Acouchy
Myoprocta 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
