Larus

 Herring gulls Larus argentatus, photographed by Ricky.

Belongs within: Larinae.

The genus Larus, previously used to include the majority of gulls, has often been restricted by recent authors to include the herring gulls and related species. These are larger gulls with white heads and grey or black backs. Taxonomy of the group has historically been complex with disagreement on the treatment of closely related forms at the species or subspecies level.

Members of the genus include a basal clade of large, mostly dark-backed species containing the Pacific gull L. pacificus, Belcher’s gull L. belcheri, black-tailed gull L. crassirostris and Olrog’s gull L. atlanticus; Olrog’s gull is found on the Atlantic coast of South America whereas the others are found around the Pacific ocean. Heermann’s gull L. heermanni is a distinctive species found on the west coast of North America with a medium-gray body, dark back and red bill.
