Tree climbing behavior is rarely observed among the Canidae and has not been observed in kit foxes (Vulpes macrotis). While conducting another behavioral study in Bakersfield, California in November 2002, we observed kit foxes climb trees on 2 occasions. Our observations demonstrate that kit foxes are capable of climbing trees and of agile mobility among tree branches. Our observations also provide an example of the behavioral plasticity of kit foxes, a characteristic that might contribute to their ability to successfully inhabit anthropogenically altered environments.
