Similar Species

  • Iceland Gull similar in adult plumage, but is smaller and more slender. American forms usually have dusky to dark markings in their wingtips. Juvenile Iceland Gull has completely black bill and is rarely pure white.
  • Glaucous-winged Gull has gray or dusky wingtips in all plumages. Young Glaucous-winged Gulls have wingtips nearly the same color as the back.
  • Albino gulls can be misidentified as Glaucous Gull. If a gull is pure, immaculate white, it is probably an albino; young Glaucous Gulls will have some light brown markings.
