With luck
About 10% of wildlife watchers report a Dusky Crimson-wing sighting in Volcanoes National Park on a given day, based on 72 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 65th most-seen of the 156 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July and August
In those months about 30% of wildlife watchers report a Dusky Crimson-wing in Volcanoes National Park on a given day, against about 10% in October to June, the lowest months. Those are among Volcanoes National Park's driest months, with about 30 mm of rain a month against 250 mm in April.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Dusky Crimson-wing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate Dusky Crimson-wing sightings, Volcanoes National Park ranks 3rd at about 10%. The best odds are in Nyungwe National Park (Rwanda, about 20%) and Bwindi Impenetrable National Park (Uganda, about 10%).
GBIF citizen-science records
It is estimated from how often the Dusky Crimson-wing is recorded against all the birds logged in Volcanoes National Park (72 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.
