The bobcat population has seen decline in the American Midwest, but is generally stable and healthy.

Fossil skull of Pleistocene North American jaguar (Panthera onca augusta)
The head of the jaguar is robust and the jaw extremely powerful. The size of jaguars tends to increase the farther south they are located.
A melanistic jaguar is a color morph which occurs at about 6 percent frequency in populations.
The jaguar inhabits a variety of forested and open habitat, but is strongly associated with the presence of water.

Cinnamon-colored black bear eating dandelions in Waterton Lakes National Park
American black bears can be distinguished from brown bears by their smaller size, their less concave skull profiles, their shorter claws and the lack of a shoulder hump.
Some specimens may develop a white " crescent moon" mark on the chest. This white mark, which is constant in Asian black bears, occurs in only 25% of American black bears. [15]
