So I returned today when the sun shone, and this time managed a few pictures. They were all so skittish though. Anything closer than 30 yards and they were off. So I turned to stealth mode. This meant I was stood close to, but not in, a hedge for quite some time, not moving. I was happy with the Fieldfare shots I got. Could have had a few less branches in front of it, but it's better than nothing.
Redwings were not so accommodating, and very flighty. This was taken at quite some distance.
