Pembrokeshire Avifauna committee in 1980s BTO winter atlas, Black Redstart, GHR

The BTO winter atlas shows the 10km squares where Black Redstarts were recorded 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 3 birds seen in a day.

Mainly recorded around buildings.
