I don't know what the national situation is but locally in Preston it seems to have been a very good summer for Goldfinchs, and I have discovered the killer food to attract them to your garden, I previously relied on nijer seed and had a lot of Goldfinchs visit regularly but I bought some Sunflower Kernals and within days I was getting 20/30 Goldfinchs at anyone time fighting to get on the feeder and bird table, with lots of this years youngsters amongst them. The photos below were taken this week, the left hand feeder has the sunflower kernals in and at the moment I fill it each morning and by mid afternoon its just about empty, with lots of Dunnock picking up the spills off the floor below. The photo quality is not great as the photos were taken through the conservatory window!
As you can see they are very competitive and constantly scrapping to get a peg on the feeder.
