Thanks, Will, for doing that. Are there notes and comments from observers? Also, do more photos exist? Impressions of leg color would be most helpful.
Identifying a bird from a single photograph is perilous, but here are my impressions. At first glance Slaty-backed Gull seems a reasonable suspicion. The dirty markings on the head and neck, apparent darkish around the eye, and overall head and body shape are ok for that. But, on closer look the steep gonydial angle and large, blob-ended bill, together with apparent pale leg color and dark upper back matching the nearby gull argue for 3rd year Great Black-backed Gull. At least in this photo the white edging of the tertials is not wide enough to suggest Slaty-back, but just right for Great Black-backed Gull. I look forward to seeing more images.

Great Black-backed Gull. The observers state that there appeared to be a noticeable and distinctive size difference. The bird was said to be comparable to Herring Gull in size. There are no pictures of the bird in flight. Pictures are at: http://groups.yahoo.com/group/hmbirds/photos/album/77752785/pic/296175519/vi ew?picmode=large&mode=tn&order=ordinal&start=321&dir=asc The location is at the Cohoes Flats - a section of the Mohawk River that separates Albany and Saratoga Counties. Access is tricky, but there are two public viewing areas overlooking the hydro-electric dam and downstream flats. If anyone is interested, I can provide access details. Thoughts?
