Rare
Under 5% of wildlife watchers report an Olive Long-tailed Cuckoo sighting in Bwindi Impenetrable National Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 254th most-seen of the 400 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Olive Long-tailed Cuckoo in Bwindi Impenetrable National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Olive Long-tailed Cuckoo sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Bwindi Impenetrable National Park, in our data
Bwindi Impenetrable National Park is the only park on Wallace's Line with enough records to rate Olive Long-tailed Cuckoo sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Cercococcyx
The closest relatives of the Olive Long-tailed Cuckoo that you can see in Bwindi Impenetrable National Park (genus Cercococcyx, African Long-tailed Cuckoos) are Dusky Long-tailed Cuckoo (about 20%) and Barred Long-tailed Cuckoo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Olive Long-tailed Cuckoo is recorded against all the birds logged in Bwindi Impenetrable National Park (31 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.
