20th May - sunny, 23C, light breeze easterly

Todays plans changed when news came of an adult  White-winged Black tern at Eyebrooke reservoir.  It was sitting on a buoy when I arrived, then flew and fed with the common Terns present.  The distance and heat haze made for poor digiscoping.
A couple of Hobby were hunting overhead too.

Then news came of a possible Baird's Sandpiper on lagoon 4 at Rutland Water, such a rare bird could not be missed.  The bird was still present when I arrived but quite distant and the heat haze was bad, so I could not confirm its identity.  Later other observers claimed it was a Sanderling and so may remain unidentified.
Other birds present on looking around included a Great Northern Diver from the Lapwing hide; a drake Garganey and a Turnstone on the lagoon in front of the visitor centre.
