Appearance

The snout is grey while the skin on the rest of the face is pinkish or greyish, with a pale bluish border at the hairline, The eyelids and area under the eyes are particularly pale. Hairs on the crown and widow's peak have blackish bases and greyish-brown shafts. Hairs on the back, flanks and limbs have creamy grey bases and darker grey shafts, tipped with bands of yellowish-orange and black.

Range and habitat

This mangabey is endemic to East Africa, and only occurs in two forests in the Udzungwa Mountains of south-central Tanzania. Although it is known from areas with altitudes of from 300 to 1,800 m (1,000 to 5,900 ft), it is most common in mid-altitude evergreen forests, and mosaic woodland with mixed semi-deciduous and evergreen trees. It sometimes occurs in low altitude miombo woodland with Brachystegia species, and has been known to invade cropland.

Diet

The Sanje mangabey is a diurnal species and spends around half its time on the ground, and the rest foraging in the upper and middle canopy, and the understory. A loud "whoop-gabble" call is often emitted in the morning from these trees before the troop moves off to forage.

Fruit makes up about 70% of their diet.
