Excerpt

This bulletin contains a continuation of the work on the life histories of North American birds, begun in Bulletin 107 and continued in Bulletins 113 and 121. The same general plan has been followed and the same sources of information have been utilized.

Nearly all those who contributed material for former volumes have rendered similiar service in this case. In addition to those whose contributions have been previously acknowledged, our thanks are due to the following new contributors:

Photographs have been contributed by A. A. Allen, J. H. Bowles, A. D. Dubois, J. Labarthe, C. W. Townsend, and W. Raine.

Notes and data have been contributed by A. A. Allen, G. M. Allen, H. W. Brandt, L. Griscom, J. F. Honecker, W. J. Hoxie, J. C. Phillips, and G. M. Sutton. Mr. Wharton Huber has written the life history and the distribution of his new species, the New Mexican duck.

Dr. John C. Phillips has furnished the references for the life history of the falcated teal and very kindly placed at the author's disposal his entire unpublished manuscript on this species.

The information previously furnished by Dr. T. S. Palmer, on bird reservations belonging to the United States, and a lot of data recently furnished by Mr. Hoyes Lloyd, on Canadian bird reservations and sanctuaries, form such a voluminous mass that it seems best to leave it for future publication by itself, rather than attempt to do but scant justice to it in this bulletin.

The distributional part of this bulletin is the work of the author; but it has been examined by Mr. James H. Fleming, Mr. P. A. Taverner, and Mr. F. Seymour Hersey. Mr. Hersey also figured the egg measurements, after collecting a lot of additional measurements from some of the large egg collections, notably those of the California Academy of Sciences (Mailliard collection), the Colorado Museum of Natural History (Bradbury collection), Mr. Richard C. Harlow, Col. John E. Thayer, and the University of California (Grinnell collection).

In outlining the breeding ranges of the ducks, no attempt has been made to mention all of the many cases recorded of northern breeding species which have lingered for the summer and bred far south of their normal breeding ranges, as such birds are often cripples; only a few cases have been mentioned which seemed to be casual breeding records of normal birds.
