Blue Tits have been common since Mathew’s (1894) time. They breed in a variety of habitats, including urban areas where they utilise holes in masonry and nest-boxes, and are only absent from the tops of the Preseli Mountains and all of the offshore islands save well-wooded Caldey. Census data from the Dyfed Wildlife Trust reserves of Rosemoor, Old Mill Grounds and Pengelli Forest, suggest an average of 60 pairs per tetrad which would amount to a county total of about 24,000 pairs.

They are eruptive in some autumns, like Coal Tits, and flocks are seen wandering q about the open coast, some reaching the offshore islands, with up to 50 at Skokholm in October 1957 and 1964 and 85 at Skomer in October 1991.
