Sculthorpe Moor - 22nd August 2022

 We got a session in today, in advance of some windy, and potentially wet weather, followed by a return to temperatures in the high 20s. It was the first time we'd ringed here on a southerly wind and that may have contributed to the distinct feeling that many summering warblers had pushed southwards on autumn migration. Migrants like flying into a headwind. It's beneficial for generating lift when there are substantial distances to cover and Norfolk birds tend to head to the south coast rather than heading east.

We processed a total of 40 birds although half being Blue Tit was rather too many for our liking. These birds do not tend to travel much in the UK and numerous studies can attest to their survival rates and factors influencing breeding productivity. However, continued monitoring for change in circumstances is still important. Six Chiffchaff and two Sedge Warblers were the only summer migrants captured.

There was a nice spread of resident species including adult birds, some of which are now nearing the end of their main moults following the breeding season.
