I think your zoology is a bit off and the type of coyotes you refer to, and the behaviors you describe are pretty much standard issue for any coyote pack.

C. latrans is the species of coyote - there are subspecies beyond this, but the Coywolf is not one of them.

Coywolf simply refers to the phenotype observed when coyotes and wolves interbreed - this can happen anywhere between all of the wolve and coyote subspecies. Coywolves are almost “one offs” (breeding pair hooked up by chance). Many wolves also have coyote DNA.
