This Eider was photographed recently at Malin Head by Ian Dickey. When Ian looked at his photos he thought to himself mmmmmhhhmmmm what have we got here! It certainly is an interesting Eider and may well be the Borealis Eider that Ronan McLoughlin found and photographed earlier in the winter. Unfortuneatly the sails are not present in these photographs but the colour of the bill strongly suggest this is a Borealis Eider or at least has Borealis genes. Check the third picture in the excellent article on Eiders below.
Thanks to Ian for some great photos, Eiders are fantastic birds anyway!
