![]() Poeppig (1832) later mentioned monkeys from Yurimaguas (Department of Loreto), which he believed to be the same species ( Fooden 1963). ![]() No type specimen was preserved, and Humboldt was under the misconception that they were a species of howling monkey ( Fooden 1963). Flat, trimmed skins collected in 1802, which were used as saddle blankets by Peruvian muleteers in the Province of Jaén, consistuted the basis of the description. The yellow-tailed woolly monkey was first described in 1812 by Alexander von Humboldt. flavicauda is threatened by an extremely high rate of clear-cutting of its cloud forest habitat and is listed as Critically Endangered on the 2006 IUCN Red List of Threatened Species ( IUCN 2006) and as Endangered on Appendix I of CITES ( 2005). Restricted to a narrow habitat belt in tropical montane cloud forests, it is the largest endemic primate found in Peru, as well as among the most endangered and least known ( Leo Luna 1987). 1975, 1977 Graves and O'Neill 1980 Leo Luna 1980 Leo Luna and Ortiz 1981 Parker and Barkley 1981). The yellow-tailed woolly monkey ( Oreonax flavicauda) inhabits the cloud forests of the northeastern slopes of the Andes Mountains, from 1,500 to 2,700 m a.s.l., in the Peruvian departments of San Martín and Amazonas, between 5☃0′8☃0′S and 77☃0′-78☀0′W ( Mittermeier et al. Urgently needed are a range-wide census of remaining habitat and populations, and educational initiatives and sustainable-use projects to ensure that the Alto Mayo Protected Forest is a truly protected area. This and its large body size, low density, low reproductive rate, its restriction to cloud forest and its limited geographic range, combined with a high rate of deforestation in the region, make the species especially susceptible to extinction. The difficulty we encountered in finding groups in the study area suggests that yellowtailed woolly monkeys have a large home range. flavicauda provided a group size of 17–20 individuals-higher than previous sightings by Mariela Leo Luna in the early 1980s, who observed an average group size of nine. Here I document the species' continued existence and status in the Bosque de Protección (Protected Forest) of Alto Mayo. ![]() From June to August 2004,I was involved in selecting a site for an extended study of its behavior and ecology. flavicauda continues to suffer rapid and widespread deforestation. No long-term research has been conducted on this species in more than 20 years. Populations of the yellow-tailed woolly monkey ( Oreonax flavicauda) persist in increasingly isolated, threatened cloud forests in scattered areas of the departments of San Martín and Amazonas, in northern Peru.
