BEACH walkers have reported up to 20 dead seabirds on Yellowcraig Beach as the Scottish Seabird Centre appealed for people to watch for any stranded birds.

The discovery of the young gannets, known as gugas, came last week after a sudden weather change caused problems for them after they had left their nests.

Gugas jump from their nests on the Bass Rock at about 12 weeks old into the sea below.

But they have to float for several days until they lose enough weight to fly and rely on the sea remaining calm during that period.

Tom Brock, chief executive of the seabird centre, said: “We have had a few reports of people finding seabirds washed up on the beaches in and around North Berwick.

“At this time of year, and with the change in weather, it is likely that these will be juvenile gannets, known as gugas.

“After leaving their nests on the Bass Rock, the young gannets, heavier than the adults and unable to fly until they lose weight, will float on the sea for several days.

“No longer under the care of their parents, their last meal would have been in the nest and this can mean that they have not fed for several days. Weakened, and in tough weather conditions, sadly many get into difficulties.” The Bass Rock is the largest single island gannet colony in the world.

Mr Brock urged people who find any gugas in distress on the beach not to approach the birds, but to call for help instead.

He said: “Tens of thousands of gugas will be leaving the Rock in September and October and members of the public who spot live gugas in distress are asked to keep their distance and to ensure that dogs do not get close.

“They should contact the seabird centre on 01620 890202 or the Scottish SPCA on 03000 999 999.” For more info about the gannet colony visit www.seabird.org
