These birds breed on tiny lochans and feed on the sea or adjacent larger waters mostly north and west of a line from Glasgow to Moray. Numbers reduced 100 years ago by persecution and collecting but continuing increase and range expansion in Scotland with survey estimate of 935 pairs in 1994. Irish population apparently less than 10 pairs but stable. Breeding failures at the young stage have increased recently and are worrying but Shetland productivity is very weather dependant. Prospects seem good for further range expansion and filling in of gaps provided global warming does not degrade the conditions the birds require.
