June 2016 - Fieldfare leg found at Tawny Owl nest

260 new birds of 24 species were ringed in June of which 41 were pulli. Last June, when three more sites held sessions, 319 birds were ringed but with an earlier fledging season only 18 pulli ringed.

CES sessions at Bedfont and Wraysbury are both running slightly above their 5-year mean indicating good over-winter survival of adults. As expected, Blue Tit was the most-ringed species with 45 (22 pulli) followed by Long-tailed Tit with 35 and Reed Warbler with 32.

Tythebarns provided a Stock Dove and 3 Jackdaws and Wraysbury some out-of-season Goldfinch. 

Some interesting recoveries were received including: a Fieldfare in Sweden (1,618 km from us) - its leg (and ring) found in a Tawny Owl nest site; a Reed Warbler, ringed 5 years ago at Bedfont recaptured at Frimley Station Lakes; and a Blackcap ringed near Wokingham 5 years and 9 months ago and recaptured near Wraysbury.
