Chaffinch – 1980s winter

Fringilla coelebs – JI-BINC – Breeding resident and passage migrant

The BTO winter atlas showed that chaffinches were present in virtually all 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 360 birds, with the highest count being 1258 in SM80.

However, it should be noted that the figures show a high correlation with the number of recording cards returned (therefore related to recording effort) for each 10km square.
