Pembrokeshire Avifauna committee in 1980s BTO winter atlas, Collared Dove, GHR

 

The BTO winter atlas showed that Collared Doves 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 50 birds in a day, reflecting winter flocking.
