BIRDS OF NEW MEXICO 
taken from the published or manuscript field notes of observers within 
the State (see Itineraries, pp. 15-36)—Jens Ivnudsen Jensen, Ralph 
Todd Kellogg, Aldo Leopold, Dr. Walter Iungerish Mitchell, Milton 
Philo Skinner, and others; but principally from various members of the 
Biological Survey who have worked in the State long enough to add 
life-history material to their distribution notes, that appear under 
“State records”—Clarence Birdseye, .lames Hamilton Gaut, Maj. 
Edward Alphonso Goldman, Henry Wotherbee Henshaw (whose first 
notes were made while on the Wheeler Survey), Ned Hollister, James 
Stokley Ligon, Prof. Dayton Eugene Merrill, Frank Stephens, Dr. 
[Frank] Alexander Wetmore, and George Willett; in addition to material 
obtained during many months of field work throughout the State by 
Mr. Bailey and myself. 
The classification used, in the sequence of Orders and Families, is 
that recommended by Wetmore and Miller 1 and adopted by the Com¬ 
mittee on Nomenclature of the American Ornithologists’ Union. Owing 
to the fact that the Fourth Edition of the A. O. U. Check-List has not 
yet appeared, the nomenclature adopted is, with some exceptions, that 
of the Third (1910) Edition and its three supplements. 
From various members of the Biological Survey, I have received 
ready and generous help; for the identification of specimens, assistance 
in working out ranges of species, and the critical examination of manu¬ 
script, I am indebted to Dr. Harry Church Oberholser; for additional 
help on ranges, I am indebted to Mr. Edward Alexander Preble, and 
for assistance in gathering distribution data from the files of the Survey 
accumulated since the death of Professor Cooke, mainly to his daughter, 
Miss May Thacher Cooke; for the critical examination of the fifty-nine 
bird maps and the preparation of the route and zone maps, I am in¬ 
debted to my husband, Mr. Vernon Bailey, from whom also, as well as 
from Dr. Jheodore Sherman Palmer and Mr. Edward Alexander Preble, 
I have received much valuable criticism, helpful suggestion, and advice.* 
For courtesies extended, I am also indebted to Dr. Witmer Stone and 
Dr. Alexander Wetmore.
