The Kodiak Bear, Ursus arctos middendorffi, also known as the Alaskan brown bear is the largest subspecies of brown bear, Ursus arctos, and lives solely on the Kodiak Archipelago, a group of islands south of Alaska. Scientist C.H. Merriam named the species in honor of the celebrated Russian naturalist Dr. A. Th. von Middendorff. There are approximately 3000 Kodiak bears, and they have been isolated from other bears for over 10,000 years. Although the current population is healthy and productive, it may be more susceptible to new diseases or parasites than more diverse brown bear populations.

Kodiak bears are among the largest in the world, almost equalling polar bears in size, and can grow to be more than 10 feet long and weigh more than 1000 pounds, with females being about two-thirds the size of the males. They are similar to grizzly bears in color, ranging from blond to dark brown, and, like grizzly bears, they have a mass of muscle on their shoulders, a hump, which makes them powerful diggers and hunters. They tend to be solitary, except for mothers with cubs, but will congregate peacefully at prime fishing spots to gorge on salmon, returning to the same spot year after year, building up a store of fat to get them through the winter. Also, when food is concentrated in small areas, such as grass flats, berry patches, a dead whale, or even an open garbage dump they often arrive in large numbers. In addition to fish, they eat grass, plants and berries. Unlike most bears, Kodiak bears are diurnal, active during the day, and have one of the keenest sense of smell in nature.

Kodiak bears mate from early May to July, and are monogamous, staying together from two days to two weeks. Gestation is only around 70 days, but the female suspends gestation until she has put on enough body fat to den for the winter, usually late October. The females give birth in the den in January or February, with a litter size of two to three cubs. The cubs weigh about one pound at birth, and the mother will stay in the den to nurse them until they are around 20 pounds and the family emerges from the den in June. The cubs remain with the mother for at least two years, often three. Sows are sometimes seen with five to six cubs where they have adopted cubs from other litters, possibly on the death of another female. The bears are sexually mature at five years, and continue to produce cubs for the rest of their lives. Their average lifespan is around 20 years. Around half of the cubs die before their first year from predation, often by adult male Kodiak bears. Adult sows tend to die from natural causes, while most adult boars are killed by hunters.

Most Kodiak bears build their winter dens in hill and mountain sides and will enter their dens in October. The males emerge around April, but the mothers with cubs will stay until June. Some males do not den but remain somewhat active during the winter. They have a small home range and are not territorial, and there is a great deal of overlap among the ranges of individual bears. This is attributed to the wide variety of foods available in the Kodiak Archipelago.
