Most of the chapters in this book appeared originally as articles in the Nineteenth Century during the years 1902-1904; and I wish to thank the editor, Sir James Knowles, for his kind permission to reprint them after a shorter interval than is usual. They have all been carefully revised, and have, in many places, been recast and received large additions. Of the other chapters, one, that upon "The Wild Duck," was published, many years ago, in Bailey s Magazine. The account of the Short-eared Owl appeared, as recently as August last, in the shape of a separate article in the Outlook, and it was followed up in October by a second article in the same paper, on the birds of Norfolk. To the editors both of Bailey s Magazine and the Outlook, I have to return my grateful acknowledgments for the leave which they have given me to reproduce them.
