Scaup

The flock of Scaup wintering in Loch Indaal has declined very sharply in recent years, from 1000 to 1500 only 10 years ago to no more than 200 to 300 in the last few winters. And the reason is almost certainly the stopping of the distillery discharges from Bowmore and Bruichladdich, which no longer provide nutrients for the shellfish which form the main diet of the Scaup. One can't really argue against the removal of pollution from Loch Indaal, even one which is not that harmful to wildlife and actually beneficial to some, but it's a pity in a way that it has had this particular effect.
