觀察細節

Nice! Small gulls with striking black wedge on outer primaries, white triangle on trailing edge, and dark mantle. Pretty sure I saw a dark band on the tail, so most likely juveniles. Made two foraging flights between the end of Webster and 520, low over the water. First seen at 10:20, last seen heading north on the main lake sometime around 11:45, scoped from K2. Alec and Dave R made it down in time to catch the second pass. Montlake Fill's second record.
