COLAPTES HYBRIDUS, Baird. 



Colaptes ayresii, Aud. Birds Am. VII, 1843, 348 ; pi. 494. 



? Geopicui chrysoides, Malherbe, Rev. et. Mag. Zool. IV, 1852, 553. (Differs from C. auratus in wanting red nape ) 



Sp. Ch. — Yellow shafts or feathers on wing and tail combined with red or red spotted cheek patches. Orange shafts combined 

 with a well 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 Golaptes 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 

 Golaptes auratus and meaiicanus, and under the first named head have shown the particular 

 point of difiierence.
