Wren – 1990s winter

Troglodytes troglodytes – DRYW – Breeding resident

The BTO winter atlas showed that Wrens were present in the majority of 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 25 birds seen in a day
