Red-rumped agouti

Overview

The red-rumped agouti is a long-legged rodent with a small tail and rounded ears. Its coarse coat is brownish, with an orange-red rump. Oakland Zoo emphasizes the longer hind limbs and the animal’s ability to leap. These proportions distinguish it from a squat guinea pig despite their broadly similar appearance.

Its ecological influence extends beyond eating fallen fruit. The Smithsonian account describes agoutis opening Brazil nuts and burying surplus seeds for later use. Forgotten stores help disperse the trees. Seeds, fruits, roots and leaves dominate the listed diet, with insect larvae also eaten when plant food is scarce. Agoutis sit on their hind legs and hold food in their forelimbs.

The Smithsonian describes small family groups and young that can see at birth and move quickly soon afterwards. Its account gives gestation as up to 120 days and litters of one to four. Those are the Smithsonian’s reported values; Oakland’s summary gives a narrower typical offspring range. Neither institutional account should be read as a census of wild family size.
