The ground nesting habit of this species makes it particularly susceptible to predation by mink, which explains its disappearance from many Argyll islands, including Iona. At other sites, shortage of its main prey species, sandeels, has been blamed for its disappearance.

The largest NTS colony is on Fair Isle with 1,250 pairs. In some years, breeding success is severely hampered by shortage of sandeels.
