The spectacled bear gets its name from the distinctive circular bands which ring its eyes. The markings vary slightly from bear to bear, but the general look is the same. The markings are a creamy-yellowish color while the rest of the fur on the animal could be anywhere from brown to black. The spectacled bear is a small animal as bears go, the males generally weighing from 220 to 340 pounds, and the females 140 to 180 pounds. The animals are generally from 60-72 inches in length, with the females being about 30% smaller, on average, than the males.
The females are generally mature somewhere between their 4th and 7th years. After maturity, the animals will mate between May and June, with the litters of up to 3 being born during the Nov-Feb period. The cubs weigh a mere 10-11 1/2 ounces at birth. During the mating months, the bears will pair up and stay together for up to two weeks, copulating frequently. Like most other bears, the female requires this stimulation to ovulate.
Apart from basic mating and other minor habits, we have no information on the social life of these animals in the wild. The bears that have been studied in captivity have shed some light on their society. Females and cubs communicate with vocalizations, of which somewhere between two and five calls have been identified (depending on which source you check with).
The spectacled bear is a very adaptable animal. It, like the brown bear, is found in widely varying habitats. This bear is found in steppe lands, rainforests, cloud forests, and even coastal scrub desert land. The destruction of its habitat by mankind poses perhaps the greatest threat, since the range of the animal has declined greatly as development of its former habitats has increased.
This bear is found throughout the forested mountain areas of South America. All the way from Venezuela and Columbia, through to Ecuador, Peru, and on into Bolivia. Generally, these animals remain at altitudes of 6,000 - 8,000 feet, but they have been found from 600-13,800 feet as well.
The spectacled bears eat a wide variety of food, ranging from mice, rabbits, birds, berries, grasses and orchid bulbs all the way to their favorite food, the leaves, bases, and hearts of the Bromeliacae plant family. Many times, these animals will climb cacti to taste of the fruit at the top. Similarly, they will build nests in the tops of trees to use as a crude form of feeding platform as well as a sleeping place and day bed.
 Although black is the most common color of this bear, its color can range from light brown to dark brown. There is even a population of white Ursus americanus living on a remote island off the west coast of Canada.
A solitary, predominantly vegetarian creature, the black bear uses its keen sense of smell to search out fruit, nuts, berries, and roots.

 Order: Carnivora, Family: Ursidae The American black bear is one of the most common bear species; it is also one of the world's largest terrestrial carnivores.
When standing upright, black bears measure approximately 5 to 6 feet tall, with a tail length of roughly 5 inches.
Depending on the food supply available in their range, female black bears weigh from 100 to 600 pounds, and males average between 250 and 700 pounds.

 Order: Carnivora, Family: Ursidae The polar bear has a thick, well-insulated coat comprising water-repellent guard hairs and a dense undercoat.
The polar bear's coat and a layer of fat beneath it help keep the bear warm in its arctic habitat.
The polar bear's fur is not soft, but quite oily, which helps repel water. It measures about 1 1/2 inches thick, and can vary in color from white to creamy-yellow to light brow...

 Order: Carnivora, Family: Ursida Technically, brown and grizzly bears are classified as the same species. Brown bear refers to the members of the species found in coastal areas; brown bears found inland and in northern habitats are called grizzlies.
The brown bear can weigh between 200 and 1,700 pounds.
Brown bears are the largest of all carnivores. They measure 5 to 9 feet in length from head to rump, and their tails are 2...
