The BTO winter atlas showed that Woodpigeons were present in the majority of 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 246 birds seen in a day.

The BTO winter atlas showed that Willow Tits were present in the majority of 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 6 birds seen in a day.
The plotted winter distribution was slightly less widespread than that of the breeding season possibly due to a difference in observer effort, as this species is considered to be sedentary.

The BTO winter atlas showed that Woodcocks were present in the majority of 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 seen in a day.
Not easy to locate so it is likely this species was under recorded.

The BTO winter atlas showed that Wigeon were present in the majority of 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 300 birds seen in a day.
Over 2,000 within the Cleddau Estuary system constituted the main concentration.

One Whimbrel was recorded in Pembrokeshire for the BTO winter atlas during the winters of 1981-82, 1982-82 and 1983-84.
Very few Whimbrels are known to winter in Europe.

The BTO winter atlas showed that Velvet Scoters were present in two coastal 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 3-10 birds seen in a day.
They were mostly seen in association with Common Scoters.

The BTO winter atlas showed that Water rails were present in the majority of 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 seen in a day.
To a large degree the plotted distribution follows the degree of observer effort.
