Excerpt from Birds of the Colorado Valley: A Repository of Scientific and Popular Information Concerning North American OrnithologyA portion of the Colorado Valley, in Southwestern Arizona and adjoining parts of California, has long been known as the hottest place in the United States. At Fort Yuma, on the Colorado River at the mouth of the Gila, in latitude 320 longitude 1140 36' the mean annual rainfall does not exceed five inches. A temperature of 1190 F. Has been recorded and for weeks in succession the mercury may rise above 1000 daily. For several hundred miles the great river rises but little, its elevation at Fort Mojave, for instance, being only about 525 feet. South ern and Western Arizona is a torrid, alkaline waste in fact, a part of the Great American Desert, yet in the central portion of the Territory rise the magnificent San Francisco Mountains, feet high, pine-clad, and snow-capped during a portion of the year, and at Fort Whipple, with an altitude of feet, the general course of the seasons is not materially different from that in the Middle Atlantic States. A day's jour ney from the last-mentioned locality will show differences in the bird-fauna comparable, for instance, to those distinguish ing Massachusetts from the District of Columbia. Many of the birds of Fort Yuma and Fort Whipple respectively are total strangers to each other.Such striking features as are here brie¿y indicated render the study of the birds of this region specially attractive, and exact information respecting their distribution and movements within the area in question is very desirable. The whole subject is elucidated in detail in the present treatise.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
