Lakenheath Fen produced the expected Hobbies (40+) as well as Hairy Hawkers, Variable DFs and Four-spotted Chasers. We heard lots of Bitterns, but none obliged us with a fly-by!
Next stop (after lunch at Brown's!) was the clearing at the back of Grimes Graves, where we had very close encounters (but no photos!) of Tree Pipits and Woodlarks: several Willow Warblers looked down from the tree-tops.
Finally we walked the circuit at Santon Downham, where the best we managed was a very close Buzzard and a bees' nest in exactly the same tree as last year!
And finally: while looking for a Gropper at Lakenheath I saw this little Acro. (Last image) Probably just a worn Sedge, but I thought it looked pretty good for a Paddyfield Warbler..
