The Sulawesi hornbill (Rhabdotorrhinus exarhatus), also known as the Sulawesi tarictic hornbill, Temminck's hornbill or Sulawesi dwarf hornbill, is a relatively small, approximately 45 cm (18 in) long, black hornbill. The male has a yellow face and throat, and yellowish horn bill with black markings. The female has all-black plumage and a darker bill.
An Indonesian endemic, the Sulawesi hornbill is distributed in the tropical lowland, swamps and primary forests of Sulawesi and nearby islands, from sea level to altitude up to 1,100 metres. There are two subspecies of the Sulawesi hornbill.
Uncommon throughout its native range, the Sulawesi hornbill is evaluated as vulnerable on the IUCN Red List of Threatened Species. The species usually performs better in captivity than other species of hornbill. It is kept in multiple facilities across Europe, North America & Asia, including but not limited to Weltvogelpark Walsrode in Germany, Plzeň Zoo in the Czech Republic as well as San Diego Zoo...

Possible
About 30% of wildlife watchers report a Sulawesi Hornbill sighting in Tangkoko Nature Reserve on a given day, based on 338 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January–April and June
In those months about 40% of wildlife watchers report a Sulawesi Hornbill in Tangkoko Nature Reserve on a given day, against about 20% in October, the lowest month.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Sulawesi Hornbill sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate Sulawesi Hornbill sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sulawesi Hornbill is recorded against all the birds logged in Tangkoko Nature Reserve (338 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.
