Gus is a North American Grizzly Bear. At the moment he is quite small, but one day he will be HUGE! A big Grizzly can weigh as much as a small car. Male grizzly bears, like Gus's dad, usually weigh around 200 kilograms, as big as a sumo wrestler. Gus was born in January. It is important to stay warm, so Gus and the family stayed in the underground den until April. Gus is still living with his mum and his brother Gil. Bears eat everything humans eat -- and more. Three quarters of their diet is fruit, berries and grasses, but they will eat pretty much anything. Eat and sleep, sleep and eat... Not a bad life for a Grizzly Bear!
