Site description (2000 baseline)
A small island and surrounding waters in Mulroy Bay, County Donegal. The site has been extended since the previous pan-European inventory (Grimmett and Jones 1989) to include 18 ha of surrounding waters.

Key biodiversity
This site was formerly of importance for Sterna sandvicensis, holding the second-largest breeding colony in Ireland (180 pairs) in 1984, although more recently numbers have declined (with none breeding in 1995). The species may yet recolonize˜the birds that used to nest at the site are now believed to breed at Inch Lake (site 005). There are also breeding Sterna paradisaea (20 pairs, 1984) and a nationally important colony of Larus ridibundus (180 birds, 1984).
