Second cycle. Small to medium sized gull (about Ring-billed Gull size was my first impression; was surprised to see the face patch) with solid black outer primaries, a dark patch behind the eye, and a uniformly dark, fairly thick and long bill. The black "armpit" patch on the underwing, which Laughing Gulls show from first summer up to second winter in some cases, also helps distinguish it from Franklin's Gull, which shows white there. Franklin's Gull also typically shows more extensive dark head markings. The review team reached out to Amar Ayyash, who supported the ID of a second cycle Laughing Gull. Flew north over 1918 Marsh at 8:44pm, about 15 minutes after sunset, may be roosting in the soccer field next to the marsh (FRGU has roosted there with RBGU previously, so that would be my first place to check for refinding) or on Lake Mendota (this spring I've seen some gulls roosting on the water north/northwest of Frautschi Point, usually very distant).
