I don't know the research project you are referring to, but I will look around. I did find this one.

As far as "packs" go, I wouldn't conclude that just because I say 10 or 15 coyotes together, that they were an organized pack. They may just be together for a short period, or really large family group.
I have not been directly involved in any coyote research, so it is hard for me to say.
I know that on one of Byron's videos he has a scene with about 13 coyotes in a pasture at one time.
