The Central American agouti (Dasyprocta punctata) is a species of agouti from the family Dasyproctidae. [2] 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), [3] but a major review of the geographic variation is necessary. [2] The Central American agouti has also been introduced to Cuba and the Cayman Islands. [2] [4]

Contents

Though some populations are reduced due to hunting and deforestation, large populations remain [3] and it is not considered threatened. [1]

In an analysis of 240 species, agoutis came in fourth place for best sense of smell; better than dogs, which actually came out average. Their snouts are packed full of olfactory receptors. [5]

Appearance

Central American agoutis from the main part of their range weigh 3–4.2 kg (6.6–9.3 lb) and are typically reddish, orange or yellowish grizzled with black. [3] [6] In northern Colombia, western Venezuela, and on the Atlantic slope of Costa Rica and Panama the foreparts are brownish or blackish grizzled with tawny or olivaceous, the mid-body is orange, and the rump is black or cream. [3] [6] In western Colombia and Ecuador some have tawny foreparts and yellowish to the rump. [3] Agoutis from the disjunct southern population (Peru, Brazil, Bolivia, Paraguay and Argentina) which sometimes are treated as a separate species, Dasyprocta variegata, weigh 3–5.2 kg (6.6–11.5 lb) and are grizzled brown, yellowish and black, or grizzled black and orange. [3]

Behavior

Like other agoutis, Central American agoutis are diurnal and live in monogamous pairs. [6] They mainly feed on fruits and seeds, and are important seed dispersers. [1]
