Great job! You know your foxes well!
Red foxes are more abundant than were previously thought in the Greater Yellowstone Ecosystem; a fact that could be attributed to the growth of the wolf population. This is because wolves successfully competed with coyotes after their reintroduction to the region, causing a decline in the coyote population. This may have caused an increase in the number of foxes in the area since coyotes compete more directly with the smaller canid.
