The common squirrel cuckoo (Piaya cayana) is a large and active species of cuckoo found in wooded habitats from northwestern Mexico to northern Argentina and Uruguay, and on Trinidad. The species was formerly considered to be conspecific with the Mexican squirrel cuckoo (Piaya mexicana).
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the common squirrel cuckoo in the fourth volume of his Ornithologie based on a specimen collected in Cayenne, French Guiana. He used the French name Le coucou de Cayenne and the Latin name Cuculus cayanensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson in his Ornithologie. One of these was the common squirrel cuckoo. Linnaeus included a terse description, coined the binomial name Cuculus cayanus and cited Brisson's work. The common squirrel cuckoo is now placed with the Mexican squirrel cuckoo and the black-bellied cuckoo... Wikipedia →

Possible
About 30% of wildlife watchers report a Squirrel Cuckoo sighting in Parque Natural Metropolitano on a given day, based on 1,319 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 328 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Squirrel Cuckoo in Parque Natural Metropolitano on a given day, against about 20% in June to September, the lowest months. That is one of Parque Natural Metropolitano's driest months, with about 15 mm of rain against 350 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Squirrel Cuckoo sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
21st of 76
Of the 76 parks where we can rate Squirrel Cuckoo sightings, Parque Natural Metropolitano ranks 21st at about 30%. The best odds are in Santa Rosa National Park (Costa Rica, about 50%), Serra dos Órgãos National Park (Brazil, about 50%) and Ostional Wildlife Refuge (Costa Rica, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Squirrel Cuckoo is recorded against all the birds logged in Parque Natural Metropolitano (1,319 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.
