In reply to alexm198:

They don't really build nests, they lay in a scoop in shingle or just on bare rock. You can tell when you're close as they zoom around you making a complete racket, but not so close as to tell you when you're getting close to the egg if you know what I mean - I think they try to distract you more than anything. They'll do this at any time of day or night, they regularly disturb my midnight bass fishing sessions (even though I'm well below the high tide mark and nowhere near any nests).
I had the pleasure of seeing a gull chick hatching yesterday. Abbed past a ledge on a route and paused to look at something and noticed a quiet 'meep meep meep'. Looked and saw a gull's nest with two eggs, so carried on looking for a chick as they have a habit of wandering out of the nest but couldn't see one. Then saw a beak poking out one of the eggs . Quickly abbed away and chose a different route to climb back out. Hopefully the parents were brave enough to return past the ab rope, it was hanging well away.
