To clarify a few points in my earlier [rushed] message...
1. The bird was a 1st winter bird. Not a juvenile.
2. There was no noticeable difference is size between the Laughing and the
Black-tailed. That�s why �I can�t say that I noticed that it was bigger�
(LAGU is 16.5�, BTGU is 19� and a HEGU is 25�)
3. I neglected to mention the solid white rump.
My annotated original message reads:
> While at Fort Armistead Park at 12:00, I noticed a very dark gull flying

> spots on the primary tips. Dark wing linings. [3]

> After checking Sibley at home I want to add the following: This bird was a [1]
