Adults are sexually monomorphic. Their head, neck, upper breast, primaries, and tail are a glossy violet-black color, with a bare patch of red and violet-colored skin around the eyes.

With luck
About 10% of wildlife watchers report a Coral-billed Ground-Cuckoo sighting in Khao Yai National Park on a given day, based on 194 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 132nd most-seen of the 278 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
March

GBIF citizen-science records
It is estimated from how often the Coral-billed Ground-Cuckoo is recorded against all the birds logged in Khao Yai National Park (194 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.
