The BTO winter atlas showed that Merlins 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 2 birds seen in a day. The map plot clearly indicates this species ability to utilise all kinds of open habitat.
