Data on Eastern Coyotes

  Data on Eastern Coyotes

Relatively little information has been published on coyotes in the eastern United States, particularly the mid-Atlantic region, the last area to be colonized by coyotes. A new publication by NWRC summarizes what is known about coyote ecology in the mid-Atlantic states of Delaware, Maryland, North Carolina, Pennsylvania, Virginia and West Virginia. Below are some of the more interesting facts.

  • Coyotes began moving eastward from their historic range around 1900.
  • Reports of coyotes in the mid-Atlantic states were first made in northern Pennsylvania in the late 1930s.
  • Eastern coyotes are larger than their western counterparts and sometimes display melanistic (black) coats.
  • The largest recorded female eastern coyote weighed 25.1 kg/55 lbs.
  • Eastern coyotes have hybridized with eastern wolves and red wolves.
  • In 2005, 35,000 cattle and calves worth > $20 million dollars were lost to coyotes in the eastern U.S., three times the number lost in 1991.
