Now got full results of our Pied Flycatcher study. In total we had 141 occupied nests of these 121 successfully produced some young. This compares with 120 and 65 last year. Although we missed ringing a few broods we managed a record total of 722 nestlings 223 up on 2016. A total of 65 new adults were ringed and 113 adults retrapped. Most of these were birds first ringed in our area but we had two from Durham and one from North Yorkshire ringed as nestlings there, but now nesting in our woods.
There was little predation this year compared with 2016 when weasels played havoc in some woods. Perhaps due to this year being a good vole year. Brood size at ringing averaged 6.5 compared with 6.0 last year with 20 broods of 8 nestlings and one of nine.
Of the retrapped birds, 17 were 3 years old, six four years,one five and three six years.Interesting to see how many return to nest next year after this record year.
