. Genetic data refute this treatment and find that it belongs in Heliobletus and is
The sharp-billed treehunter is the only member of genus Heliobletus.[2] However, one author states that "[a]n undescribed ''Heliobletus sp. occurs in SE Bahia [Brazil]".[8]
Description
The sharp-billed treehunter is 12 to 13 cm (4.7 to 5.1 in) long and weighs 13 to 15 g (0.46 to 0.53 oz). It has a short, pointed, and slightly downturned bill, and male and female plumages are alike. Adults of the nominate subspecies have a wide golden-buff

The nominate subspecies of the sharp-billed treehunter is found in southeastern Brazil from Minas Gerais and Espírito Santo south to São Paulo and Rio de Janeiro states. H. c. camargoi is found from São Paulo south through Rio Grande do Sul and eastern Paraguay into northeastern Argentina's Misiones Province and extreme northeastern Uruguay. The species inhabits humid lowland and montane evergreen forest. In elevation it ranges from sea level to 1,830 m (6,000 ft).[5] The nominate subspecies tends to be more numerous at the higher elevations.[8]
