There is a GRASSHOPPER WARBLER reeling at Olney Meadows just to the left of the pond; also there were 4 Northern Wheatears earlier at CMK , including a cracking male Greenland bird (Rob Hill)
My meagre efforts involve nothing at Willen North, other then 2 Whitethroats; 2 CUCKOOS and a HOBBY at Linford , 30+ Barnacle Geese at Emberton Park , including at least 8 birds sitting , 1 GARDEN WARBLER there also.
A freshly dead Common Tern was a sad find at Furzton (Simon Nichols)
