Large rodents: Rodents are chisel-toothed mammals which are important fruit and seed consumers and dispersal agents. Rodents come in a wide range of sizes. In this section we include the large rodents which weigh more than about 2 kilograms.
Paca
Agouti paca Paca image
Makushi name: Urana
Creole name: Labba
Size: body=70 cm; weight=8 kg
Description: Large bodied and stocky; reddish-brown with four obvious lines or stripes of white spots from shoulder to rump on each side, and a very short, inconspicuous tail. This is the second-largest rodent in Iwokrama. Bright red eyeshine.
Activity: Terrestrial, nocturnal, it is often active late in the evening (midnight or later), especially in areas where it is frequently hunted (it is prized for its tasty flesh).
Habits: Solitary or sometimes in male-female pairs. Usually silent. Often seen as it forages for fruit on the forest floor and especially along creeks, streams, and rivers.
Habitat: Forest, secondary brush.
Signs: Relatively broad tracks (40 mm wide or more in adults) with four toes showing on the front track and three on the hind.
Status: Often common.

Acouchy

Makushi name: Kusiwai
Creole name: Acouchy
Size: body= 35 cm; tail= 6 cm; weight= 1.5 kg
Description: Small-sized, ungulate-like rodent, similar to but smaller than an agouti. Upperparts dark reddish-brown grading to reddish-orange on sides and legs, black on mid-back and rump; rump with long erectile hairs; belly orange. Relatively long ears compared to an agouti. Short, thin tail white on underside and at tip (noticeable and much longer than an agouti). Long, thin legs and long hindfeet.
Activity: Diurnal (most active in early morning or late afternoon), terrestrial.
Habits: Solitary. Feeds on seeds and fruit, and often buries individual seeds and nuts for later use. Dens in hollow logs. When alarmed, it bounds away quickly and then freezes, eventually circling back to the spot from which it was flushed. Calls include chirps, whistles, and squawks, and it often drums the feet in alarm.
Habitat: Primary forest. Occurs throughout the forest though most commonly seen near dense brush or forest edge. Sometimes seen in gallery forest or forest bordering savannah.
Signs: Tracks similar to, but less than half the size of, an agouti.
Status: Not recorded from Iwokrama, but is known from southwestern Guyana and probably will be found in the reserve.
Red-rumped Agouti

Makushi name: Akuri, Maikupiyu, EwaropaimÓ, Iwoto, KanskiÓmÓ, KusiwÓ
Creole name: Accurrie, Akuri
Size: body=50 cm; weight=3.5 kg
Description: Medium-sized, long-legged rodent with large, rectangular head--rather like a short-eared rabbit on stilts. Head, back, and shoulders grey-black, with crest of black hairs on neck and shoulders; contrasting rump bright orangish-red and covered with long erectile hairs; belly grizzled grey; tiny, inconspicuous tail.
Activity: Diurnal (most active in early morning or late afternoon), terrestrial.
Habits: Solitary, or in male-female pairs. Feeds on nuts, seeds and fruit, and sometimes buries its food in shallow pits for later use. Easiest to observe at dawn or dusk near fruiting trees or traveling along habitually used paths. Calls include barks, grunts, and squeals, and may drum its hindfeet on the ground in alarm.
Habitat: Primary or secondary forest. Occurs throughout the forest, although most common in areas of dense brush or undergrowth, and near streams or swamps.
Signs: Distinctive tracks 25 mm (forefoot) to 30 mm (hindfoot) in width. Print of hindfoot with three elongated toes and pointed claws, forefoot showing three or four toes, depending on depth of the print.
Status: Locally common in Iwokrama.
