COLAPTES HYBRIDUS, Baird. 
Colaptes ayresii, Aup. Birds Am. VII, 1843, 348 ; pl. 494. 
? Geopicus chrysoides, MaLuerse, Rey. et. Mag. Zool. IV, 1852, 553. (Differs from C. auratus in wanting red nape ) 
Sp. Cu.— Yellow shafts or feathers on wing and tail combined with red or red spotted cheek patches. Orange shafts combined 
with a weil defined nuchal red crescent. Ash colored throat combined with black cheek patch, or yellow shafts. Shafts and 
feathers intermediate between gamboge yellow and dark orange red. 
By the above name I intend to cover a remarkable series of woodpeckers from the upper 
Missouri and Yellowstone, combining the characteristics of the Colaptes auratus and mexicanus 
in proportions varying with almost each individual, and leading irresistibly to the conclusion 
that they are descendants of originals of the species mentioned above, mixed up by inter- 
breeding of successive generations, to a degree unparalleled in the annals of ornithology. I 
have, in the two preceeding articles, gone into much detail in respect to the characters of 
Coiaptes auratus and meaicanus, and under the first named head have shown the particular 
point of difference.
