The glossy swiftlet (Collocalia esculenta) is a species of swift in the family Apodidae. It is found on the Indonesian island of Sulawesi and eastwards to New Guinea, the Bismarck Archipelago and the Solomon Islands. The glossy swiftlet was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Hirundo esculenta. The type locality is Ambon Island, one of the Maluku Islands of Indonesia. The specific epithet esculenta is from esculentus the Latin word for "edible".

Possible
About 20% of wildlife watchers report a Glossy Swiftlet sighting in Makassar on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 66 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Glossy 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.
Only Makassar, in our data
Makassar is the only city on Wallace's Line with enough records to rate Glossy Swiftlet sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Apodidae
The closest relatives of the Glossy Swiftlet that you can see in Makassar (family Apodidae, Swifts) are Uniform Swiftlet (about 30%), Halmahera Swiftlet (about 20%) and House Swift (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Glossy Swiftlet is recorded against all the birds logged in Makassar (18 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.
