Notes: A pleasant morning and not as windy as forecast in fact it was mostly calm. We started with a first net round of five including the only Blackcap of the morning and the first of several Goldcrest. The next capture of 11 included the first of two Song Thrush both probably immigrants and a Blackbird recapture ringed in 2012. The next round of 17 included the other Song Thrush and the bulk of the Reed Bunting capture that included one ringed in 2012 by Dave Hobley. Captures eased after this with just one more round of five and finally seven when taking the nets down including two Marsh Tit from B site.

Sightings 33 Species: Rather a lot of thrush movement including some high flying Blackbirds and a steady flow of Redwings. A flock of 40 Cormorants over indicates a good year; the fishermen will not be happy though. A big female Sparrowhawk soaring over the reed bed made us wonder but we could not get any detailed views. Two Swallows and the Chiffchaff and Blackcap captured reminded that the summer return passage is not quite over.
