Birds are hosts to many parasites, internal and external. The parasites inevitably form a burden to the host bird and therefore may affect its ability to grow, survive and reproduce as well as its behavior and the abundance and distribution of the whole species. As a consequence, bird-parasite systems have attracted attention from diverse fields. This book draws together a comprehensive range of experts in the field to provide an invaluable reference of current work in bird-parasite interactions. The book addresses the contemporary context of research in bird-parasite systems, and case...

Scientific discoveries about the animal kingdom fuel ideological battles on many fronts, especially battles about sex and gender. We now know that male marmosets help take care of their offspring.
