Rock Pipit - 1980s winter atlas
Sunday, October 9, 2011 at 8:37PM
The BTO winter atlas showed that Rock Pipits were present in most coastal and estuarine 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 16 birds.
