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.

DOWNLOAD EBOOK →The Texas Landscape Project explores conservation and ecology in Texas by presenting a highly visual and deeply researched view of the widespread changes that have affected the state as its population and economy have boomed and as Texans have worked ever harder to safeguard its bountiful but limited natural resources. Covering the entire state, from Pineywoods bottomlands and Panhandle playas to Hill Country springs and Big Bend canyons, the project examines a host of familiar and not so familiar environmental issues. A companion volume to The Texas Legacy Project, this book tracks specific environmental changes that have occurred in Texas using more than 300 color maps, expertly crafted by cartographer Jonathan Ogren, and over 100 photographs that coalesce to fashion a broad portrait of the modern Texas landscape. The rich data, compiled by author David Todd, are presented in clearly written yet marvelously detailed text that gives historical context and contemporary statistics for environmental trends connected to the land, water, air, energy, and built world of the second-largest and second-most populated state in the nation. An engaging read for any environmentalist or conscientious citizen, The Texas Landscape Project provides a true sense of the grand scope of the Lone Star State and the high stakes of protecting it.
