Rare
Under 5% of wildlife watchers report a Sclater's Antwren sighting in Manu National Park on a given day, based on 129 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 352nd most-seen of the 641 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August and December–January
In those months about 10% of wildlife watchers report a Sclater's Antwren in Manu National Park on a given day, against under 5% in February–July and September–November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Sclater's Antwren 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 2 parks where we can rate Sclater's Antwren sightings, Manu National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Tambopata National Reserve (Peru, under 5%).

GBIF citizen-science records
It is estimated from how often the Sclater's Antwren is recorded against all the birds logged in Manu National Park (129 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.
