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 (1931), with its supplements, of the American Ornithologists' Union, has been followed. Forms not recognized in this list have not been included.
