At this time of year Redpolls are a species to look out for.
You may not see one all Winter or you could be lucky and just come across them one day, just like I did with these.
There was only a small flock and they (as many other species do at this time) were not wasting time and feeding away ferociously. The seeds of the dead Rosebay Willowherb is a great source of food for the Redpoll and quite a favourite of Goldfinch as well.
Having classed these as Lesser Redpolls, the first one below has some markings like a Mealy Redpoll on its back although its not really white enough, so its probably a Lesser.
I get confused with Redpolls, amongst many others I hear you say, well its a Redpoll, I just take the photographs :)
