A few bits and pieces from north Bucks today.
Newton Blossomville STW: 2 COMMON RAVEN over west, circling low, cronking away - excellent!; also 2 Marsh Tits
Olney Meadows: no sign of Gropper, but 1 HOBBY performing well
Ravenstone STW: 2 Yellow Wagtail, 1m Grey Wag
Tyringham Bridge: 2 Common Tern
Linford: 1pr Eurasian Wigeon, 1 LRP, 1 Cuckoo
Also quite a few Common Whitethroats about, looks like they've finally arrived in numbers; plus smaller numbers of Lesser 'throat, but still present at every site I visited. A couple of Garden Warblers were at Linford, where thankfully Reed Warbler numbers are up (if only to 3!). Sadly, Linford is still the only site I've heard Cuckoo (Rob Hill)
