The Asian emerald cuckoo (Chrysococcyx maculatus) is a species of cuckoo in the family Cuculidae. It is found in Bangladesh, Bhutan, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Sri Lanka, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forest.
The Asian emerald cuckoo was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other cuckoos in the genus Cuculus and coined the binomial name Cuculus maculatus. Gmelin based his description on the "Spotted Curucui" from Ceylon that had been described and illustrated in 1776 by the English naturalist Peter Brown. The Asian emerald cuckoo is now placed together with 12 other species in the genus Chrysococcyx that was introduced in 1826 by the German zoologist Friedrich Boie. The genus name combines the Ancient Greek χρυσος khrusos meaning "gold" with κοκκυξ kokkux "cuckoo". The specific epithet maculatus is from Latin and means "spotted" or "blotched". The species is monotypic: no subspecies are recognised... Wikipedia →

Rare
Under 5% of wildlife watchers report an Asian Emerald Cuckoo sighting in Kaeng Krachan National Park on a given day, based on 151 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 201st most-seen of the 360 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.
December to February
In those months about 10% of wildlife watchers report an Asian Emerald Cuckoo in Kaeng Krachan National Park on a given day, against under 5% in March to November, the lowest months. Those are among Kaeng Krachan National Park's driest months, with about 35 mm of rain a month against 260 mm in September.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Asian Emerald Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 parks where we can rate Asian Emerald Cuckoo sightings, Kaeng Krachan National Park ranks 4th at under 5%. The best odds are in Doi Inthanon National Park (Thailand, about 10%), Manas National Park (India, about 10%) and Khao Yai National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Asian Emerald Cuckoo is recorded against all the birds logged in Kaeng Krachan National Park (151 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.
