Yellow-tailed woolly monkey
The yellow-tailed woolly monkey (Lagothrix flavicauda) is a species of New World monkey endemic to Peru. This rare primate is found only in the Peruvian Andes, primarily within the departments of Amazonas and San Martín, as well as in adjacent areas of La Libertad, Huánuco, and Loreto.
The yellow-tailed woolly monkey was originally classified in the genus Lagothrix along with other woolly monkeys. However, due to questionable primary sources, it was later placed in its own monotypic genus, Oreonax. Some researchers have proposed treating Oreonax as a subgenus of Lagothrix, while others have considered it a distinct genus.
A recent comprehensive study suggests that the yellow-tailed woolly monkey does indeed belong within the genus Lagothrix—a position now supported by the American Society of Mammalogists and the IUCN Red List.
The species was first described by Alexander von Humboldt in 1812 under the name Simia flavicauda, based on a skin obtained ten years earlier, which had been used by a local man as a horse saddle. Humboldt had never observed a live specimen or a preserved example and believed the animal belonged to the genus Alouatta. For over a century, the species was reported only on a few isolated occasions and was widely believed to be extinct.
In 1926, three specimens were collected in the Department of San Martín and brought to the Museum of Natural History. Initially believed to represent a new species, further examination confirmed that the specimens belonged to the yellow-tailed woolly monkey.
In 1974, a group of scientists led by Russell Mittermeier and funded by the World Wide Fund for Nature discovered a young yellow-tailed woolly monkey being kept as a pet in the city of Pedro Ruiz Gallo, Amazonas. The rediscovery drew national and international attention, prompting interest from conservation organizations seeking to assess the species' conservation status.
In the summer of 2004, scientists surveyed a remote area of San Martín, characterized by humid, mountainous tropical forest, in search of the yellow-tailed woolly monkey. The region, threatened by uncontrolled logging, was believed to host at least a small population. This area, along with two other locations in Peru, was included in the study.
Habitat loss due to deforestation poses a significant threat to the species. The introduction of agricultural plots in areas inhabited by the yellow-tailed woolly monkey has impacted its population. Local farmers have expressed concern about losing farmland to conservation efforts, although they stated that they do not hunt the monkeys. The land is primarily used for growing coffee and raising cattle. The challenge of balancing species conservation with the livelihoods of rural communities remains a central issue in the ongoing efforts to protect the yellow-tailed woolly monkey.
