The grey-capped cuckoo (Coccyzus lansbergi) is a species of bird in the tribe Phaenicophaeini, subfamily Cuculinae of the cuckoo family Cuculidae. It is found in Colombia, Ecuador, Peru, and Venezuela, as a vagrant on Bonaire and in the Galápagos Islands, and possibly in Panama.
The grey-capped cuckoo is more closely related to the Caribbean species of genus Coccyzus than it is to the others found in South America. The species is monotypic. The grey-capped cuckoo is 25 to 28 cm (9.8 to 11 in) long, about half of which is the tail. Males weigh 46 to 56 g (1.6 to 2.0 oz). The species' bill is stout, somewhat decurved, and black with sometimes a gray or yellow spot at the base of the mandible. Males and females have the same plumage. Adults have a slate-gray cap to below the eye. Their upperparts and wings are rufous brown. The upper surface of their tail is black; the underside of the central pair of feathers is black and the rest black with white tips. Their eye is surrounded by a narrow ring of bare skin that is yellow, white, or yellowish gray. Their underparts are dark rufous buff. Juveniles are similar to adults but have a brown crown...

With luck
About 10% of wildlife watchers report a Gray-capped Cuckoo sighting in Machalilla National Park on a given day, based on 36 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 121st most-seen of the 248 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Gray-capped Cuckoo is recorded against all the birds logged in Machalilla National Park (36 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.
