The puffins are among an array of endangered birds that make Rathlin Island such a special place to visit each spring and summer.
But like so many across these islands, the red-listed species faces a series of threats from people and other wildlife.
So we headed along to Rathlin Island with RSPB NI for a behind the scenes look at their West Light Seabird Centre - and to learn about what's being done to help puffins as well as vulnerable kittiwakes, razorbills, fulmars and guillemots they share the island with every year.
