Blackcap – 1980s winter

Sylvia atricapilla – TELOR PENDDU – Breeding summer visitor, passage migrant and winter visitor

The BTO winter atlas showed that Blackcaps were present in almost 40% 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 recorded per day.

Blackcaps visiting bird feeders has aided detection.
