Somewhat of a sad scene seeing this poor thing. Mange has been a problem among the Coyote population in this particular area for a number of years and continues today. Sadly there is nothing that can be done to treat it – they simply recover or, more often than note, perish over time. This particular one was patrolling a prairie dog colony northeast of Denver, Colorado hoping to find a meal. It actually looked better than some others I have seen.
Coyotes are amazingly adaptable animals and have not been greatly impacted by human expansion. Here in the area I live, this has resulted in some human – coyote conflicts, mainly with the coyotes attacking domestic pets. They range across North America and some have even been seen into Central America and Panama.
