-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..

Club George is a witty tale about one man+s adventures with George, a particularly charismatic Red-winged Blackbird. Wryly humorous and brimming with affection for birds in general and George in particular, this book combines solid natural science with stylish prose and endearing photographs. The cast of characters includes creatures of all kinds, both human and not, and supporting roles are played by Pale Male and Lola, the famous Red-tailed Hawks whose nest was unceremoniously removed last year from their fancy Fifth Avenue building to a worldwide furor of protest. Both useful and entertaining, Club George covers everything from how to buy binoculars to fascinating trivia about New York+s most famous park. This amusing gem will be welcomed by book-buying birdwatchers, Central Park enthusiasts, and armchair nature lovers everywhere.

Description:
In the first attempt to re-establish a population of the red-winged grasshopper, Oedipoda germanica (Latr.), threatened with extinction in Germany, 32 adults (19 females, 13 males) were taken from a population in a limestone quarry, individually marked, and translocated to the ''Leutratal'' nature reserve near Jena, Thuringia, formerly inhabited by the species. A simulation model with two scenarios was run to determine the probability of re-establishment of this small translocated population. One of the two scenarios indicated that populations of 20 females could survive with optimal life history parameters. In 1994, the year of translocation, during seven nights of observation between July and September, 25 adults were re-observed at least once. About 50% of the females and 70% of the males were found in a 20m radius of the release point, whereas a maximum distance of about 70m was recorded for a female. Using minimum female life-span and oviposition data from greenhouse experiments, 545 eggs were estimated to have been laid by the initial inoculum in 1994. In the subsequent years 1995 and 1996, only seven and three grasshoppers were observed within 30m of the release point in 1994. However, the translocated population obviously went extinct in 1997 because no O. germanica could be found in that or following years. By comparing source and release habitat, the possible causes of the failed re-establishment were elucidated. In the year of release a short mean adult life span of 26 days was observed, assumed to be the consequence of high predation, and resulting in a lower reproductive rate. In the following years, low soil temperature of the release habitat probably delayed egg hatching for about 1 week, delaying phenology and thereby reducing the period over which eggs could be laid. A rapid population decline resulted in only three females found in the year before extinction. .
