The violet cuckoo (Chrysococcyx xanthorhynchus) is a species of cuckoo in the family Cuculidae. The males have glossy violet feathers on the head and upper parts of the body. The blackish tail has a white tip, and barred outer feathers. The most spectacular feature is the brightly iridescent violet chin and upper breast. The belly is white with broad black, green or violet bars. Mature males also have a red eye-ring. The closely related species, C. amethystinus has a glossy blue-violet throat patch rather than reddish violet of this cuckoo.
The females have mottled, greenish-bronze upper parts and a dark brown crown. There are white markings around the eyes and sometimes on the forehead. The central tail feathers are greenish while the outer feathers are rufous with greenish bars. The outer rectrices are barred black and white. The breast is whitish with bronze-green bars and variably washed rufous markings.
Juveniles have barred rufous and greenish bronze feathers on the upper parts of the body, a bright rufous crown, rufous and mottled green or brown wings, a barred brown and rufous tail and brown-barred white under parts.

Rare
Under 5% of wildlife watchers report a Violet Cuckoo sighting in Gunung Leuser National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 136th most-seen of the 166 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and December
In those months about 10% of wildlife watchers report a Violet Cuckoo in Gunung Leuser National Park on a given day, against under 5% in January–March and May–November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Violet Cuckoo is recorded against all the birds logged in Gunung Leuser National Park (6 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.
