The e-book is split into 4 major sections: the 1st is introductory, describing the differing kinds of chook pursuits, equipment of research, and the most migration styles visible round the British Isles; the second one half is anxious regularly with the method of migration – with timing, power wishes, climate results and navigation; the 3rd with evolution and alter in migratory behaviour; and the fourth with the geographical and ecological facets of fowl movements.
