What these next to goldfinchs

I would say they are probably either siskin or redpoll - did you notice any red on the top of their heads?
If so they are most likely redpoll - if not they are probably siskin, though I could easily be wrong.

It was hard to see if they have any red, don't think they siskin from the pictures I've looked at, maybe female redpoll I think

Redpolls.
