The neotropic cormorant or olivaceous cormorant (Nannopterum brasilianum) is a medium-sized cormorant found throughout the American tropics and subtropics, from the middle Rio Grande and the Gulf and Californian coasts of the United States south through Mexico and Central America to southern South America, where it is called by the indigenous name of biguá. It also breeds in the Bahamas, Cuba, and Trinidad. It can be found both on coasts (including some mangrove areas) and in inland waters. In Peru, the neotropic cormorant is used by the Uru people for fishing.
The neotropic cormorant was documented in 1658 by the Dutch naturalist Willem Piso after travels in Brazil. This formed the basis for the formal description and naming of the species by Johann Friedrich Gmelin in 1789. He placed it with the petrels in the genus Procellaria and coined the binomial name Procellaria brasiliana. Many authors preferred to use Alexander von Humboldt's 1805 description of Pelecanus olivaceus because the identity of Piso's birds was considered uncertain. Later, ornithological... Wikipedia →

No species of the same family or order lives in Mendoza, so these are its closest relatives here: other birds.
Possible
About 20% of wildlife watchers report a Bigua cormorant sighting in Mendoza on a given day, based on 72 verified sightings from GBIF citizen-science data. It is the 32nd most-seen of the 69 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.
March and December–January
In those months about 30% of wildlife watchers report a Bigua cormorant in Mendoza on a given day, against under 5% in August and September, the lowest months. Those are among Mendoza's wettest months, with about 40 mm of rain a month against 10 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Bigua cormorant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
27th of 64
Of the 64 cities where we can rate Bigua cormorant sightings, Mendoza ranks 27th at about 20%. The best odds are in Barranquilla (Colombia, about 50%), León (México, about 50%) and São Luís (Brazil, about 50%).
GBIF citizen-science records
It is estimated from how often the Bigua cormorant is recorded against all the birds logged in Mendoza (72 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.
