Buffyheaded marmoset

Callithrix flaviceps

TAXONOMY

Hapale flaviceps Thomas, 1903, Espirito Santo, Brazil. OTHER COMMON NAMES

French: Ouistiti à tête jaune; German: Gelbkopfbuschelaffe; Portuguese: Sagui-da-serra.

PHYSICAL CHARACTERISTICS

Average weight: 14.3 oz (406 g); head and body length: 8.7-9.8 in (22.2-24.8 cm); tail length: 11.7-13.8 in (29.8-35 cm); Fur appears on the head and ear tufts are buffy-yellowish in color.

DISTRIBUTION

Forest remnants in the states of Espirito Santo and Minas Gerais.

HABITAT

Seasonal, altitudinal Atlantic coastal forest. BEHAVIOR

Group size varies between 5-15; a single group that was monitored over six years living together included 11-15 individuals; 3-6 adult males, and 1-6 adult females. Home-range size is around 88 acres (35.5 ha), and daily path length is about 0.75 mi (1.2 km).

FEEDING ECOLOGY AND DIET

Buffy-headed marmosets feed primarily on exudates and insects; exudates are procured through gouging on tree bark. However, they often eat more fruit when it becomes more abundant in their highly seasonal habitat.

REPRODUCTIVE BIOLOGY

Despite the large number of adult females that may live in a group, only one of them breeds. A daughter may inherit the position of the breeding female, while the mother still remains in the group and contributes to infant care, along with other adult and subadult group members. Mating is monogamous, but mating with more than one male (polyandry) is suspected. Two births per year is normal, and probably seasonal.

CONSERVATION STATUS

Endangered. Habitat fragmentation and loss are the major threat.

SIGNIFICANCE TO HUMANS

Often captured for the pet trade; this species is also a draw for ecotourists. ♦
