New bird I've never seen before...Redpolls

When I started my watch I saw a bird that I didn't know, but it was a fleeting glimpse. It had a red line on the top of it's head. Luckily it came back and this time brought a male companion and decided to sit in the top of the Hawthorne bush quietly. I went through my garden bird book looking for it, as one had a very clear red head. And there they were: 2 redpolls, 1 male, 1 female, sitting with goldfinches.
