Rare
Under 5% of wildlife watchers report a Mossy-nest Swiftlet sighting in Sepilok on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 226th most-seen of the 242 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mossy-nest Swiftlet in Sepilok on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Mossy-nest Swiftlet sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Mossy-nest Swiftlet sightings, Sepilok ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Kinabatangan Wildlife Sanctuary (Malaysia, under 5%).
GBIF citizen-science records
It is estimated from how often the Mossy-nest Swiftlet is recorded against all the birds logged in Sepilok (8 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.
