The BTO winter atlas showed that Song Thrushes 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 26 birds seen in a day.

There was a marked increase in Pembrokeshire during the cold weather of 1981-82.
