Rare
Under 5% of wildlife watchers report a White-browed Crombec sighting in Volcanoes National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 97th most-seen of the 156 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.
January and June–September
In those months about 10% of wildlife watchers report a White-browed Crombec in Volcanoes National Park on a given day, against under 5% in February–May and October–December, the lowest months. Those are among Volcanoes National Park's driest months, with about 70 mm of rain a month against 250 mm in April.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-browed Crombec sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 6
Of the 6 parks where we can rate White-browed Crombec sightings, Volcanoes National Park ranks 3rd at under 5%. The best odds are in Bwindi Impenetrable National Park (Uganda, about 20%) and Nyungwe National Park (Rwanda, about 10%).
GBIF citizen-science records
It is estimated from how often the White-browed Crombec is recorded against all the birds logged in Volcanoes National Park (24 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.
