Our first Roseate Tern egg is in one of the boxes kindly supplied by Balbriggan Community College last year. So a big thanks to the students and teachers at Balbriggan Community College, as well as the Fingal Branch of Birdwatch Ireland, for their support.

Our first Common Tern eggs (there's two in seperate nests) are in one of the gardens beside the lighthouse. See the pictures below to get an idea of the work we had to do to get it ready for nesting! (Edit: We're now on three nests and counting...)

The birds had been settling down more every day at the start of the week, but the strong winds in recent days have caused some disruption again unfortunately. Interestingly, the Rockabill Terns tend to lay their first eggs around a week later than those at Ladys Island in Wexford, and this year was no exception. Over the course of the summer we'll have something like 2,000-3,000 Roseate Tern eggs and 4,000+ Common Tern eggs on Rockabill.
Things are about to get busy!!
