Garden BirdWatch data shows how they peak in winter but it does vary from year to year depending on how mild the temperatures are and the availability of food in the wider countryside.

Distribution
least likely to be observed
Recent work discovered that these birds have changed their migration pattern, in part, thanks to the provision of garden bird food. They will mostly go to urban and suburban gardens (heat island effect), and to those in the south west, but only if they regularly provide food.
