- Rockabill
Rockabill (irish place name|Carraig Dábhiolla, Cloch Dábhiolla|Two-bill Rock) is an island (to be precise, two islands, "The Rock" and "The Bill"), lying in the western
Irish Sea about 6kilometre s east-north-east of Skerries,County Dublin ,Ireland . An alternative Irish name, "Carraig Dhá Bheola", meaning "Two Lips Rock", is probably just a corruption of Carraig Dábhiolla.The two granite islands are separated by a channel about 20
metre s wide. On the Rock there is alighthouse , built in 1855–1860 and automated in 1989, and several walls and outbuildings. These walled areas have enabled a build-up of soil and the establishment of vegetation, notably tree mallow ("Lavatera arborea "), which provides nesting cover for the birds. The smaller Bill has very little vegetation.Rockabill is an important
seabird breeding island, especially notable for itstern s. It is an internationally important site forRoseate Tern s, with the largest colony in Europe, over 600 pairs in 2003. There are similar numbers ofCommon Tern s, and other seabirds includeBlack Guillemot s andBlack-legged Kittiwake s.Rockabill is owned by the
Commissioners of Irish Lights and is aRefuge for Fauna and aSpecial Protection Area under theEuropean Union Birds Directive. Since 1989, when the protection afforded by the lighthouse keepers ceased, the islands have been managed byBirdWatch Ireland .External links
