The Bald uakari or bald-headed uakari (Cacajao calvus), is a species of New World monkey characterized by a very short tail; bright, crimson face; a bald head; and long coat. The bald uakari is restricted to várzea forests and other wooded habitats near water in the western Amazon of Brazil and Peru.

Taxonomy

There are four recognized subspecies of the bald uakari, each of which is considered vulnerable to extinction:

White Bald-headed Uakari (Cacajao calvus calvus)
Ucayali Bald-headed Uakari (Cacajao calvus ucayalii)
Red Bald-headed Uakari (Cacajao calvus rubicundus)
Novae's Bald-headed Uakari (Cacajao calvus novaesi)

Physical Description

The bald uakari weighs between 2.75 and 3.45 kg (6.1 and 7.6 lb), with head and body lengths average 45.6 cm (18.0 in) (male) and 44.0 cm (17.3 in) (female). In general, the bald uakari has a long, shaggy coat ranging from white in color to red and its head is bald. The tail is bob-like and rather short for a New World monkey (about 5.9 inches (15 cm), at only half the length of the body and head combined. Its scarlet red face is due to the lack of skin pigments and plentiful capillaries that run under its facial tissue.
