The Chacoan peccary weighs 30 - 40 kg (66 - 88 lb).
The Chacoan peccary is found in semi-arid thorn forest in areas of low rainfall and high temperature in the driest parts of the Gran Chaco. Its prime habitat is thorn forest characterized by emergent trees, a dense shrub layer and a ground cover of bromeliads and cacti. It is also found at lower density in open woodland.
Age to Maturity:
Females may produce their first litters when 2 years old.
The farrowing season is September - January.
Mean litter size is 2.7, with a range of 1 - 4. There is 1 year between births.
At least 9 years.
Cacti are its main food. It also eats the roots of bromeliads, fruit, and occasionally forbs.
The Chacoan peccary is diurnal.
It lives in small stable groups of 2-10 individuals, with most groups consisting of 4 - 5 adults and accompanying juveniles. These groups stay together even when they are being attacked and killed.
A study in the Paraguayan Chaco produced a density estimate of 0.43 individuals/sq km (1.1 individuals/sq mi) (Taber 1991).
The home range size of the Chacoan peccary is about 1100 hectares (2750 acres) and contains a core area of about 600 hectares (1500 acres) (Oliver 1993).
