Black-tailed Prairie Dog
This mammal is a species of ground squirrel, but they got the name “dog” due to their alarm bark. Prairie dogs use a range of vocalizations to communicate about predators. When a prairie dog detects danger, it will retreat to a burrow mound and give warning with a series of yips.
Brown Bear

Harbor Seal
Harbor seals can dive to depths of 500 feet (152.4 meters) but depths of up to 1,460 feet (446 meters) have been recorded. They can remain submerged for up to 30 minutes at a time. During the winter, the blubber layer can account for up to 30 percent of a harbor seal’s body mass.
North American Elk
Elk are the most vocal deer in North America. The calves bleat, the females squeal or utter sharp barks, and the males bugle when in rut (mating season). Bugling is used to attract mates and advertise territories during the fall rutting season and can be heard for long distances.
Badger
Badgers are fearless, feisty, solitary, nocturnal animals that spend much of their life underground. They are extremely fast, efficient diggers. They hunt underground and surprise their prey by digging directly into their burrows.
Grizzly Bear
Grizzlies can run up to 30 miles an hour. A mother grizzly bear is extremely protective of her cubs. Grizzly bears congregate together during summer spawning when the salmon runs upstream.
