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...

Rare
Under 5% of wildlife watchers report a Diard's Trogon sighting in Khao Luang National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 153rd most-seen of the 215 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January, March and July
In those months about 10% of wildlife watchers report a Diard's Trogon in Khao Luang National Park on a given day, against under 5% in February, April–June and August–December, the lowest months.
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.
5th of 8
Of the 8 parks where we can rate Diard's Trogon sightings, Khao Luang National Park ranks 5th at under 5%. The best odds are in Sepilok (Malaysia, about 30%), Way Kambas National Park (Indonesia, about 30%) and Danum Valley Conservation Area (Malaysia, about 20%).
Same genus: Harpactes
The closest relatives of the Diard's Trogon that you can see in Khao Luang National Park (genus Harpactes, Asian Trogons) are Scarlet-rumped Trogon (about 30%) and Orange-breasted Trogon (about 20%), 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 Khao Luang National Park (26 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.
