This morning Craig went to Öby Kulle, whilst the rest of us went to Banvallen. Craig caught a total of 27 birds including 7 retraps. Highlights came in the form of 3 Tree Pipit and a Spotted Flycatcher
Totals for Öby Kulle: (Retraps in brackets)

Highlights from the 33 (1 recap) birds we caught at Banvallen came in the form of a juvenile female Redstart which had almost completed it's post juvenile moult so looked very smart indeed. After worrying that I wasn't going to see many more Thrush Nightingales whilst in Sweden, I was very happy to catch 4 today, including a 2cy+ bird that was ringed in June. It was nice to be able to compare the ageing criteria of a freshly moulted adult and a juvenile which is very close to completing post-juvenile moult. The adult was carrying a lot and was 'Fat 7' on the scale of 0-9, so I think we were very lucky to retrap this before it migrates away from Kvismaren.
