From Foreward: Lovers of the great out-of-doors, as well as those scientifically inclined, are to be felicitated upon the publication of The Birds of Oregon by Gabrielson and Jewett. For forty years these men patiently and painstakingly assembled the material for this imposing and delightful book. They brought to the task a wealth of experience and of scientific knowledge. They covered the state from the Columbia to Goose Lake and from the Pacific Ocean to the Snake River. By personal contact they know Oregon from sea level to the summit of Mt. Hood. They transferred from nature's book to the printed page some of nature's most interesting and beautiful expressions.
