Buffy-tufted marmoset

The buffy-tufted marmoset (Callithrix aurita), also called the buffy tufted-ear or white-eared marmoset, is a New World monkey of the Atlantic coast forests of southeast Brazil and the southernmost of all marmosets. It resembles the common marmoset but is somewhat larger, probably the largest Callithrix, at 400 to 450 grams and 19 to 25 centimetres, with a whitish face, brown crown and short white ear tufts. It lives in groups of four to eight with one breeding pair, feeds on resins, gum, fruit and small animals, and is threatened by habitat destruction and hybridization with introduced marmosets. It is endemic to the Atlantic Forest in Minas Gerais, Sao Paulo and Rio de Janeiro.
