28-3-2017 CARARA NAT PARK, COSTA RICA - CENTRAL AMERICAN AGOUTI (Dasyprocta punctata)

The Central American agouti (Dasyprocta punctata ) is a species of agouti from the family Dasyproctidae. The main portion of its range is from Chiapas and the Yucatan Peninsula (southern Mexico), through Central America, to northwestern Ecuador, Colombia and far western Venezuela. A highly disjunct population is found in southeastern Peru, far southwestern Brazil, Bolivia, western Paraguay and far northwestern Argentina. The disjunct population has been treated as a separate species, the brown agouti (Dasyprocta variegata ), but a major review of the geographic variation is necessary. The Central American agouti has also been introduced to Cuba and the Cayman Islands.

Though some populations are reduced due to hunting and deforestation, large populations remain and it is not considered threatened.

The Central American agouti is a large South American rodent. It is typically reddish, orange, or yellowish grizzled with black. Populations that live in northern Colombia, western Venezuela, and on the Atlantic slope of Costa Rica and Panama have brownish or blackish grizzled with tawny or olivaceous foreparts; their mid-body is orange, and the rump is black or cream. In western Colombia and Ecuador, some have tawny foreparts and yellowish to the rump. Agoutis from the disjunct southern population (Peru, Brazil, Bolivia, Paraguay, and Argentina) are grizzled brown, yellowish, and black, or grizzled black and orange.

Central American agoutis occur from Chiapas and the Yucatan Peninsula (southern Mexico), through Central America, to northwestern Ecuador, Colombia, and far western Venezuela. A highly disjunct population is found in southeastern Peru, far southwestern Brazil, Bolivia, western Paraguay, and far northwestern Argentina. Central American agoutis live in tropical moist forests and cultivated areas such as plantations and rural gardens.

In the wild, Central American agoutis are shy animals. They live in pairs and are active during the day. Each pair occupies territory with fruiting trees usually near water. Males defend their territory and drive off intruders through fighting, aggressive displays, or vocally emitting dog-like barks. Agoutis conceal themselves at night in hollow tree trunks or in burrows among roots. Active and graceful in their movements, their pace is either a kind of trot or a series of springs following one another so rapidly as to look like a gallop. They also take readily to water, in which they swim well. When feeding, agoutis sit on their hind legs and hold food between their fore paws. They frequently hoard fruits and seeds in small, buried stores for later consumption or when food is scarce. If threatened, they typically stay motionless although they are very fast animals and can move with remarkable speed and agility.
