Diard's trogon (Harpactes diardii) is a species of bird in the family Trogonidae. It is found in Brunei, Indonesia, Malaysia, Singapore, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests.
It is threatened by habitat loss. Apalodermatinae is the African subfamily consisting of one genus, Apaloderma. The Asian subfamily is Harpactinae and contains two genera, Harpactes and Apalharpactes. Males are black headed and breasted with a pink breast line. Females are brown headed and breasted with pink under parts. Diard's trogon eats caterpillars, beetles, stick-insects, locustids and other Orthoptera, and fruits. The breeding times of Diard's trogon range from February to August: February to mid-May in Malaysia, Mid-May to August in Borneo.
The Dayak Iban community believes that hearing the Diard's trogon's call is a bad omen. The trogons are birds with colorful plumage that belong to the order Trogoniformes which only comprises one family, the Trogonidae. The genus Harpactes, which is one of the seven genera contained in this family, are all residents of South and Southeast Asia. Two biogeographical hypotheses propose different origins of trogons...

Possible
About 30% of wildlife watchers report a Diard's Trogon sighting in Way Kambas National Park on a given day, based on 82 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th most-seen of the 205 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Diard's Trogon in Way Kambas National Park on a given day, against about 20% in April, August and October, the lowest months. November to February have too few records to rate.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Diard's Trogon sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Among the best
Of the 8 parks where we can rate Diard's Trogon sightings, Way Kambas National Park ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Sepilok (Malaysia, about 30%).
Same genus: Harpactes
The closest relatives of the Diard's Trogon that you can see in Way Kambas National Park (genus Harpactes, Asian Trogons) are Scarlet-rumped Trogon (about 30%) and Red-naped Trogon (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Diard's Trogon is recorded against all the birds logged in Way Kambas National Park (82 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.
