Fox News reports a coyote attack on a two-year old girl in California. The story says that reports of coyote attacks are rare. Actually, unheard of until recently. However, like many animals, they are losing their fear of humans. And since coyotes have done very well in human inhabited areas, this is not a case of encroachment, such as often argued for bears and cougars.
This isn't the first such incident in Orange County. In September 2012, an Irving man reported being stalked and charged by a coyote, whom he believes was after his 1 year old son. (See also this warning from the City of Irvine).
