With luck
About 10% of wildlife watchers report a Black-nest Swiftlet sighting in Kuching on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 51st most-seen of the 57 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and November
In those months about 20% of wildlife watchers report a Black-nest Swiftlet in Kuching on a given day, against under 5% in January–April, June–August and October, the lowest months. December has too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Black-nest Swiftlet sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Black-nest Swiftlet sightings, Kuching ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Yogyakarta (Indonesia, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-nest Swiftlet is recorded against all the birds logged in Kuching (9 verified sightings), 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.
