Excerpt from Economic Status of the English Sparrow in the United States Since 1889, however, many changes have taken place. The range Of the English sparrow in this country has more than doubled, and the bird has come to be Of economic importance in every State. Changed agricultural practices, extension Of crop areas, phenomenal growth Of metropolitan sections, successive inroads Of various new insect pests upon which the bird can prey - these and many other factors have added much to the history Of this imported bird, and In the light Of these altered conditions there has grown a need for another appraisal Of its economic worth. TO supply this has been the Object Of the present investigation. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

After the chicken, the House Sparrow is the most widely distributed bird species in the world, occurring on all continents except Antarctica and on most human-inhabited islands. Although its Latin name is Passer domesticus, it is certainly not domesticated. In fact, it is widely regarded as a pest species and is consequently not protected in most of its extensive range. This combination of ubiquity and minimal legal protection has contributed to its wide use in studies by avian biologists throughout the world.The purpose of this book is to review and summarize the results of these global studies on House Sparrows, and to provide a springboard for future studies on the species. House Sparrows have been used to study natural selection in introduced species, circadian rhythms, and the neuroendocrine control of the avian annual cycle. One current question of considerable interest concerns the catastrophic House Sparrow population declines in several urban centers in Europe. Is the House Sparrow a contemporary canary in the mine? Other topics of broad interest include the reproductive and flock-foraging strategies of sparrows, and sexual selection and the function of the male badge in the species. Anderson also explores the role of the House Sparrow in disease transmission to humans and their domesticated animals.

While Denis Summers-Smith's monograph The Sparrows presented his knowledge of sparrow biology, this volume tells the other, human, side of the tale. Denis Summers-Smith first took up the study of the House Sparrow in 1947, thinking that the difficulties of travel in post-war Britain would best suit the study of a species always close at hand. The humble House Sparrow, common everywhere, was surprisingly poorly researched and his work soon provided interesting insights into this successful and adaptable little bird. As new opportunities to travel opened up, his interest blossomed to take in the genus Passer as a whole. His travels would ultimately lead to his study of all but one of the group, found only in deepest Turkestan, and to the publication of his authoritative monograph on sparrows in 1988. His wry descriptions of the tribulations and unexpected pleasures of a traveller on four continents, from the Himalayas and Thailand to Africa and the Americas (with a good few islands in between), are interspersed with observations and speculations on the biology of sparrows in a wide variety of habitats. Everywhere local officials and bird watchers warmed to the eccentric Scot in pursuit of the little birds that nobody notices but which so often make their homes beside us. The author's own photographs and delightful cartoons by Euan Dunn further paint the picture of this lifelong search.

Examining globally invasive alien birds, the first part of this book provides an account of 32 global avian invasive species (as listed by the Invasive Species Specialist Group, ISSG). It acts as a one stop reference volume; it assesses current invasive status for each bird species, including details of physical description, diet, introduction and invasion pathways, breeding behaviour, natural habitat. It also looks at the environmental impact of each species, as well as current and future control methods. Full colour photographs assist with species identification and global distribution maps give a visual representation of the current known distributions of these species. The second part of the book discusses the biogeographical aspects of avian invasions, highlighting current and emerging invasive species across different regions of the world. The third section considers the impact of invasive species on native communities, problems associated with invasive bird management and the use of citizen science in the study of invasive birds.
