As every recent overflying Buteo has morphed under focussing to a juvenile Herring Gull, so every recent flypast Common Tern has unseasonally morphed under focussing to an adult Black-headed Gull (see winter birds on previous post).
I had only the briefest of visits yesterday but the flypast Common Tern remained a Common Tern. Bravo! Year tick 61 in the bag. Only three more (House Martin, Sandpiper spp, and Goldcrest are the likeliest) and I'll beat the 2009 list - and there is still another 7 months of patch drudgery to go! Hurrah!
A Med Gull doing blimey I havent seen one of those for ages.
