With luck
About 10% of wildlife watchers report a Black Coucal sighting in Serengeti National Park on a given day, based on 173 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 221st most-seen of the 469 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
December to May
In those months about 10% of wildlife watchers report a Black Coucal in Serengeti National Park on a given day, against under 5% in June to November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black Coucal 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 14
Of the 14 parks where we can rate Black Coucal sightings, Serengeti National Park ranks 3rd at about 10%. The best odds are in Kidepo Valley National Park (Uganda, about 20%) and Ruaha National Park (Tanzania, about 10%).
GBIF citizen-science records
It is estimated from how often the Black Coucal is recorded against all the birds logged in Serengeti National Park (173 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.
