New Locality for the Yellow-tailed Woolly Monkey

Abstract

The authors found a small number of yellow-tailed woolly monkeys in a part of Peru 200 kilometres from where in 1974 the species was ‘rediscovered’ (having been believed extinct). As the area is also the home of a number of endemic Peruvian birds, they suggest it may have been a refugium in the late Pleistocene and should be both protected and explored for other possible undescribed species.
