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 Podocarpus National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 330th most-seen of the 446 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sharpe's Wren in Podocarpus National Park on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 3 parks where we can rate Sharpe's Wren sightings, Podocarpus National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Los Nevados 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 Podocarpus National Park (18 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.
