I had a crow die in my yard this week. This gave me an opportunity to study its plumage. I noticed primaries 8,7,6, were emarginated (leading edge is wider at the base than at the tip). I know that many flycatchers have emarginated primaries but I don’t know about other species. The real question though is: Why emargination of any primary? Why would it be variable from species to species?
