Podrobnosti k pozorování

Subadult. A small, relatively short-billed and long-winged Iceland Gull. Mantle paler gray than usual thayeri. Was surprised on study of primary photos to find pattern largely diagnostic for kumlieni type, with no black on P5 and barely any on P6. Black tones and P10 generally grayish; M8 on Kodak scale. If kumlieni is actually a mass hybrid swarm bwteen glaucoides and thayeri, than this would seem to be on the thayeri end, but following the long-held parameters for assignment to this species, it nevertheless fits. The back color and gestalt seem right as well, though the resting primaries read rather dark.
