Rare
Under 5% of wildlife watchers report a Rusty-breasted Cuckoo sighting in Sepilok on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 175th most-seen of the 242 birds we can rate there. Over three days the chance rises to under 5%, and over a week 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 a Rusty-breasted Cuckoo in Sepilok 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 Rusty-breasted Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 21
Of the 21 parks where we can rate Rusty-breasted Cuckoo sightings, Sepilok ranks 17th at under 5%. The best odds are in Kakadu National Park (Australia, about 20%), Raja Ampat (Indonesia, about 20%) and Daintree National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Rusty-breasted Cuckoo is recorded against all the birds logged in Sepilok (27 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.
