Juvenile red foxes are known as kits. Males are called tods or dogs, females are called vixens, and young are known as cubs or kits. [14] Although the Arctic fox has a small native population in northern Scandinavia, and while the corsac fox's range extends into European Russia, the red fox is the only fox native to Western Europe, and so is simply called "the fox" in colloquial British English.

The crab-eating fox was originally described as Canis thous by Linnaeus (1766), and first placed in its current genus Cerdocyon by Hamilton-Smith in 1839. [ 4 ] Cerdocyonina is a tribe which appeared around 6.0 million years ago (Mya) in North America as Ferrucyon avius becoming extinct by around 1.4–1.3 Mya. living about 4.7 million years .
A silver fox. The silver fox, sometimes referred to as the black fox, [1] or blue fox, [2] is a melanistic form of the red fox (Vulpes vulpes). Silver foxes display a great deal of pelt variation. Some are completely glossy black except for a white colouration on the tip of the tail, giving them a somewhat silvery appearance.
A fisher's hunting range varies from 6.6 km 2 (3 sq mi) in the summer to 14.1 km 2 (5 sq mi) in the winter. Ranges up to 20.0 km 2 (8 sq mi) in the winter are possible depending on the quality of the habitat. Male and female fishers have overlapping territories.
In areas such as Primorsky Krai and their introduced range, common raccoon dogs hibernate only during severe snowstorms. In December, their physical activity decreases once snow depth reaches 15–20 cm (5.9–7.9 in), and limit the range from their burrows to no more than 150–200 m (490–660 ft).
The gnatcatchers are mainly soft bluish gray in color and have the typical insectivore's long sharp bill. Many species have distinctive black head patterns (especially males) and long, regularly cocked, black-and-white tails. One species has been recorded in Michigan.
