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 40% of wildlife watchers report a Guira Cuckoo sighting in Emas National Park on a given day, based on 77 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 52nd most-seen of the 187 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 60% of wildlife watchers report a Guira Cuckoo in Emas National Park on a given day, against about 20% in August and November, the lowest months. That is one of Emas National Park's driest months, with about 35 mm of rain against 190 mm in January. April and December–February have too few records to rate.
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.
2nd of 13
Of the 13 parks where we can rate Guira Cuckoo sightings, Emas National Park ranks 2nd at about 40%. The best odds are in Iberá National Park (Argentina, about 60%). All parks ranked.
Same family: Cuculidae
The closest relatives of the Guira Cuckoo that you can see in Emas National Park (family Cuculidae, Cuckoos) are Smooth-billed Ani (about 30%) and Squirrel Cuckoo (about 20%), 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 Emas National Park (77 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.
