Mousa Brock Storm Petrels a short essay by Hugh Harrop.
This striking Iron-Age stone fort (brock) in the Shetland Islands holds a colony of several thousand European Storm-Petrels.

Ponta da Alamadena, Algarve, Portugal: storm-petrel study site
Long-term ringing study of migrants by the A Rocha Bird Observatory in collaboration with Cardiff University. The number of recaptures from distant colonies (NW Spain, Scotland, Iceland) is very interesting. Approximately 8% of the European Storm-Petrels trapped at this site are already bearing a ring, or are later recaptured in north-west Europe. The results demonstrate the rapid movements of storm-petrels around this corner of the Atlantic. Many appear to be non-breeders apparently checking out potential nest burrows and mates for the future. Older, breeding birds, are apparently less attracted to tape lures.
