Episode 3: A Yellowstone Love Story


Black bear (also called the American black bear) – The black bear is the most common species of bear in North America. It ranges across most of the continent, from northern Canada and Alaska to Mexico and from the east to west coast. In many other places, black bears are usually black in color. In Yellowstone, only about 50% of black bears are black. The rest are brown or blonde in color. Scientific name: Ursus americanus.

Food conditioned – The response to a stimulus that occurs when an animal has learned to associate the stimulus with a certain positive or negative effect.

Grizzly bear
– A subspecies of brown bear that once roamed the mountains and prairies of the American West. Today, the grizzly bear remains in a few isolated locations in the lower 48 states, including Yellowstone. The name “grizzly” comes from the frequent presence of silver-tipped or “grizzled” hairs on the animals’ coats. Scientific name: Ursus arctos horribilis.

– In reference to hair or beard color, grizzled means partly gray or streaked with gray. Grizzly bears are so named because their fur often has silver tips.

– A learned behavior in which an animal exhibits a lessened response with repetition of a stimulus. Bears in Yellowstone have shown habituation to people and cars, meaning that they run away less or otherwise respond less to the presence of people or the passing of cars.

– The natural home where a species lives and grows.

Winnie the Pooh – A fictional bear created by A.A. Milne and popularized in a series of books and animated cartoons.

Yogi Bear – A fictional bear who appears in animated cartoons created by Hanna-Barbera Productions. The series is set in the fictional park of Jellystone.
