Wraysbury GP - 13th July 2017

A mid-week morning session with just CL and DKL and seven nets. We continue to hope for recaptured Whitethroat data to enable us to continue with the RAS, now in its third year. There was certainly less Whitethroat song and fewer nesting pairs this year after so much bramble was removed early in the year.

Three birds (female Z761972 ringed as a 5F on 28th April 2016, D859524 a 4M ringed as a 3J on 27th July 2014 and  female Z072799 ringed when a 3J on 10th July 2015) contributed to the study.
Several young Whitethroat, trapped earlier in the summer had also remained in the area.

D859524 4M Whitethroat (hatched 2014 actual 9M using data)

Z761972 4F Whitethroat (hatched 2015, actual 7F according to data)

We also recaptured a 6M Bullfinch D710480, ringed on 1st April 2014 as a 6M. The bird had some form of infection, possibly avian pox, with growths around the beak. Necessary precautions were taken to prevent cross contamination (bag separated for laundering before reuse, hands and weighing pot cleansed with antiseptic gel).
