Only really got it going full on this year, so still getting more visitors as the year goes by. Got fat ball feeder, mixed seed, sunflower seeds, niger & peanuts. And a homemade watering station made out of some old canes and a plastic plant water dish (the thing that sits under the plant pot!).

A shower of sparrows - tinkers the lot 'em, but sit and chatter beautifully, bicker maniacally. Usually a minimum of 20 hanging around!
*(had a nesting pair in spring in our huge clematis, but the female was very young, I think, and never came back one day - the male spent the next month singing his little heart out from out TV aerial..). Also, was woken up one Sunday whilst she was still around, by her alarm call, to find a flock of magpies raiding the nest - scared them off, and put up some meshing around - she was well happy for a short while
