The cougar preys on birds, camelids, deer, sloths, rodents, frogs, agoutis and lizards. Dasyproctidae is a family of large South American rodents, comprising the agoutis and acouchis. The edible immature seeds are often dispersed by rainforest rodents such as agoutis. The dense forest ecosystem is home to tapirs, agoutis, sloths, coati, monkeys and cats. Other important dispersing mammals were agoutis ("Dasyprocta azarae"), which sometimes cache seeds. They can be distinguished from other agoutis by their distinct coloring. This area features a giant anteater as well as red-rumped agoutis. Amongst the species present are howler monkeys, grey-winged trumpeters, toucans and red-rumped agoutis. Azara's agoutis will let out little barks when alarmed. Like other agoutis, Central American agoutis are diurnal and live in monogamous pairs. Competition from agoutis is avoided by a slight variation in activity cycles and food preferences. In Brazil all agoutis are often called "cutia" . The seeds are eaten by agoutis and by bruchid beetle larvae. For this reason the acouchis are also called tailed agoutis. Agoutis may grow to be up to in length and in weight.
