Note 6 — Chapter III · THE TURKEY PREHISTORIC
Reading edition
In making this statement, I take the words of Dr. Geo. Bird Grinnell as written on the cork of the bottle containing the specimen to be correct, and not the locality given elsewhere. (The A. O. U. Check-List of North American Birds. Third Edition, 1910, p. 388.) Moreover, the specimen is pure white, which is characteristic of the fossils found in the White River region of Colorado. This is confirmed by Professor Marsh in his article quoted above.
