Skull Characteristics Temporal ridges weakly developed (<1 mm wide) and form a V. Similar to red fox, but smaller with more inflated auditory bullae. All foxes: Postorbital process concave.
Notes Subspecies found in Oregon is kit fox, V. velox macrotis. Some taxonomies split the swift fox (V. velox) and kit fox (V. macrotis) into separate species. The swift fox subspecies range is in the central plains east of the Rocky Mountains, while the kit fox range is in the southwest US and Mexico, north to southern Idaho and Oregon.
