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.

Possible
About 20% of wildlife watchers report an Olivaceous Woodcreeper sighting in El Triunfo on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 93rd most-seen of the 221 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report an Olivaceous Woodcreeper in El Triunfo on a given day, against about 10% in March, May, August and October, the lowest months. That is one of El Triunfo's driest months, with about 15 mm of rain against 420 mm in June. June has too few records to rate.

Across all the parks we cover, that three-hour window holds the most Olivaceous Woodcreeper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Olivaceous Woodcreeper is recorded against all the birds logged in El Triunfo (33 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.
