The plume-toed swiftlet (Collocalia affinis) is a small bird in the swift family Apodidae. It is found on some eastern Indian Ocean islands, the Malay Peninsula, Sumatra, and lowland Borneo. Its natural habitat is subtropical or tropical moist lowland forests. It was previously considered a subspecies of the glossy swiftlet.
The plume-toed swiftlet was described by the English ornithologist Robert Cecil Beavan in 1867 and given current binomial name Collocalia affinis. The type locality is Port Blair in the Andaman Islands. The specific epithet affinis is Latin for "related" or "applied". The plume-toed swiftlet was previously treated as a subspecies of the glossy swiftlet but was promoted to species status based on the results of a detailed analysis of the swiftlets in the genus Collocalia published in 2017.

Rare
Under 5% of wildlife watchers report a Plume-toed Swiftlet sighting in Kuala Lumpur on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 124th most-seen of the 228 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Plume-toed Swiftlet in Kuala Lumpur on a given day, so our monthly data shows no clear season.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Plume-toed Swiftlet sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
5th of 5
Of the 5 cities where we can rate Plume-toed Swiftlet sightings, Kuala Lumpur ranks 5th at under 5%. The best odds are in Kuching (Malaysia, about 40%), Padang (Indonesia, about 40%) and Singapore (Singapore, about 10%).
Same family: Apodidae

GBIF citizen-science records
It is estimated from how often the Plume-toed Swiftlet is recorded against all the birds logged in Kuala Lumpur (58 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.
