I think Sanderling was the first shorebird I positively identified. I must have been about 11 or 12 (?) and I remember seeing this small white wader running around on Blackpool Beach on a cold wintry day. Afterward I went to my Great-aunt’s house nearby and she had a copy of ‘The Hamlyn Guide to the Birds of Britain and Europe’ and I found the Sanderling in there looked just like the one I’d seen earlier.
And here we are 40 years later.
