Snow and hoards of hungry birds

Yes, more, and more. A couple of feet so far and now it's freezing solid.
The bird feeding stations have been doing a roaring trade (must order more food...!). Yesterday there were four robins, carefully watching each other and taking turns; today there were three.
We've also seen a redwing in the holly tree on a couple of occasions. When the finches numbered over fifty we stopped counting but all three main groups have been here in great numbers along with lots of bramblings. One bird which is missing is the siskin, we have seen only one or two.
