The edible-nest swiftlet (Aerodramus fuciphagus), also known as the white-nest swiftlet, is a small bird of the swift family which is found in Southeast Asia. Its opaque and whitish nest is made exclusively of solidified saliva and is the main ingredient of bird's nest soup, a delicacy of Chinese cuisine. Germain's swiftlet (Aerodramus germani) is now treated as conspecific with this species.
The edible-nest swiftlet was formally described in 1812 by the Swedish naturalist Carl Peter Thunberg under the binomial name Hirundo fuciphaga based on a specimen collected on the island of Java. The specific epithet fuciphaga combines the Ancient Greek φυκος/phukos meaning "seaweed" with -φαγος/-phagos meaning "-eating". The edible-nest swiftlet is now one of 25 swiftlets placed in the genus Aerodramus that was introduced in 1906 by the American ornithologist Harry C. Oberholser.

Rare
Under 5% of wildlife watchers report a White-nest Swiftlet sighting in Tangkoko Nature Reserve on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 118th most-seen of the 138 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.
December
In that month about 10% of wildlife watchers report a White-nest Swiftlet in Tangkoko Nature Reserve on a given day, against under 5% in January to November, the lowest months.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most White-nest Swiftlet sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
17th of 19
Of the 19 parks where we can rate White-nest Swiftlet sightings, Tangkoko Nature Reserve ranks 17th at under 5%. The best odds are in Cat Tien National Park (Vietnam, about 60%), Khao Luang National Park (Thailand, about 50%) and Khao Sok National Park (Thailand, about 40%). All parks ranked.
Same genus: Aerodramus
The closest relatives of the White-nest Swiftlet that you can see in Tangkoko Nature Reserve (genus Aerodramus, Dark Swiftlets) are Halmahera Swiftlet (about 40%) and Uniform Swiftlet (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-nest Swiftlet is recorded against all the birds logged in Tangkoko Nature Reserve (19 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.
