South American Coati

Identification

The South American coati, also known as the ring-tailed coati or brown-nosed coati, is a member of the raccoon family and a distinctive tropical mammal. Adults typically weigh 2–7.2 kg (4.4–15.9 lb) and measure 85–113 cm (33–44 in) in total length, with the tail accounting for approximately half of this measurement. The species exhibits highly variable coloration, and while its tail bears rings that may be only somewhat visible, its most distinguishing feature is the absence of the largely white snout found in its northern relative, the white-nosed coati. The brown nose is therefore the field mark that separates this species from congeners.

Range & Habitat

The South American coati is widespread across tropical and subtropical South America, occurring in lowland forests east of the Andes from Colombia and the Guianas south to Uruguay and northern Argentina, reaching altitudes up to 2,500 m (8,200 ft). Occupancy is significantly positively related to forest cover and negatively related to elevation. The species has been recorded in western Ecuador and northern and western Colombia, and in Argentina from Santa Fe and Salta Provinces. It has also been introduced to the island of Mallorca, where it is considered invasive. The smaller mountain coati occupies higher elevations, though there is considerable range overlap.

Behaviour & Diet

The South American coati is diurnal and equally at home on the ground and in trees. It is omnivorous, feeding primarily on fruit, invertebrates, small animals, and bird eggs. The species forages in the high canopy for fruit and uses its distinctive snout to probe crevices for prey. It also searches for food by turning over rocks and ripping open logs with its claws. Females typically live in large social groups called bands of 15–30 individuals, while males are usually solitary—a behavioral difference that once led scientists to classify solitary males as a separate species called coatimundis. Group members produce soft whining sounds and distinctive alarm calls consisting of loud woofs and clicks. When alarmed, coatis climb trees before dropping to the ground and dispersing. The species typically sleeps in trees.

Best Time & Places to See It

South American coatis are most active during daylight hours and can be encountered in forested habitats throughout their range in Colombia, the Guianas, Ecuador, Peru, Bolivia, Brazil, Paraguay, Uruguay, and Argentina. They are particularly visible during fruiting seasons when they forage in the canopy and on the forest floor. Female bands are more easily observed than solitary males. Predators include foxes, jaguars, jaguarundis, and occasionally humans.

Photography Tips

The coati's habit of foraging on the ground and in trees provides excellent photographic opportunities in good daylight. Look for bands of females moving through the understory and along forest trails, particularly near fruiting trees. The distinctive ringed tail and brown nose are key identification features to capture in images. Early morning or late afternoon light is ideal for photographing these diurnal animals in their natural forest habitat.
