Two small, rocky islands approximately 7 km off the north coast of County Dublin. The lighthouse present on one island has been unmanned since 1989.
Rockabill is important for breeding seabirds and supports the largest breeding colony of Sterna dougallii
in the north-east Atlantic and, thus, in Europe.
Pressure/threats to key biodiversity
Since 1989 BirdWatch Ireland have, with NPW, managed the tern colony and there is presently very little disturbance.
