re: *** SPAM 10: Re: [cobirds] Re: Little Gull flyby Adams County

Nick...I bow to your expertise, but...
 
   the arcs are classic Franklin's
 
   the bill size, as you note, is Franklin's, not laughing
 
   ?

While body shape and bill size look good for Franklin’s, the wingtip pattern (lacking significant white in outer primaries) and adult head pattern favor Laughing Gull. A first summer Franklins gull should not have a full black head, and an older Franklin’s Gull would have extensive white in primary tips. interesting bird.

Thanks Steve. It was a lucky shot in the rain.

Two iNaturtalists and the Gull Watchers group have tag it as a Little Gull.

HOWEVER, you make a good arguement for a Franklin’s gull - I'm open to changing the ID.

Gary,

Among other things, a little gull in breeding plumage would lack the eye arcs seen on the bird you photographed. This one looks like a better fit for Franklin’s gull to me. Nice capture!

Happy Birding,
