The black howler (Alouatta caraya) or black-and-gold howler, is among the largest New World monkeys and a member of the Alouatta genus. The black howler is distributed in areas of South America such as Paraguay, southern Brazil, eastern Bolivia, northern Argentina, and Uruguay. This species is sexually dimorphic, with adult males having entirely black fur and adult females and babies of both sexes having an overall golden colouring; which emphasizes black-and-gold in the name. The IUCN Red List has classed the black howler as Near Threatened as a result of a recent population reduction due to a variety of human-caused factors.
The black howler is one of nine species of the Alouatta genus that have been identified and is in the Atelidae family. Because of this species' sexual dimorphism, the taxon for the black howler has been distinguished. Alouatta caraya

Possible
About 20% of wildlife watchers report a Black Howler sighting in Goiânia on a given day, based on 6 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and December
In those months about 40% of wildlife watchers report a Black Howler in Goiânia on a given day, against under 5% in January–February and May–November, the lowest months. Those are among Goiânia's wettest months, with about 170 mm of rain a month against almost none in July.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Black Howler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Goiânia, in our data
Goiânia is the only city on Wallace's Line with enough records to rate Black Howler sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Primates
The closest relatives of the Black Howler that you can see in Goiânia (order Primates) are Black-pencilled Marmoset (about 40%) and Black-striped Capuchin (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Howler is recorded against all the mammals logged in Goiânia (6 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.
