European storm petrel

Short abstract from the book:
The European storm petrel is the most numerously ringed bird species in the Faroes with 37,530 ringed birds. The majority has been ringed on Nólsoy (26,100) where they are ringed either in or close to the large colony which is estimated to hold 150,000 pairs. During 1986-1989 a high number were ringed (11,439) in a regional cooperative ringing initiative under the coordination of Tony Martin, where Britain, Iceland and Norway also participated. European storm petrels have been ringed from 24 May to 21 November, most in August (24,040). 0.3% were ringed as chicks. 307 have been recovered, 80 of them from abroad. Only 0.8% have been recovered, most of them controlled during ringing activities, in the Faroes and abroad. All recoveries are of birds ringed between 6 June and 26 October. Two recoveries of birds in Fair Isle, Shetland only four days after ringing in the Faroes, seem to suggest a wide dispersal in the NE Atlantic as does a bird ringed 10 August 1988 in Wick, Scotland and caught the day after on Nólsoy, 443 km NNE of the ringing site. Autumn migration is from late October to early December towards S. The wintering area of European storm petrels is off the coast of South Africa. Most have been controlled (95%). The main causes of death of recovered birds are killed by other bird (27%) or by cat (27%).
