Rare
Under 5% of wildlife watchers report a Black-winged Oriole sighting in Semuliki National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 213th most-seen of the 280 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.
December
In that month about 20% of wildlife watchers report a Black-winged Oriole in Semuliki National Park on a given day, against under 5% in January to November, the lowest months. That is one of Semuliki National Park's driest months, with about 40 mm of rain against 140 mm in May.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Black-winged Oriole sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 parks where we can rate Black-winged Oriole sightings, Semuliki National Park ranks 2nd at under 5%. The best odds are in Taï National Park (Ivory Coast, about 20%).
GBIF citizen-science records
It is estimated from how often the Black-winged Oriole is recorded against all the birds logged in Semuliki National Park (10 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.
