Laughing gull

I've kind of plateaued on finding the uncommon passerine migrants so it was nice to pick up an easy Laughing Gull this evening.

I didn't have to wait long for beachwalkers to put the birds to flight.

 You can see how the black of the primaries grades smoothly into the charcoal gray of the upperparts.

Here's an old pic of Franklin's in flight from a few years ago.  The black in the primaries of Franklins cuts off much more abruptly, and is separated by the white trailing edge in addition.
