Rare
Under 5% of wildlife watchers report a Ruddy Spinetail sighting in Manu National Park on a given day, based on 44 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 454th most-seen of the 641 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.
January
In that month about 10% of wildlife watchers report a Ruddy Spinetail in Manu National Park on a given day, against under 5% in February to December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ruddy Spinetail sightings with a recorded time, and about 7 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 Ruddy Spinetail 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 Ruddy Spinetail is recorded against all the birds logged in Manu National Park (44 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.
