Marsworth 16th July 2017 CES 8

Marsworth Reservoir CES 8
Weather: Cloudy, breezy
Ringers: LL, CK, GK, CMS
Nets up:  540'  05:15 to 11:15am

This is a bit of a delayed report on CES 8.
We had a slow start with only 20 birds by 7am but then it continued steadily with a good range of species. The long-tailed tits were all in wing moult and a few of the other juveniles had started post-juv moult: great tit, willow warbler, reed bunting, goldcrest (see photo below) and one or two blackcaps and chiffs.
The final total of 85 was above the average (76) and our yearly total is now 480 compared to an average of 453. This is a result of the last two good sessions.

Goldcrest with adult feathers growing on head

Reed warbler with fault bar on tail - a result of poor nutrition when the feathers were growing.
