I have a feeding pole not quite in the middle of the garden and there are usually at least half a dozen goldfinches always buziing around it - they are quite bullish about who gets to the seeds first - it's them! Everyone else gets a turn after they've had their share! I've found that sunflower seed hearts go down really well, but they do like the nyjer seeds just as much (as does our resident wood pigeon, Chris, as my daughter named him) Recently, I've also had a pair of siskins and a bullfinch at the sunflower seeds.
