Same here - it's great to help isn't it. All summer we have mobs of tree and house sparrows at the feeders, now it's mainly tits - great, blue and coal - robbins, blackbirds, the odd goldfinch, greenfinch, woodpeckers and some sparrows, but they come in a bunch then go somewhere else, probably still mopping up the grain left from the rotting cereal crops. On the ground we have dunnocks, chaffinches, robin and suchlike.
We got them a mealworm feeder which we put up yesterday, but they are still a bit nervous of it - I'm sure that won't last long.
Feeding the wild birds really does help them to get through deep cold like we are having, then in spring it gives them some extra energy for producing and rearing young.
