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.

Likely
About 40% of wildlife watchers report a White-nest Swiftlet sighting in Yangon on a given day, based on 90 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 66 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
May to July
In those months about 50% of wildlife watchers report a White-nest Swiftlet in Yangon on a given day, against about 30% in February–March, August and October–December, the lowest months. Those are among Yangon's wettest months, with about 210 mm of rain a month against almost none in February. April has too few records to rate.
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.
6th of 14
Of the 14 cities where we can rate White-nest Swiftlet sightings, Yangon ranks 6th at about 40%. The best odds are in Đà Nẵng (Vietnam, about 90%), Phnom Penh (Cambodia, about 80%) and Ho Chi Minh City (Vietnam, about 70%).
Same family: Apodidae
The closest relatives of the White-nest Swiftlet that you can see in Yangon (family Apodidae, Swifts) are Asian Palm-Swift (about 60%) and House Swift (about 10%), 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 Yangon (90 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.
