Gray woolly monkey

The gray woolly monkey (Lagothrix lagotricha cana), also known as Geoffroy's woolly monkey, is a woolly monkey of Bolivia, Brazil and Peru, named for its thick gray coat and dark hands, feet, face and inner arms. It was once ranked as a full species and is now treated by the American Society of Mammalogists and the IUCN as a subspecies of the common woolly monkey. It lives mainly in cloud forest between about 1,000 and 2,500 metres, though Bolivian animals have been reported as low as 700 metres. It feeds mostly on fruit, taking young leaves and sometimes seeds when fruit is scarce, and it travels high in the canopy using its prehensile tail. Groups of 11 to 25 mixed-age animals share feeding sites with neighbours with little aggression. Males average about 9.5 kilograms and females about 7.7 kilograms. The IUCN has listed it as Endangered since 2008 after a population drop of about half in 45 years, driven by hunting for food and pets and by deforestation and tin mining. It is protected in many national parks and listed in CITES Appendix II.
