Résumé :	Detailed records of 108 Common Buzzard Buteo buteo nests were kept during 1997-2004 as part of a long-term study of the species in Avon. Various aspects of the nest were measured, including size and supporting structure, height above ground, and height and species of tree. Nests varied in size from 1,244 to 4,196 cm(2). Larger broods were in the biggest nests, and were also significantly earlier than smaller broods. Nest and tree heights matched those in other studies in Britain. Seventeen tree species were used, with Oak Quercus robur the most frequent. Ivy Hedera helix was an important component in nest structure but nests with Ivy were less successful than those without. Food remains at nests showed a wide variety of prey, similar to that of other British studies. The commonest mammal was the Rabbit Oryctolagus cuniculus (71%) and the commonest bird species was the Wood Pigeon Columba palumbus (27%).
