With a bit of perseverance, at long last I have now managed to get Goldfinches into the garden continually; I have put out a lot of Sunflower hearts for them, and this is really doing the trick to attract them.

As well as Goldfinches, Blue Tits, Sparrows, and long tailed Tits are also enjoying all the food.

For me, a little but very worthwhile victory.
