Preuss's red colobus

Preuss's red colobus, Piliocolobus preussi, is a red colobus endemic to the Cross-Sanaga Rivers ecoregion. The main population lives in Korup National Park in Southwest Province, Cameroon, where groups are often met near the main tourist camps. It is considered present in the adjacent Cross River National Park Oban Division in Nigeria, a few groups are reported from the Nkwende Hills and Nta Ali Forest Reserve, and another population lives in the Ebo forest of Littoral Province, Cameroon. It has a black head, a black back ticked with orange, and a bright red tail, limbs and cheeks, and like other colobus monkeys it is primarily a leaf eater. It was once treated as a subspecies of Pennant's and of the western red colobus. The IUCN lists it as critically endangered because of hunting pressure and habitat destruction, and many of the remaining groups live inside protected areas.
