The greater ani (Crotophaga major) is a bird in the cuckoo family. It is sometimes referred to as the black cuckoo. It is found through tropical South America south to northern Argentina. In 1760 the French zoologist Mathurin Jacques Brisson included a description and an illustration of the greater ani in his Ornithologie based on a specimen collected in Cayenne, French Guiana. He used the French name Le grand Bout-de-Petun and the Latin name Crotophagus Major. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. The greater ani was also described and illustrated in 1779 by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux.
When in 1788 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae, he included the greater ani. He placed it with the smooth-billed ani in the genus Crotophaga, coined the binomial name Crotophaga major and cited the earlier authors. Gmelin specified the type locality as Cayenne. The genus name combines the Ancient Greek krotōn meaning "tick" with... Wikipedia →

Rare
Under 5% of wildlife watchers report a Greater Ani sighting in Asuncion on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 153rd most-seen of the 224 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.
November and December
In those months about 10% of wildlife watchers report a Greater Ani in Asuncion on a given day, against under 5% in January to October, the lowest months. Those are among Asuncion's wettest months, with about 190 mm of rain a month against 40 mm in August.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Greater Ani 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 15
Of the 15 cities where we can rate Greater Ani sightings, Asuncion ranks 12th at under 5%. The best odds are in São Luís (Brazil, about 30%), Fortaleza (Brazil, about 30%) and Medellín (Colombia, about 10%).
GBIF citizen-science records
It is estimated from how often the Greater Ani is recorded against all the birds logged in Asuncion (26 verified sightings), 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.
