Thayer's Gull
Larus thayeri
The Thayer's Gull was once considered a slightly smaller sub-species of the Herring Gull, and is very similar. Its status is still in question, with some still considering a race of Herring Gull, and others calling it and the Iceland Gull different races of the same species.
Habitat: Summer habitat is rocky island coasts in the Arctic. Winters primarily along coastal areas, including areas well offshore. Will forage inland from the coast, but rarely found well inland.
Diet: Wide variety of items, including fish, squid, crustaceans, eggs and young birds, berries, carrion, and refuse.
Breeding: Non-breeder in South Dakota.
Song: Familiar gull's kee-yow
Migrations: Summers in high Arctic. Most winter along the Pacific Coast. Rarely ventures inland.
Similar Species: Herring Gull, Glaucous-Winged Gull, Iceland Gull. See Identification Tips.
Status: Numbers stable.
