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 30% of wildlife watchers report an Olivaceous Woodcreeper sighting in Main Ridge Forest Reserve on a given day, based on 288 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report an Olivaceous Woodcreeper in Main Ridge Forest Reserve on a given day, against about 10% in June, the lowest month. That is one of Main Ridge Forest Reserve's driest months, with about 65 mm of rain against 230 mm in October.
Between 8 and 11 am
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.
5th of 52
Of the 52 parks where we can rate Olivaceous Woodcreeper sightings, Main Ridge Forest Reserve ranks 5th at about 30%. The best odds are in Serra dos Órgãos National Park (Brazil, about 60%), Itatiaia National Park (Brazil, about 50%) and Amboró National Park (Bolivia, about 50%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the Olivaceous Woodcreeper is recorded against all the birds logged in Main Ridge Forest Reserve (288 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.
