Black-Headed or Bonaparte's Gull Central NJ (1 Viewer)

Is either one of these birds a black-headed gull? I've read up a bit on differences but I'm still not sure. Do Bonaparte's ever have red on their beaks at all or are they always black? Both the bird in flight and the bird on the water show some red. Thanks

They all look like Bonaparte's to me.

Black-headed gull has bigger bill and blackish underside to inner primaries.

Bonaparte's for me after doing a google search.

The “flesh pink” legs are a very good pointer.👍
