Bear Color Morphs

Glacier Bear Ursus americanus emmonsii Possibly the most impressive color morph of the black bear, is the blue. Black bears come in more colors than any other North American mammal. They can be black, brown, cinnamon, blond, blue-gray, or white.

Glacier Bear with cubs East of the Great Plains, nearly all are black. These were the first bears early settlers saw, hence the name. The melanin in black fur makes the fur resistant to abrasion in the brushy understory of eastern forests.

In forested states. SUMMARY Color variation is a frequent evolutionary substrate for camouflage in small mammals but the underlying genetics and evolutionary forces that drive color variation in natural populations of large mammals are mostly unexplained. The American black bear, Ursus americanus, exhibits a range of colors including the cinnamon morph which has a similar color to the brown bear, U.

arctos, and. Scientists have long understood that colour variations, otherwise known as colour morphs, in small mammals are an evolutionary method of hiding from predators. 2 However, they are just beginning to understand why larger animals, such as the black bear, have colour variations 2.

What are the different types of black bear color morphs? The American black bear exhibits several color morphs, including black, brown (cinnamon), blonde, and blue-gray (glacier bear). In 1987, a researcher from Manitoba named Dr. Richard Rounds published a seminal paper comparing decades of regional reports about black bear color distribution with contemporary surveys from biologists and outfitters.

In total, they examined over 40,000 records of harvested or tagged bears and documented the percentage of black and non-black morphs, the latter being a collective term for all. Here, we show that the cinnamon morph of the American black bear shares phenotypic similarity with brown bears in their coat coloration, and we demonstrate that eumelanin dilution causes this similarity. However, color phase black bears range widely from jet black to chocolate, blonde and even cinnamon or grey color phases.

So, if you're after a color phase black bears, you need to go bear hunting in the right area. Color variation is a frequent evolutionary substrate for camouflage in small mammals, but the underlying genetics and evolutionary forces that drive color variation in natural populations of large mammals are mostly unexplained. The American black bear, Ursus americanus (U.

americanus), exhibits a range of colors including the cinnamon morph, which has a similar color to the brown bear, U. Scientists have been investigating why some black bear populations are exhibiting these unusual coat colors. Reports of Color Morphs While black is the most common color phase, black bears can display a variety of coat colors including cinnamon, chocolate, blonde, blue-gray, and even white.
