The Moluccan swiftlet (Aerodramus infuscatus) is a small bird in the swift family Apodidae that is found on Sulawesi and on the Maluku Islands in Indonesia. Two subspecies, the Sulawesi swiftlet and the Seram swiftlet, have sometimes been considered as separate species.
The Moluccan swiftlet was formally described in 1880 by the Italian zoologist Tommaso Salvadori under the binomial name Collocalia infuscata based on a specimen collected on the island of Ternate in the Maluku Islands. The specific epithet infuscata is Latin meaning "dusky" from infuscare meaning "to make dark". The Moluccan swiftlet is now one of 25 swiflets placed in the genus Aerodramus that was introduced in 1906 by the American ornithologist Harry C. Oberholser. Wikipedia →

Likely
About 40% of wildlife watchers report a Halmahera Swiftlet sighting in Tangkoko Nature Reserve on a given day, based on 384 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 60% of wildlife watchers report a Halmahera Swiftlet in Tangkoko Nature Reserve on a given day, against about 10% in January, the lowest month.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Halmahera 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.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate Halmahera Swiftlet sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Halmahera Swiftlet is recorded against all the birds logged in Tangkoko Nature Reserve (384 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.
