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 20% of wildlife watchers report a Squirrel Cuckoo sighting in Masaya Volcano National Park on a given day, based on 401 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 134 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April and October
In those months about 30% of wildlife watchers report a Squirrel Cuckoo in Masaya Volcano National Park on a given day, against about 10% in January and June–July, the lowest months.
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.
51st of 76
Of the 76 parks where we can rate Squirrel Cuckoo sightings, Masaya Volcano National Park ranks 51st at about 20%. 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.
Same family: Cuculidae
The closest relatives of the Squirrel Cuckoo that you can see in Masaya Volcano National Park (family Cuculidae, Cuckoos) are Groove-billed Ani (about 30%) and Lesser Ground-Cuckoo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Squirrel Cuckoo is recorded against all the birds logged in Masaya Volcano National Park (401 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.
