Well, the fieldfares are so busy fighting each other and the blackbirds
that none of them seem to have time to eat.

I've increased the number of feeding stations to try and split them up,
but there are still too may birds to feed peacefully.

Earlier there were just loads of blackbirds - seven or eight males -
all sitting on the fence or surrounding trees.
For terrritorial birds this is most unusual.

A lot of the ones around at the moment are migrants, so would they be
acting territorially if they're not planning to breed here?

Things must be getting pretty desperate in the avian world now that the
normal food sources are covered in snow and ice.

Also lack of water is a problem. ot just for drinking but also for
keeping feathers clean and fluffy to keep out the cold.
