Barry R. Koffler Collared peccaries are adaptable to a wide variety of habitats, from deserts to tropical rain forests. Collared peccaries are found from Arizona to northern Argentina, and only the white-tailed deer has a larger range. The average collared peccary weighs about 36 pounds. Its coat is black, with a white collar running from the shoulder down to the front of the chest. It also has a very dark mane composed of long hairs which can be made to stand upright.
Peccaries are herd animals their entire lives.
On BCI they usually travel in groups of two to ten. When moving from place to place they go single file, but fan out when they get to feeding areas. Peccaries tend to feed early and seek shelter during the heat of the day, sometimes under logs or in burrows created by other animals. On BCI they often sleep lying on the forest soil in a sheltered location, or an entire group may squeeze into a large hollow in a big tree. Each group is made up of individuals who use scents from skin glands to mark each other for easy recognition.
