During this Winter until now I don't recall observing more than the odd single Redwing.
This species visits the UK during that period from Scandinavia and the Taiga Forests of Northern Europe. Our recent Winters have remained mild in comparison and this and the similar Fieldfare species just don't travel quite so far South.
This last week I was walking an area of the local Parkland, when I could hear the familiar noise of Redwing flying in the trees over my position. Fortunately, one of twenty plus landed in a tree near me and I was able to get a few shots.
