This is a group of five offshore islands with outlying rocks and reefs, 3 km south-west of the Mullet peninsula in County Mayo.
Key biodiversity
These islands support important numbers of wintering geese and breeding seabirds. Seabirds breeding in numbers of national importance are Phalacrocorax carbo (185 pairs, 1981), Fulmarus glacialis (500 pairs, 1981), Larus canus (20-50 pairs, 1981) and Larus argentatus (300-400 pairs, 1981).
Pressure/threats to key biodiversity
The site is a proposed (by NPW) Special Protection Area (Duvillaun Island, 446 ha), and should be designated in the near future.
