About the Common Marmoset
The common marmoset (Callithrix jacchus), also called white-tufted marmoset or white-tufted-ear marmoset, is a New World monkey. It originally lived on the northeastern coast of Brazil, in the states of Piauí, Paraíba, Ceará, Rio Grande do Norte, Pernambuco, Alagoas, and Bahia. Through release (both intentional and unintentional) of captive individuals, it has expanded its range since the 1920s to Southeast Brazil (its first sighting in the wild for Rio de Janeiro was in 1929), where it became an invasive species, raising concerns about genetic pollution of similar species, such as the buffy-tufted marmoset (Callithrix aurita), and predation upon bird nestlings and eggs.
The whole genome sequence of a female common marmoset was published on 20 July 2014. It became the first New World monkey to have its genome sequenced. Common marmosets are very small monkeys with relatively long tails. Males are slightly larger than females; males have an average height of 188 mm (7.40 in) and females have an average height of 185 mm (7.28 in). Males weigh 256 g (9.03 oz) on average and females weigh 236 g (8.32 oz) on average. The pelage of the marmoset is... Wikipedia →

Across all the parks we cover, that three-hour window holds the most Common Marmoset sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Where else can you see a Common Marmoset?
Only Tijuca National Park, in our data
Tijuca National Park is the only park on Wallace's Line with enough records to rate Common Marmoset sightings: about 30% of wildlife watchers there report one on a given day.
Where does the Common Marmoset sighting chance come from?
GBIF citizen-science records
It is estimated from how often the Common Marmoset is recorded against all the mammals logged in Tijuca National Park (137 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.
