Thayer's Gull adult, December 22 2011, Duluth, Minnesota, US. Picture: Karl Bardon.

Visit: Karl's Pbase pages.

Distinct spot on outer web of P5 and complete sub-terminal band on P10. P10 with much black on inner web. Thayeri pattern on P9 combined with broad sub-terminal band. Medial band on P9 continues on inner web, and just covers the edge of the outer web at the mirror (P9 mirror on both webs).

Bird probably best matches (except for P5 pattern) option Plate 3-d.
