glaucoides - kumlieni

(last update: January 26, 2012)

Kumlien's / Thayer's Gull (kumlieni / thayeri) 1st cycle (1CY), December 22 2011, Canal Park, Duluth, MN. Picture: Karl Bardon.

First-cycle Iceland type gulls in Duluth during the fall/winter 2011-2012. This particular bird may represent intergrades/hybrids with Thayer's Gull, especially as it shows a solid tail band, some solid color in the tertials. However, there is no secondary bar and the outer primaries in flight are as pale as the rest of the wing.
