very poor FOY record photo
観察結果の詳細
FOY and my earliest Golden area record by a week; despite the distance and viewing conditions I could identify these birds (versus Ring-billed Gulls which were also seen here) because of the relative darkness of their mantles (comparable to the California Gull they were near (photo)), the extensive white on their rumps (wide tertial crescent) and smaller patches of their backs (scapular crescent), and the lack of any ring on their small yellow bills (seen fairly well with my scope)
