Introduction ix

Order PASSERIFORMES 1

Family Parulidae: Wood warblers 1

INTRODUCTION

This is the nineteenth in a series of bulletins of the United States National Museum on the life histories of North American birds. Previous numbers have been issued as follows:

The paragraphs on distribution for the Colima and Kirtland's warblers were supplied by Dr. Josselyn Van Tyne with his contributions on these species.

All other data on distribution and migration were contributed by the Fish and Wildlife Service under the supervision of Frederick C. Lincoln.

The same general plan has been followed as explained in previous bulletins, and the same sources of information have been used. It does not seem necessary to explain the plan again here. The nomenclature of the Check-List of North American Birds , with its supplements, of the American Ornithologists' Union, has been followed. Forms not recognized in this list have not been included.

As the demand for these Bulletins is much greater than the supply, the names of those who have not contributed to the work during recent years will be dropped from the author's mailing list.

Dr. Winsor M. Tyler has again read and indexed for this volume a large part of the current literature on North American birds and has contributed four complete life histories. Dr. Alfred O. Gross has written stories on the yellow-throats and has contributed three other complete life histories. Edward von S. Dingle, Alexander Sprunt, Jr., and Dr. Josselyn Van Tyne have contributed two complete life histories each.

INTRODUCTION

William George F. Harris has increased his valuable contribution to the work by producing the entire paragraphs on eggs, including descriptions of the eggs in their exact colors, assembling and averaging the measurements, and collecting and arranging the egg dates, as they appear under Distribution; the preparation of this last item alone required the handling of over 5,600 records.
