These are female Purple Finch hanging out with their male friends. Don't like the snow in the background, yuck!
thanks - Pam
I agree with Gordon that the bird in question looks like a female Purple Finch but it also could be a young male. Purple Finch are birds that take 2 years for the young to mature to adult plumage. During this time the males resemble females. An immature male could show a bit of yellow/orange.
