Craig yr Aderyn (Bird's Rock)

image: SPA location map 


The high crag of Craig Yr Aderyn / Bird's Rock in west Wales, rising from sea level to over 250 m, is a striking landscape feature on the south side of the Dysynni valley near Tywyn. The SPA comprises rocky crags, acid grassland, heath and Bracken Pteridium aquilinum. The site is of European importance as a traditional breeding and roosting site for Chough Pyrrhocorax pyrrhocorax, which are present throughout the year. Non-breeding birds roost during the summer and traditionally there are high numbers outside the breeding season. The maintenance of a short grassy sward, which provides an important feeding area for Chough, is considered one of the factors influencing the number of breeding and roosting birds.
