Four rare roseate tern chicks have hatched on The Skerries off the coast of Anglesey.

The Skerries is a group of small rocky islets which lie just off the northwest corner of Anglesey. Its sparse vegetation and rough terrain mean it is inhospitable to humans. However, the RSPB says the islands are an extremely important sanctuary for nesting seabirds, especially terns.

Roseate terns have long tails, and pale feathers with the slight rosy flush that gives them their name. These endangered birds, affectionately called "rosys", fly each spring from western Africa to nest at just a handful of coastal spots in the UK and Ireland.

The arrival of these chicks is thanks to the dedicated RSPB staff who have worked hard to protect the seabirds on the Skerries over many years. Roseates like to have other types of terns for company, and the success of a single pair in 2018 and two this year shows they are being attracted to the thriving colony that our wardens have nurtured. The future here looks rosy for the rosys!
