I use sunflower hearts which attract sparrows, robins, greenfinch, tits, goldfinch and tree creeper, with dunnocks cleaning up anything spilt on the patio. I buy them from eBay branded as Croston Corn Mill Ltd £24.95 for 20kg sack. These are the best I've found, others often have a powdery residue that clogs up the feeders. I used to buy RSPB sunflower hearts from a local RSPB bird sanctuary, but they are expensive.
