Kestrel - 1980s winter atlas
Sunday, October 9, 2011 at 5:03PM
The BTO winter atlas showed that Kestrels 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 3-4 birds.
