Under the recent reorganisation of the large and diverse order CHARADRIIFORMES, the suborder Lari (gulls and allies) includes all the various species of gull, tern, skimmer, auk and skua, as well as certain shorebird species, notably those from families Dromadidae and Glareolidae (see Shorebirds).

Family : Laridae, with 56 (possibly up to 61 - see note below) currently recognised extant species of gull 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.

I've listed 56 species with notes regarding possible additions for the Mew Gull [Larus brachyrhynchus] and possible omissions for both the Kumlien’s and Thayer’s Gulls if treated as a subspecies of the Iceland Gull. In addition there are a further four subspecies, being the Kamchatka Gull [Larus (canus) kamtschatschensis], Steppe Gull [Larus (cachinnans) barabensis], Azores Gull [Larus (michahellis) atlantis] and Baltic Gull [Larus (fuscus) fuscus] where at least one authority believes that there is enough geographic variation to treat those birds as full species - hence a possible 61 species if all are counted.

This list is for personal reference, which is why certain species (just 19no) are highlighted – these being the species that I have both seen and photographed. Where possible, subspecies [ssp.] are defined for those particular birds.

  • Pacific Gull - Larus pacificus, [2 subspecies]
  • Belcher’s Gull - Larus belcheri, also known as the Band-tailed Gull

    [Greenland and western Europe, including UK and Iceland : ssp.graellsii]
