Broadhead,
Most of the coyotes on our property are that color, except for one which is blond. We thought maybe the blond one was offspring of our dog (<img src=icon_smile_big.gif border=0 align=middle>), but I can't believe they're
all crosses, so I searched for some info about it and found this:

How can I identify an eastern coyote?
The eastern coyote is larger than its western cousin - typically attributed to wolf-coyote hybridization - and usually has one of four pelt colorations: tri-color (German shepherd-like), red, blond and dark brown (appears black at a distance). Adult males weigh 45 to 55 pounds; females, 35 to 40 pounds. When seeing one for the first time, many people mistake eastern coyotes for dogs. Look for black lines running up and down the front of the front legs, yellow eyes and a cylindrical-shaped, low-hanging tail. Adult coyotes are much larger than foxes, and they tend to travel trails, dirt roads and habitat edges.
What is a "coydog?"
The word coydog is used to describe a coyote-domestic dog hybrid. Coydogs were once believed to be found in good numbers in Pennsylvania, especially when our once-expanding coyote population was thought to be having difficulty finding same-species mates. Truth is, most of these so-called coydogs were probably coyotes or feral dogs, since the breeding cycles of dogs and coyotes are not synchronized. Studies have confirmed coyote-dog interbreeding rarely happens. If it was occurring regularly, it stands to reason that we'd be seeing coyotes with domestic dog-like characteristics such as spots, curly tails and floppy ears. In addition, it's likely that red and blond coyotes were mistakenly identified as coydogs in the past simply because their coats were not of the more common tri-color pelage. <hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face='Verdana, Arial, Helvetica' size=2 id=quote>

It's an interesting article, but I disagree with their theory that coyotes aren't affecting the deer population. (At least, I've seen evidence to the contrary on our property.)
