For the past 2 or 3 days we have had a flock of fieldfares and redwings come to visit mostly next door's holly tree, but also our smaller one. They prefer next door's as it has a lot more berries, being a bigger tree, it also gives them more cover, and it's further from the road. I have taken some reasonable photos of them. I don't think they will be back much more though as there are so few berries left. Also, the snow is melting now and presumably they will be able to find enough food without the risk of visiting built-up areas.
Yesterday I counted 14 fly away from the trees when they had finished guzzling. Today I didn't manage to count them as there were too many - certainly in excess of 20.
