We had a productive ringing session for autumn migrants last weekend, processing 97 birds (5 recaptures and 92 newly ringed). Most notably, we ringed 41 Chiffchaffs, which are passing through South in decent numbers at this time of year.
We also ringed 4 Goldcrests (a.k.a. Europe's smallest bird!). They were all young birds that had fledged this year, 3 males and 1 female. These were most likely local birds, however some Scandinavian Goldcrests do migrate to the UK to overwinter here.

The recaptures included a young female Green Woodpecker, which had been ringed at the end of July. This individual could now be sexed as female due to there being no trace of red in its black submoustachial stripe.
