They occur in shades of greens or browns and can change colors over periods of hours and weeks. less ↑

Pituophis catenifer is a species of nonvenomous colubrid snake endemic to North America. Six subspecies are currently recognized, including the nominotypical subspecies, Pituophis catenifer catenifer, described here. This snake is often mistaken for the prairie rattlesnake but can be easily distinguished from a rattlesnake by the lack of black and white banding on its tail, and by the shape of its head which is narrower than a rattlesnake's. less ↑

The black-tailed jackrabbit (Lepus californicus), also known as the American desert hare, is a common hare of the western United States and Mexico, where it is found at elevations from sea level up to 10,000 ft (3,000 m). Reaching a length around 2 ft (61 cm), and a weight from 3 to 6 lb (1.4 to 2.7 kg), the black-tailed jackrabbit is the third-largest North American hare. Black-tailed jackrabbits occupy mixed shrub-grassland terrains. Their breeding depends on the location; less ↑

The California ground squirrel (Otospermophilus beecheyi), is a common and easily observed ground squirrel of the western United States and the Baja California Peninsula; it is common in Oregon and California and its range has relatively recently extended into Washington and northwestern Nevada. Formerly placed in Spermophilus, as Spermophilus beecheyi, it was reclassified in Otospermophilus in 2009 as it became clear that Spermophilus as previously defin less ↑

The dusky-footed woodrat (Neotoma fuscipes) is a species of nocturnal rodent in the family Cricetidae. They are commonly called "packrats" or "trade rats" and build large, domed dens that can reach several feet in height. Coyotes and other predators will attempt to prey on these rodents by laying waste to the dens, but the sheer volume of material is usually dissuasive. Occasionally, dusky-footed woodrats will build satellite dens in trees. Although these animals are religiously sol less ↑

The bighorn sheep (Ovis canadensis) is a species of sheep native to North America named for its large horns. These horns can weigh up to 14 kg (30 lb), while the sheep themselves weigh up to 140 kg (300 lb). Recent genetic testing indicates three distinct subspecies of Ovis canadensis, one of which is endangered: O. c. sierrae. Sheep originally crossed to North America over the Bering land bridge from Siberia; the population in North America peaked in the millions,... less ↑

The gray whale (Eschrichtius robustus), also known as the grey whale, gray back whale, Pacific gray whale, or California gray whale is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9 meters (49 ft), a weight of 36 tonnes (40 short tons), and lives between 55 and 70 years.

The short-beaked common dolphin (Delphinus delphis) is a species of common dolphin. It has a larger range than the long-beaked common dolphin (D. capensis), occurring throughout warm-temperate and tropical oceans, including the Indian Ocean although in smaller quantities than other places they are found. There are more short-beaked common dolphins than any other dolphin species in the warm-temperate portions of the Atlantic and Pacific Oceans. It is also found in the Caribbea less ↑

The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere.

The bobcat (Lynx rufus) is a North American cat that appeared during the Irvingtonian stage of around 1.8 million years ago (AEO). Containing 12 recognized subspecies, it ranges from southern Canada to central Mexico, including most of the contiguous United States. The bobcat is an adaptable predator that inhabits wooded areas, as well as semidesert, urban edge, forest edge, and swampland environments. It remains in some of its original range, but populations are vulnerable to local less ↑

The coyote (Canis latrans); from Nahuatl  pronunciation (help·info)) is a canine native to North America. It is smaller than its close relative, the gray wolf, and slightly smaller than the closely related eastern wolf and red wolf.
