The BTO winter atlas showed that Rooks 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 800 birds seen in a day.

Use of treeless coastal areas resulted in a winter distribution that was slightly more extensive than the breeding range.

Rock Pipit - 1980s winter atlas

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.

Robin - 1980s winter atlas

The BTO winter atlas showed that Robins 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 36 birds.

However, it should be noted that the figures show a high correlation with the number of recording cards returned (therefore related to recording effort) for each 10km square.
