Bears have a wide distribution in the Northern Hemisphere. Here, the most widely distributed species include the polar bears, which inhabit the circumpolar ice pack; the brown bears, which live throughout northern North American and north to north-central Eurasia; and the American black bear, which stretches from northern Mexico well into Canada. Both the sun bear and sloth bear reside in Southeast Asia. The range of the Asiatic black bear is somewhat larger, extending from Afghanistan to southeastern Russia. The giant panda has the smallest range of all bears, with six small populations known from the Tibetan plateau in southwestern China. The spectacled bear, the only ursid that inhabits in the Southern Hemisphere, lives around the Andes in South America, including sites in Bolivia, Colombia, Ecuador, Peru, and Venezuela.
