Since the publication of the first edition of the 'Color Key' in 1903, the American Ornithologists' Union has issued the Third Edition (1910) of its 'Check-List of North American Birds.' This includes all approved additions to and changes in the preceding edition made since 1903 as well as rulings on a number of cases which were in abeyance at the time the first edition of the 'Color Key' appeared.
Mere changes in nomenclature not affecting the status of a species are given without comment in the preceding Systematic Table, which has been fully revised and brought up to date. To ascertain the correct, current name of any species or subspecies of North American bird the student, after determining its identity in the 'Color Key,' has only to refer to its number in the Systematic Table to learn whether any change has been made in nomenclature. In addition to actual changes in nomenclature due to the detection of errors in earlier names, it should be noted that a third name or trinomial is now employed for each race of a species, and also that an apostrophe is used in connection with the names of birds named for individuals. Throughout the 'Color Key,' therefore, alterations should be made when required by these two changes in method.
All other changes than these simple ones of names are included, with explanations, in this appendix, and the student is urged to make manuscript cross-references on the pages where such changes occur to avoid their being overlooked.
As far as possible the language of the original describer of the new subspecies of birds is here quoted, while the Ranges are mainly from the A. O. U. Check-List.
References to original sources of publication are given only with cases included in the first supplement to the Third Edition (1910) of the Check List. In all other instances reference to the original place of description, etc., is contained in the 'Check-List.'
Pages 29, 127. The North American Kites, Hawks, Falcons, Eagles, etc., are now placed in three families instead of one, as follows: BUTEONIDÆ, containing the Kites, Hawks and Eagles (Nos. 327-352a); FALCONIDÆ containing the Falcons and Caracaras (Nos. 353-363), and PANDIONIDÆ, containing the Osprey (No. 364).
Pages 39, 162, 168. The subfamilies Troglodytinæ and Miminæ are now elevated to full family rank. The Mockingbirds and Thrashers (Nos. 702-712) are therefore the North American members of the Family MIMIDÆ; and the Wrens (Nos. 713-725e) the North American members of the Family TROGLODYTIDÆ.
Pages 39, 162, 168. The subfamilies Sittinæ and Parinæ are now elevated to full family rank. The Nuthatches (Nos. 727 to 730a) are therefore the North American members of the Family SITTIDÆ; and the Titmice (Nos. 732 to 746a, except Nos. 742 to 742c now placed in the Family CHAMÆIDÆ, see beyond) the North American members of the Family PARIDÆ.
Page 63. Cancel No. 94, Puffinus fuliginosus, which proves to be the same as No. 95, Puffinus griseus. The common name, however, is retained and the species stands 95, Sooty Shearwater (Puffinus griseus). Characters as given.

Page 192. Cancel No. 530b, United States specimens of which prove to be merely adults of No. 530. Further west, however, black-backed birds are not found, and this western bird has been described as new. (Consequently after No. 530, add: 530a). Green-backed Goldfinch (A. p. hesperophilus).

Page 236. Cancel No. 821b, Troglodytes aëdon aztecus, which proves to be the same as No. 721a, T. a. parkmani. The common name, Western House Wren, however, is retained in place of the common name Parkman's Wren.
Page 237. After No. 725c add: 725d. Prairie Marsh Wren (T. p. iliacus). "Similar to T. p. palustris, but slightly larger and with the coloration more rufescent, the brown of the upperparts russet-brown to cinnamon-brown or russet, the flanks conspicuously deep cinnamon-buff or cinnamon" (Ridgway).

Pages 240 and 241. The decisions of the A. O. U. Committee on numerous proposed changes in the standing of our Juncos were not published until after the first edition of the Color Key appeared. One new form (No. 567h) has been added to those therein given one (J. o. shufeldti) has been omitted and the following changes have been made in nomenclature:
No. 568. Junco mearnsi, becomes No. 567g, Junco hyemalis mearnsi, and the Range of this form is now given as "Rocky Mountain region. Breeds from southwestern Saskatchewan to southern Idaho and northern Wyoming and Colorado to southern Arizona, southern New Mexico, and northeastern Sonora" (A. O. U.).
No. 567.1 Junco montanus, becomes No. 567f. Junco hyemalis montanus.
No. 571.1 Junco townsendi, becomes No. 567i, Junco hyemalis townsendi.
No. 569 Junco caniceps, becomes No. 570b. Junco phæonotus caniceps.
No. 570a. Junco dorsalis, becomes Junco phæonotus dorsalis.
No. 567a. Junco oreganus, becomes Junco hyemalis oreganus.
No. 567c. Junco oreganus thurberi, becomes Junco hyemalis thurberi.
No. 567d. Junco oreganus pinosus, becomes Junco hyemalis pinosus.
The common names of all the preceding species remain unchanged.
No. 567b. Coues' Junco (Junco oreganus connectens) becomes Shufeldt's Junco (Junco hyemalis connectens), and this form also includes J. o. shufeldti of the 'Color Key,' which is therefore cancelled. The Range of 567b, thus stands as follows:
Rocky Mountain region. Breeds from the coast of southern British Columbia east to west, central Alberta and south to northern Oregon; winters over entire Rocky Mountain tableland to eastern Colorado, Arizona, New Mexico, western Texas, Chihuahua, and Sonora; casual in northern Lower California" (A.
