Descriptive notes. Head-body 36-39 cm, tail 20-24 cm; weight 1.1-5 kg. Roughly half the size of Nasua , the Mountain Coati has a gray-brown back and 6-8 bands on the tail. Its snout is more elongated and comes to a sharper point than in other coati species, and the tip of its nose is naked.

Habitat. Montane forests above 2000 m.

Food and Feeding. Primarily insectivorous, all 54 scat samples analyzed in Colombia contained insects, especially Coleoptera (41%), Orthoptera, Myriapoda, and Hymenoptera. Vertebrates and fruits were also eaten, each representing about 7% of the diet. Although all coati species find food on the forest floor, Mountain Coatis appear to be unique in leaving behind many small holes as they forage, with as many as 5000 being observed in one heavily foraged 35 m ® area. This may be related to their more elongated, sharper snouts.

Activity patterns. From anecdotal reports, Mountain Coatis appear to be primarily diurnal and terrestrial, but this has not been studied in detail.

Movements, Home range and Social organization. Because Mountain Coatis are sometimes seen in groups, and sometimes alone, they are presumed to have a social organization similar to other coatis, but there have been no studies on their behavior or movement patterns.

Breeding. A litter size of four is reported but their breeding biology has not been studied.

Status and Conservation. With only one published study from the field we know very little about Mountain Coatis and The IUCN Red List has classified them as Data Deficient. One report from Venezuela suggests that they may be vulnerable to habitat fragmentation.
