The olivaceous woodcreeper (Sittasomus griseicapillus) is a passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found from central Mexico south through every Central American country, on the island of Tobago, and in every mainland South American country except Chile, French Guiana, and Suriname.
The olivaceous woodcreeper is the only member of genus Sittasomus. However, taxonomic systems vary in their treatment of the taxon, with some splitting it into two species. The International Ornithological Committee and the Clements taxonomy assign these 15 subspecies to the olivaceous woodcreeper; Clements distributes them among five groups.

GBIF citizen-science records
It is estimated from how often the Olivaceous Woodcreeper is recorded against all the birds logged in Rio de Janeiro (132 verified sightings), 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.
