What is causing the increase in coyote attacks on humans?

Coyotes are now found in every state except for Hawaii.  But, where sightings were once uncommon, they have become routine.  They once only lived on the plains, but are now found in even in large cities like New York City, Chicago, and Denver.  This is where the problems normally occur.

Coyotes once avoided contact with humans, but many believe that the ever expanding suburban sprawl is invading the coyotes territory.  Wolves were the coyotes' primary competition for food sources, but the wolf has been driven back where the coyote has adapted.

Arguments abound over whether coyotes no longer fear humans.  They seem to have learned that people do not pose a danger to them.  Most people no longer shoot at the predators as they once would have.  This makes them much less likely to avoid humans.  But, some people don't think that means that they are more aggressive towards humans.

But, there have been several cases of coyote attacks on humans lately and often it is right in the people's neighborhood in town.

Coyotes have been known to enter fenced yards and kill dogs or cats.  They have even taken them right from the owner who was walking them.

While people don't normally get seriously hurt, they would have to undergo a series of rabies shots if bitten by a stray coyote.  And, with an animal that may hunt in a pack, it may only be a matter of time before a serious injury occurs.

They are not a big animal, but a pack of them might be cause for concern.

If you encounter a coyote, it is best to yell, throw rocks and appear unafraid.
