Short ringing session

Heysham Obs
The feeder nets were set for a short time as the snow melted before our eyes.  Average weights were about 2-4 grams more than usual and the catch saw several retrap tit species & a local Robin, but all the rest of the birds were unringed: single Brambling, 5 Greenfinch, 2 Chaffinch & a Dunnock.  Despite rapidly improving conditions, the nets were taken down after 1.5hrs to allow plenty of time for any birds which might have been put off visiting the feeders to feed.  In this respect, there were plenty of net-familiarised tits feeding & avoiding capture and all the small number of finches appeared to be unringed birds, as has been the pattern all autumn.
