The BTO winter atlas showed that Bullfinches were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84.
The darker the colour, the higher the relative total count for each 10km square. The darkest blue represents over 15 birds recorded in a day. The largest gatherings were due to birds from the surrounding neighbourhood gathering at good local food sources.
