Likely
About 50% of wildlife watchers report an Ashy Drongo sighting in Khao Yai National Park on a given day, based on 1,595 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
December
In that month about 80% of wildlife watchers report an Ashy Drongo in Khao Yai National Park on a given day, against under 5% in June, the lowest month. That is one of Khao Yai National Park's driest months, with about 15 mm of rain against 330 mm in September.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Ashy Drongo sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
4th of 33
Of the 33 parks where we can rate Ashy Drongo sightings, Khao Yai National Park ranks 4th at about 50%. The best odds are in Cat Tien National Park (Vietnam, about 70%), Kinabalu Park (Malaysia, about 50%) and Kaeng Krachan National Park (Thailand, about 50%). All parks ranked.
Same genus: Dicrurus
The closest relatives of the Ashy Drongo that you can see in Khao Yai National Park (genus Dicrurus, Drongos) are Hair-crested Drongo (about 50%), Greater Racket-tailed Drongo (about 40%) and Bronzed Drongo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ashy Drongo is recorded against all the birds logged in Khao Yai National Park (1,595 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.
