This paper reports the findings of a long-term study of the Honey-buzzard Pernis apivorus in Britain during the breeding season. It is based upon data from 406 nesting attempts in 73 different nesting areas, between 1972 and 2012. Since a paper in British Birds in 1999, which reported on the early years of this study, the introduction of a colour-ringing project, satellite tagging and more in-depth dietary analysis has helped to broaden the scope of the project, allowing investigation of dispersal and population dynamics as well as all aspects of breeding biology. The Honey-buzzard remains a rare breeding bird in Britain, although the national population is now thought to be in the region of 100-150 pairs. A greater understanding of the species' habits and behaviour during the breeding season is a critical step towards effective conservation of one of Britain's rarest and least-known breeding raptors.
