Foxes, with their pointed noses and long bushy tails, are familiar 
animals to most persons. The very shape of the head gives these 
creatures that aspect of cunning and sagacity for which they are 
eminently noted. Foxes are fond of solitude, and live alone in a 
burrow which each individual has dug for himself or appropriated by 
force from some other animal, the sufferer being frequently the 
badger. Sometimes a family may inhabit a single burrow, the dog 
Fox remaining with the mother after the cubs are born, and woe to 
the occupants of the hen coops in their vicinity while they remain in 
residence. Two genera of Foxes are recognized in North America, 
Urocyon and Vulpes, distinguished by the presence or absence of a 
hidden stiff-haired mane in the tail, and by some cranial characters.
