SUBORDER : Lari (gulls and allies)

Note : under the recent reorganisation of the order CHARADRIIFORMES, the suborder Lari also includes the Crab Plover and the Pratincoles and Coursers from the Shorebirds families Dromadidae and Glareolidae, together with Skuas, Auks, Terns and Skimmers.

Family : Laridae, with 56 currently recognised extant species under 11 genera.

Subfamily : Larinae

Previously, most gulls were placed in the large genus Larus. However, following recent research and DNA systematic analysis, the family has been re-categorised resulting in the renaming of 22 species, which are now under the new genera Ichthyaetus, Leuophaeus and Chroicocephalus.

The smallest species is the Little Gull, and the largest the Great Black-backed Gull and then the Glaucous Gull.

About half of the world’s species have been recorded at one time or another in the UK.

The following is a complete systematic listing at genus level with information taken from various sources.
