Dave Francis concluded the Constant Effort Site bird ringing survey for another year at Pitsford Res this morning. All the early indications are that this year was much better than last year in respect of young bird productivity. A good example was today's effort which saw 66 birds being caught, of which it was assessed that 62 of them were hatched during this calendar year. Late brood Wrens and Bullfinch made up the larger numbers of the catch today (Bullfinch is traditionally a late breeder). Other birds caught included 7 Reed Warblers (lots of young birds moving through the site this year), a Sedge Warbler, 6 Blackcaps, 3 Whitethroats, a Garden Warbler, a Willow Warbler and 3 Chiffchaffs.
A heavy Swallow passage was evident overhead in the county today with good numbers passing south all day. Another hundred or so birds have been caught by John Woollett and team at the reed bed roost at Stortons GP during this week, in addition to the birds caught last week.
An evening meander around Harrington Airfield this evening didn't provide much of note but there was a single Wheatear by the straw bales on the concrete track and common raptors provided good views.

Big birds over
