Records from Bolivia include ‘ceja de selva’ elfin forest and grasslands (3,600 m), cloud montane forest ‘Yungas’ forests, and sub Andean forests (1,400 m), although local reports may extend that from 4,000 to 1,000 m (Rumiz et al. 2007). Records from Peru include the same vegetation types as in Bolivia, but without records in grasslands or over 3,500 m (Barrio in prep.). Details on its ecology are unknown, although it seems to be solitary, active at day as well at night, and expected to be a browser frugivore in the forest understorey. Oxalis sp. has been identified among plant species eaten by Mazama chunyi. Nothing is known of reproduction or life in captivity
