The amount and pattern of the white markings can be quite variable. There are few measurements available for this bear. No populations have been documented from areas that lack bromeliads and fruits. Mating occurs in April, May, and June, and pairs stay together for a week or two, with copulation occurring numerous times. Litters of one, two, or occasio nally three cubs are born from November to February.
Nothing is known of the social organization of spectacled bears in the wild.
In captivity, females and their cubs regularly vocalize to communicate, using two and five types of calls respectively. DIET Spectacled bears eat a wide variety of foods, including rabbits, mice, birds, berries, grasses, and orchid bulbs, but have a strong preference for the leaves, bases, and hearts of plants of the Bromeliaceae family and the fruits of other plant groups. They will sometimes climb cacti to feed on fruit at the top. Tree nests are often constructed as a platform to feed from fruit-laden branches and to sleep in.
