Motacilla alba yarelli – SIGLEN FRAITH – Breeding resident and passage migrant
The BTO winter atlas showed that Pied Wagtails 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 19 birds seen in a day, or at roosts.
