Summary
[edit]DescriptionThayer's Gull 1425 (Larus thayeri).jpg |
English: Fremont, California . Adult.
I treat this taxon as a legitimate species following an excellent review of the Iceland Gull-Thayer’s Gull group by Weir et al. (2000) J. Zool. 252:517-530. A pdf of the article is found on Gull-Research.org. Unfortunately the American Ornithologists’ Union muddied the waters with its 2017 annual supplement to the AOU checklist, in which Thayer’s “became” a subspecies of the Iceland Gull. |
