Southern Guillemot - 1949

Iria aalge albionis

Mathew says it nested on all islands and various mainland cliffs, especially the Stack Rocks, which are today a "tourist" attraction in south Pembs - charabancs run regularly from Tenby during July, and park within a stonethrow of these striking pinnacles of detached rock, and the Guillemots and Kittiwakes seem little disturbed by human sightseers.  Breeds from Cemmaes Head to Caldey on suitable cliffs and stacks.  Decreased during the war.  Approximately 0.5% of the Guillemots on Skokholm and Somer were eximated in 1946 to be of the "bridled" form.
