Sepia-brown wren, Peruvian wren, and fulvous wren (C. fulva) form a superspecies.
Usually "daughter" species resulting from splits do not retain the "parent's" English name. That is why the South American Classification Committee of the American Ornithological Society (SACC/AOS) and the Clements taxonomy call C. olivascens Sharpe's wren. That common name commemorates the British zoologist Richard Bowdler Sharpe.
The sepia-brown wren has two subspecies, the nominate Cinnicerthia olivascens olivascens and C. o. bogotensis. The sepia-brown wren is 16 cm (6.3 in) long; males weigh an average of 25.9 g (0.91 oz) and females weigh an average of 23 g (0.81 oz). Both subspecies are shades of brown. The nominate adult has a grayish brown crown, reddish brown back and rump, and a chesnut tail with blackish bars. It has a... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sharpe's Wren sighting in Los Nevados National Natural Park on a given day, based on 212 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 177th most-seen of the 424 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, April–May and July
In those months about 10% of wildlife watchers report a Sharpe's Wren in Los Nevados National Natural Park on a given day, against under 5% in March, June and August–January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Sharpe's Wren sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Sharpe's Wren sightings, Los Nevados National Natural Park has the highest daily chance: under 5%. Next come Podocarpus National Park (Ecuador, under 5%) and Farallones de Cali National Natural Park (Colombia, under 5%).
GBIF citizen-science records
It is estimated from how often the Sharpe's Wren is recorded against all the birds logged in Los Nevados National Natural Park (212 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.
