Other Site Characteristics

The site comprises a group of uninhabited marine islands, rocks and reefs, located between 1 and 5 km off the southern tip of the Mullet Peninsula in Co. Mayo. The surrounding seas to a distance of 200 m from the shoreline, where seabirds forage, bathe and socialise, are included in the site. Duvillaun More is the largest of the islands, rising to 63 m, with cliffs on the north-west, west and south-west sides. About two-thirds of this island is covered by a maritime grassland sward. There is a small area of dry heath at the west end of the island near the summit. Duvillaun Beg, which rises to 14 m, also has a grassy sward and an extensive intertidal shore. The other islands, while having some land above the high tide mark, are largely rocky islets and knolls. From west to east, the lesser islands are Turduvillaun, Shiraghy Islands, Drumacappul Islands, Orragoon Island, Keely Island, Gaghta Island and Leamareha Island.

4.2 Quality and importance

The site is an important seabird colony, with nationally important populations of Hydrobates pelagicus, Fulmarus glacialis and Larus marinus. In winter, the Duvillauns support Branta leucopsis - up to 500 birds can occur; these are part of a much larger population centred on the Mullet Peninsula and Inishkea Islands. The site is a traditional nesting location for Falco peregrinus and 1-2 pairs of Pyrrhocorax pyrrhocorax breed. The Duvillauns form part of a larger group of islands, which hold one of the largest breeding populations of Halichoerus grypus in Ireland, a species listed on Annex II of the E.U. Habitats Directive.
