A pine siskin and red-breasted nuthatch

This morning the ground is covered with a thin layer of snow. A large flock of house sparrows invaded the feeder and managed to toss some of the seeds on the snow where it is picked up by many of the sparrows.
Yesterday I saw a long red-breasted nuthatch visiting the feeder. A flock of sparrows also appeared and along with them was a lone pine siskin. The sparrows are somewhat larger than the poor siskin. The siskin did not seem to be attacked even though it was certainly a minority of one in the large flock. Of course it was crowded when it decided it had a claim on the feeder space not just the space on the ground where there was a lot of fallen seed.
