Question? What makes those black-headed gulls and not Bonaparte gulls?

Our view was quite distant and yours was much closer. In our case the two gulls with black heads were associated with 15 or so unmistakable Bonapartes in winter/immature plumage (dot behind eye, no black heads). We could not discern the bill color, except that it was darkish and any size difference was not obvious given the distance.
