Four rare roseate tern chicks have hatched on The Skerries off the coast of Anglesey.
It means the island is now host to the largest number of chicks for 29 years.
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.
