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 →

Rare
Under 5% of wildlife watchers report a Guira Cuckoo sighting in Tijuca National Park on a given day, based on 49 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 142nd most-seen of the 214 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Guira Cuckoo in Tijuca National Park on a given day, so our monthly data shows no clear season.
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.
12th of 13
Of the 13 parks where we can rate Guira Cuckoo sightings, Tijuca National Park ranks 12th at under 5%. The best odds are in Iberá National Park (Argentina, about 60%), Emas National Park (Brazil, about 40%) and El Palmar National Park (Argentina, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Guira Cuckoo is recorded against all the birds logged in Tijuca National Park (49 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.
