Studies in Bird Migration - With Maps, Weather Charts, and Other Illustrations #247509

A number of the stations visited had either never before been explored ornithologically, or only partially so, and as their bird-life is of considerable interest, a complete concise account of their feathered natives is afforded. During the many years devoted to this work I was the recipient of many acts of kindness, and have been laid under numerous obligations. For these, gratitude compels me to express my deep sense of the value of the services rendered and my high appreciation of them.
