The BTO winter atlas showed that Little Grebes were present in about 56% of Pembrokeshire 10km squares during the winters of 1981-82, 1982-82 and 1983-84, being found on both fresh and estuarine waters.
The darker the colour, the higher the relative total count for each 10km square. The darkest blue represents over 9 birds, 25 being the Pembrokeshire maximum.
