New birdie in garden

A few days ago I replaced the “bird seed mixture” in this feeder with nothing but (unshelled) sunflower seeds. It didn’t take long for the goldfinches to spot their favourite food, even though I had never seen them in my garden before.
Well, they have to share with the tits. But their technique of “eating” is different: the tits come to look for a seed, then go to shell it quietly a little further on a branch of the apple tree. The goldfinches, for their part, peck and throw husks (and seeds) all around them. In one day the feeder is emptied.
