It is distinguished from U. t. thibetanus by its longer, thicker fur and smaller, whiter chest mark.[2] During the summer, Himalayan black bears can be found in warmer areas in Nepal, China, Bhutan, India and Tibet at altitudes of {{convert|10,000|to|12,000|ft|m}} up near the timberline. For winter, they descend as low as 5,000 feet, to more tropical forests. On average, they measure from {{convert|56|to|65|in|cm}} nose to tail and weigh from {{convert|200|to|265|lb|kg}}, though they may weigh as much as 400 pounds in the fall, when they are fattening up for hibernation.[3] DietThey are omnivorous creatures and will eat just about anything. Their diet consists of acorns, nuts, fruit, honey, roots, and various insects such as termites and beetle larvae. If food is scarce, they may turn to eating livestock such as sheep, goats, and cattle.[3] BreedingThey reach sexual maturity at approximately three years. Mating occurs in October with usually two cubs born in February while the mother is still hibernating. The offspring usually stay with their mother into the second year.[3] StatusThis subspecies is listed as 'vulnerable' due to encroachment of human population, forest fires and the timber industries; these have all reduced the bear's habitat. There is also a high mortality rate among the newborn. And even though hunting of the Himalayan black bear has been forbidden since 1977, there is still a large problem with poaching.[3] References1. ^{{cite journal|last1=Pocock|first1=R.
