The BTO winter atlas showed the 10km squares where Long-eared Owls 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 2 birds seen in a day, the lighter blue represents single birds.

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.

The BTO winter atlas showed that Kingfishers were present in about 40% of Pembrokeshire 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 3 birds.

The BTO winter atlas showed that Jays 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 11 birds.
It is possible that the highest numerical plots were due to a hangover from the Jay invasion of autumn 1983.

The BTO winter atlas showed that Grey Wagtails 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 4 birds.
The map plot shows a slightly wider winter distribution than that of the breeding season.

The BTO winter atlas showed that Greenshanks were present in six estuarine 10km squares during the winters of 1981-82, 1982-82 and 1983-84.
The darkest colour represents over 6 birds seen a day. It is likely that the birds concerned were Scottish breeders.
