Phalococorax carbo – MULFRAN – Breeding resident
The BTO winter atlas showed that Cormorants were present in most coastal and estuarine 10km squares and on some inland waters 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 25 birds.
