Editing Coywolf (section)

==Description==
Hybrids of any combination tend to be larger than coyotes but smaller than wolves; they show behaviors intermediate between coyotes and the other parent's species.<ref name=mech2014>{{Cite journal | doi = 10.1371/journal.pone.0088861| pmid = 24586418|pmc=3934856| title = Production of Hybrids between Western Gray Wolves and Western Coyotes| journal = PLOS ONE| volume = 9| issue = 2| pages = e88861| year = 2014| last1 = Mech | first1 = L.

Despite being delivered by a female coyote, the hybrid pups at birth were much larger and heavier than regular coyote pups born and measured around the same time.<ref name=mech2014/> At six months of age, these hybrids were closely monitored at the Wildlife Science Center. Executive Director Peggy Callahan at the facility states that the howls of these hybrids are said to start off much like regular gray wolves with a deep strong vocalization, but changes partway into a coyote-like high pitched yipping.<ref>Riese, Clive (March 19, 2014), [http://forestlaketimes.com/2014/03/19/wildlife-science-center-partners-in-study-impacting-wolf-controversy/ Wildlife Science Center partners in study impacting wolf controversy], ''Forest Lake Times''</ref>

Compared with pure coyotes, [[eastern coyote|eastern wolf × coyote]] hybrids form more cooperative social groups and are generally less aggressive with each other while playing.<ref name="bekoff1978">Bekoff, M.
