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...

Rare
Under 5% of wildlife watchers report a Gray-capped Cuckoo sighting in Guayaquil on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 137th most-seen of the 167 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a Gray-capped Cuckoo in Guayaquil on a given day, against under 5% in March to January, the lowest months. That is one of Guayaquil's wettest months, with about 220 mm of rain against almost none in September.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Gray-capped Cuckoo sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Guayaquil, in our data
Guayaquil is the only city on Wallace's Line with enough records to rate Gray-capped Cuckoo sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gray-capped Cuckoo is recorded against all the birds logged in Guayaquil (8 verified sightings), 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.
