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 agouti searching for food

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. [7]

Dasyproctidae is a family of large South American rodents, comprising the agoutis and acouchis. Their fur is a reddish or dark colour above, with a paler underside. They are herbivorous, often feeding on ripe fruit that falls from trees. They live in burrows, and, like squirrels, will bury some of their food for later use.

<span class="mw-page-title-main">Agouti</span> Genus of mammals

The agouti or common agouti is any of several rodent species of the genus Dasyprocta. They are native to Middle America, northern and central South America, and the southern Lesser Antilles. Some species have also been introduced elsewhere in the West Indies. They are related to guinea pigs and look quite similar, but they are larger and have longer legs. The species vary considerably in colour, being brown, reddish, dull orange, greyish, or blackish, but typically with lighter underparts. Their bodies are covered with coarse hair, which is raised when alarmed. They weigh 2.4–6 kg (5.3–13.2 lb) and are 40.5–76 cm (15.9–29.9 in) in length, with short, hairless tails.

The southern Amazon red squirrel, is a squirrel species from South America where it inhabits forests in much of north-western South America east of the Andes. Three subspecies are currently recognised. It is a dark red colour, or a dark brown grizzled with ochre, has whitish underparts and grows to a total length of 48 to 63 cm, including a very long tail.
