The purpose of this book is to explain why red-winged blackbirds are polygynous and to describe the effects of this mating system on other aspects of the biology of the species. Polygyny is a mating system in which individual males form long-term mating relationships with more than one female at a time. The authors show that females choose to mate polygynously because there is little cost to sharing male parental care in this species, and because females gain protection against nest predation by nesting near other females. Polygyny has the effect of intensifying sexual selection on males by increasing the variance in mating success among males. For females, polygyny means that they will often share a male's territory with other females during the breeding season and will thus be forced to adapt to frequent female-female interactions.
This work reviews the results of many studies by other researchers, as well as presenting the authors' own results. Studies of red-winged blackbirds have ranged from long-term investigations of reproductive success and demography, to research on genetic parentage based on modern molecular methods, to a variety of experimental manipulations of ecological circumstances and behavior. Since the red-winged blackbird is one of the best studied species of any taxa in terms of its behavior and ecology, the authors have a particularly extensive body of results on which to base their conclusions.

October, 1901. Lawyer and private enquiries agent Karl Werthen accepts an assignment to protect the famous Irish writer Bram Stoker while on a speaking tour of Vienna. Meanwhile, his colleague, renowned criminologist Dr Hanns Gross has been called away to advise on a bizarre series of murders near his hometown of Graz, in the Austrian province of Styria. Three women have been killed with strange mutilations and scarring patterns left on their bodies. The third, most recent victim has had her unborn baby cut out of her womb. Clues have been left at each scene; clues that have been clearly mentioned in Gross' handbook for magistrates, Criminal Investigation. A coincidence? Dr Gross thinks not. Meanwhile, back in Vienna, Werthen's wife Berthe is investigating what seems to be a fraudulent breeding scheme involving the prized Lipizzaner horses. Could the two investigations possibly be connected? Matters become complicated with Werthen and Stoker's arrival in Graz. For, having read wild newspaper accounts of vampire killings, the Dracula author insists they investigate.
