Taxonomy

Larus glaucoides

, 1822,

Iceland

.

Formerly listed as L. leucopterus. Closely related to L. argentatus, and in past sometimes treated as conspecific. Taxonomic position of birds formerly recognized as race “kumlieni” still problematic: has exceptionally been considered a separate species, as birds with grey wingtips occur alongside those with white wingtips in Nearctic; on the other hand, current tendency (followed here) is to treat it as a glaucoides × L. thayeri hybrid. E–W cline apparent, from pale glaucoides to slightly darker “kumlieni” to darker L. thayeri. Tendency to lump L. thayeri with L. glaucoides now accepted. Two subspecies recognized.
