Now though, visitors to South Stack on the north west tip of Anglesey can get a close-up view of the birds nesting thanks to an RSPB nestcam which beams live pictures from deep inside a rock crevice to the reserve's information centre.
The nesting antics of other well-known South Stack species such as guillemots, puffins and razorbills could also be caught on camera as spring progresses, according to the RSPB.
Elsewhere in Wales, a pair of choughs have been regularly nesting for many years at the Llechwedd Slate Caverns where visitors can watch live webcam link-ups right through until 17 July.
So with the bird world's version of Big Brother in full swing, who needs binoculars anymore, eh?
