The buffy-headed marmoset is an
arboreal
,
diurnal
monkey weighing 0.4 kg (14 oz). It lives in
Brazil
's Atlantic coastal forest. It is unusual in that its diet includes significant amounts of plant gums as well as fruit.
These marmosets are
monogamous
. A dominant mated pair in a troop maintains its status through aggressive interaction. A litter includes from 1 - 4 young.
The buffy-headed marmoset occurs along the southeast coast of
Brazil
in the states of Espirito Santo and Minas Gerais. It is affected by the continuing degradation of the Atlantic coastal forest. Marmosets have been used for biomedical research and captured for the pet trade.
Tidbits
*** The buffy-headed marmoset is specialized for eating plant gums instead of fruit as a source of carbohydrates during periods of fruit scarcity. It can colonize habitats where edible fruit may be scarce during most of the year.
(

.
*** Field studies have shown that buffy-headed marmosets are highly adaptable and can thrive under relatively harsh conditions in marginal and secondary forest patches

History of Distribution:
The buffy-headed marmoset occurs along the southeast coast of
Brazil
. In 1977 it was thought only to occur in the state of Espirito Santo between the Rio Doce and the Rio de Janeiro-Espirito Santo border. In 1980 it was also observed in the neighboring state of Minas Gerais. Its populations are restricted to small, isolated remnants of the original Atlantic coastal forest, most of which are privately owned.
