Earlier in the year we noticed that our neighbour had goldfinches on her feeder and we didn't so we asked her what to feed them. Anyway we set up 3 hanging feeders on a feeder station and were delighted to see goldfinches appear. We put niger seed and sunflower hearts in the feeders. I was particularly pleased last week to see four adults and two juveniles all together, but yesterday evening at around 5.30pm I counted ten adult goldfinches all together at the three feeders. There was a bit of squabbling going on, but it was a great sight. Do goldfinches tend to flock together at certain times of the year?
