Harriers of the World

Bok av Robert Simmons
Harriers are a world-wide group of birds of prey whose mating systems, population dynamics, and evolution are well-studied. This is the first book to synthesise and analyse the masses of data on the behavioural ecology of harriers. It offers an intriguing comparison of breeding systems among harriers in the northern and southern hemispheres, and includes a new phylogeny of the harriers, based on the most recent DNA findings. It is illustrated throughout with original line drawings of these impressive birds.
