Brown bears are the largest land predators in North America, with males averaging 5-6 feet tall and weighing 600-1,500 pounds. Some individuals can reach up to 8 feet tall and weigh over 1,500 pounds.
Black bears are smaller than brown bears, with males averaging 4-6 feet tall and weighing 200-600 pounds.
However, there are some exceptions:
* Kodiak bears, a subspecies of brown bear found on Kodiak Island in Alaska, are the largest bears in the world, with males averaging 7-10 feet tall and weighing 1,000-1,500 pounds.
* Polar bears are also larger than black bears, with males averaging 7-8 feet tall and weighing 800-1,500 pounds.
In general, brown bears are bigger than black bears, but size can vary depending on the subspecies, individual, and geographic location.
