The guira cuckoo, known in Spanish as the pirincho (Guira guira) is a species of gregarious bird found widely in open and semi-open habitats of northeastern, eastern and southern Brazil, Uruguay, Paraguay, Bolivia, and northeastern Argentina. It is the only species placed in the genus Guira.
The guira cuckoo was described and illustrated in 1648 by the German naturalist Georg Marcgrave in his Historia Naturalis Brasiliae. He used the name "Guira angatara". The word gûyrá means "bird" in the Old Tupi language. Later ornithologists based their descriptions on Marcgrave's account: Francis Willughby in 1678, John Ray in 1713, Mathurin Jacques Brisson in 1760, and Georges-Louis Leclerc, Comte de Buffon in 1779. When the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae in 1788 he included the guira cuckoo. He placed it with all the other cuckoos in the genus Cuculus and coined the binomial name Cuculus guira. The guira cuckoo is now the only species placed in the genus Guira that was introduced in 1830 by the French naturalist René Lesson. The species is monotypic: no subspecies are recognised. It is most closely related to the... Wikipedia →

Likely
About 60% of wildlife watchers report a Guira Cuckoo sighting in Iberá National Park on a given day, based on 1,077 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 284 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
May and September–October
In those months about 70% of wildlife watchers report a Guira Cuckoo in Iberá National Park on a given day, against about 30% in August, the lowest month.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Guira Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 13 parks where we can rate Guira Cuckoo sightings, Iberá National Park has the highest daily chance: about 60%. Next come Emas National Park (Brazil, about 40%) and El Palmar National Park (Argentina, about 30%). All parks ranked.
Same family: Cuculidae
The closest relatives of the Guira Cuckoo that you can see in Iberá National Park (family Cuculidae, Cuckoos) are Smooth-billed Ani (about 30%), Striped Cuckoo (about 30%) and Dark-billed Cuckoo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guira Cuckoo is recorded against all the birds logged in Iberá National Park (1,077 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.
