Ducks The fifth edition of this tried and tested manual takes into account many new discoveries about sophisticated methods of behaviour, breeding and hygiene, but also about incubation technology, ways of behaving and cycles of moulting. Up to date details on outdoor conditions, causes of decline and protection regulations inform you about the distribution and status of individual types. Further, the morphology, distribution, biology as well as behaviour and breeding from 67 species and subspecies of the families swans, geese, and ducks is described. The outstanding colour photos spare the long descriptions on plumage. Some species are portrayed for the first time. HARTMUT KOLBE works as a biologist with a degree in the breeding and behaviour of ducks.
