Today we had a successful second CES (Constant Effort Site) ringing session at Thornwick. When we arrived the weather conditions were ideal with an overcast sky and no wind which make the nets less visible to birds. We got our 9 standard nets up in a quick 30 minutes so had time for a quick tea and biscuit break. It was a steady session with a larger than average number of whitethroats (6) and lesser whitethroats (3) caught.
There were a nice variety of birds with 14 species caught in total (26 newly ringed and 9 retraps).
We are looking forward to finding out valuable trend information on abundance of adults and juveniles, productivity and also adult survival rates through this national scheme.
