Print on Demand. This book explores the hidden world of bird incubation periods. For the first time, the author has compiled a list of incubation periods for 625 species and subspecies, offering a wealth of data for ornithologists, biologists, and bird enthusiasts alike. The book examines various theories proposed to explain the factors governing the length of incubation, including the size of the bird, the age of the female, and the precocity of the young. The author also delves into the effects of external factors, such as temperature and nest site, on incubation duration. This book is a valuable resource for anyone interested in the fascinating process of bird reproduction. It provides a comprehensive understanding of the factors that influence incubation periods and sheds light on the evolutionary adaptations that have shaped this crucial stage in the life cycle of birds. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

In the course of certain studies in ornithology, more particularly avian physiology, undertaken by the author several years ago, it early became apparent that the factors fixing or determining the length of the incubation period with different birds was largely, if not wholly, unknown.
The following pages give the results of a prolonged and detailed study of this phase of bird physiology.
The author regards all zoologic classification as a means, not an end; the classification adopted in this work is merely a means of facilitating the handling of a mass of data full of contradictions and uncertainties, and the selection of this particular bird classification was governed by a question of expediency only; obviously the author in no way wishes to be understood as believing this classification to be the best, or the only one. The author believes, however, that this classification is an up-to-date reflection of our present knowledge of the relation of vario'us birds to each other.
It is inevitable that mistakes of various sorts will be found in this book; in extenuation of such errors the author trusts that his critics will recall that the labor involved in the investigations reviewed in the following pages was one of love, and carried on in the spare moments of a fairly busy professional life.
A brief resumé of pages 43 to 76 of this book was read before the Annual Meeting of the American Ornithologists' Union at Philadelphia, November 15, 1916.
