Pembrokeshire Avifauna committee in 1980s BTO winter atlas, Chough, GHR, corvid

The BTO winter atlas showed that Choughs were recorded in most coastal 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darkest blue on the map represents over 5-11 birds seen in a day, meaning immature birds were recorded as well as territory holding adults.
