In flight, with four American Avocets on the water below and two California Gulls in the background. Note dark terminal band on tail and minimal white spots in primaries, indicating a subadult bird.
觀察細節
Distinguished from California Gulls by smaller size, slimmer shape, lighter mantle, and in closer photos the black bill ring without visible red. This was the only Ring-billed Gull I was able to find; all the other gulls close enough for me to identify them were California Gulls. The Ring-billed Gull acted aggressive toward the other nearby birds at one point; I didn’t notice such behavior from any of the California Gulls.
