We had never had any success with attracting Goldfinch to the garden feeders but recently we have had them on the telephone wires just outside the front door.
So we obtained some Nyger seed and appropriate feeder and after a couple of blank days in the back garden I transferred it to the front.
Two days ago we had a Greenfinch investigating the feeder but today bingo!
a couple of Goldfinch visited on an hourly basis.
So managed a few pics through the window.
Next step is to try to tempt them into the back garden where I stand a bit of a chance of obtaining photos without using the windows
