Afetr his exceptional May Waxwings yesterday at the filter beds, Dan B scored again with the first Black Terns of the year. A duo over the Low Maynard. I got a text whilst on the Bus home (thanks Lol) but was soon scoping them, albeit at vast range, from the bottom of Coppermill Lane, having been tipped off that they were on No.4/5. They had returned to the Low Maynard but were emminently doable. Pretty much annual, but never lingering for long, this is one species I didn't want to miss.
