For example, the Arctic fox has a white coat in winter (containing little pigment), and a brown coat in summer (containing more pigment), an example of seasonal camouflage (a polyphenism). Many animals, including mammals , birds , and amphibians , are unable to synthesize most of the pigments that colour their fur or feathers, other than the ...

The color varies from pale grey to orange-brown and dark brown. [4] The American pine marten sports a reddish brown coat and an orange-tinted throat, but their numbers in the wild were depleted until after the turn of the century.
