Riding the storm, two birds of marvellous otherness

Borth y Gest, Snowdonia I've seen glaucous gulls squabbling around rubbish-tips on Baffin Island, but never before in Wales

Recent winter storm-surges from the cold north brought with them surprising visitors. Walking the coast path westwards I looked up and studied a clamorous swarm of gulls, vivid against a gunmetal sky. One, singled out in my glass, was bulkier than its companions, translucent somehow in the subdued light, its long wings white-fringed - a glaucous gull, Larus hyperboreus.

I've seen these fine seabirds before, squabbling around rubbish-tips at Iqpiarjuk and Pangnirtung on Baffin Island; or bathing in turquoise pools atop icebergs in the Davis Strait; or following the boat in which I crossed Admiralty Inlet when bound for the Brodeur Peninsula in quest of narwhal. Until now I'd never had a clear sighting of one in Wales, though it's merely uncommon rather than rare as a visitor here.
