The sharp-billed treehunter (Heliobletus contaminatus), sometimes called the sharp-billed xenops, is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Brazil, Paraguay, and Uruguay.
However, there is some confusion about the subspecific epithets of the subspecies, and one or both might be changed. In recognition of that possibility, BirdLife International's Handbook of the Birds of the World gives H. c. camargoi the trinomial "Heliobletus contaminatus [new name]".
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 sister to genus Philydor.
The sharp-billed treehunter is the only member of genus Heliobletus. However, one author states that "[a]n undescribed ''Heliobletus sp. occurs in SE Bahia [Brazil]". Recordings of this undescribed taxon have been made... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Sharp-billed Treehunter is recorded against all the birds logged in Serra dos Órgãos National Park (24 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
