One first cycle Iceland Gull and one presumed Nelson's Gull (Glaucous 
Gull X Herring Gull hybrid - I think first cycle because of iris color 
but distance made it difficult) joined the mass of gulls at Jug Bay this 
afternoon. When I first arrived at Jackson Landing around 3:30, the 
gulls were fairly close to the Prince George's shoreline, but as the 
tide came in, the little remaining ice was soon covered and the gulls 
moved further away, next to the Anne Arundel shoreline. I didn't get 
much time to estimate the size of the flock, but there were at least 
1,000 Herring Gulls and 500 Ring-billed Gulls. At least three Lesser 
Black-backeds were also present (1 ad., 2 1cy.). I've posted a couple 
photos of the presumed Nelson's Gull on my Flickr page:
