Several news outlets in Washington DC have responded to our report of coyote-wolf hybrids living there, including a flat-denial from the National Parks Service. They're wrong.
What they're not telling you is that the Eastern Coyote, the species of coyote that lives throughout the eastern seaboard of the US and Canada and has now made Rock Creek Park its home, came to be through cross-breading between smaller, western coyotes and larger, boreal and grey wolves. The species is, by its very definition a coyote-wolf hybrid. Eastern coyotes are larger than their western counterparts by roughly double, a not inconsequential size difference which enables them to predate larger species, including deer and, of course, your pets.
So, sorry Acting Deputy Superintendent Jeremy Sweat, but you're flat wrong.
