The docile behavior and diurnal habits exhibited by the island fox probably results from an absence of large predators and freedom from human harassment. Island foxes use auditory, visual and olfactory signals to communicate with one another. They can commonly be heard barking at night. Island foxes are agile tree climbers. Reproduction The Island fox reproduces once annually, and den in subterranean holes or in rock piles.
Juveniles are capable of breeding in their second year of life.
Diet Insects, rodents, birds, reptiles, and fruit. Predators Golden eagle, man. This diminutive relative of the gray fox is only found on the Channel Islands of California. This unique animal is listed as a threatened species by the state of California, and might be federally listed in the future. Because of interactions between a federally listed endangered bird, the San Clemente Loggerhead Shrike, a program to reduce the number of foxes on the island was instituted.
