Ireland hosts five species of tern, migratory seabirds which breed on our coasts and inland lakes in the summer months before migrating to warmer climes in the winter. The roseate tern breeds in huge numbers on Rockabill Island, where the colony is vitally important to the species’ European population as a whole. Climate change and invasive species threaten our terns, but work is ongoing to protect them and ensure their breeding success.
