Birds

On islands at the western end of the lagoon, there is an important tern colony, with the only breeding Sandwich Terns in Wales; Arctic and Common Terns breed here regularly but Roseate Tern now only occasionally. For this reason Cemlyn has been designated as part of a Special Protection Area along with two other nearby sites, Ynys Feurig and The Skerries, and all three are also classed by Birdlife International as an Important Bird Area. Birds interchange regularly between all three sites, and form part of a larger Irish Sea tern population together with birds at sites in Ireland such as Rockabill Island. The tern colony is wardened from May to August.

Cemlyn has attracted a number of vagrant birds. It is most famous among twitchers as the site where a Bridled Tern spent several weeks in July 1988, and where the similarly rare (in a British context) Sooty Tern was present on and off in July 2005. Both species had at these times been seen by only a very small number of birders in Britain. Also at Cemlyn in 2005 were an American Golden Plover in May and a Terek Sandpiper in June. In 1998, an Isabelline Shrike was present for most of the month of July.
