Loch Skerrow

Mark Humphreys says: "I may be mistaken but I believe I saw a Bar-headed Goose with two goslings on Loch Skerrow today. Do they interbreed ? It was at a distance, but the white neck and marked head appeared undeniable." 

Ed. Probably a Canada-Greylag hybrid. Bar-head? Nay! Feral escapee maybe.
