Centurus uropygialis Baird. — Grila Woodpecker. 



At Fort Mojave Dr. Cooper "found tliis Woodpecker abundant in 

 winter, when tliey fed chiefly on the berries of the mistletoe ( Viscum), 

 and were rather shy. They had a loud note of alarm, strikingly similar 

 to that of Phainopeiila nitens, which associated with them in the mistle- 

 toe boughs." 



Ilelancrpes torquatiis (Wils.) Bonap. — Lewis's Woodpecker. 



Kot noticed by Dr. Cooper in the southern portion of the State, al- 

 though it is not an uncommon species throughout the wooded areas of 

 the northern part. 



Colaptes auratus (Liun.) Swains. — Yellow-shafted Flicker. 



Mentioned as probably occurring, by Mr. Eidgway, who noticed sev- 

 eral individuals, but was unable to definitely determine. Several feath- 

 ers shot from one specimen presented the pure bright gamboge-yellow, 

 without the faintest trace of orange. Whether this may or may not have 

 been hybridus, it is impossible to state with certainty, though it is more 

 than probable that it was the typical auratus, both on account of the 

 geographical considerations and the absence of the orange tint, which 

 is seldom, if ever, absent in liyhridus. 



Colaptes auraiiis Jiyhridus (Baird) Eidgw. — "Hybrid" Flicker. 



A specimen obtained in Washoe Valley by Mr. Eidgway has, accord- 

 ing to this observer, the " general appearance of typical mexicamis, hav- 

 ing ashy throat and scarlet 'moustaches,' but occiput with a distinct 

 scarlet crescent, and the red of the remiges and rectrices inclining de- 

 cidedly to orange." Dr. Cooper found several specimens at Fort Mojave 

 which he considers a mixture of mexicanus and auratus, including as one 

 variety the form described by Audubon as C. ayresii, synonymous with 

 the above. 



Colaptes auratus mexicanus (Swains.) Eidgw. — Eed-shafted Flicker. 



Common. Along the Colorado, Dr. Cooper found this bird very shy, 

 probably on account of their being nuich hunted by the Indians for their 

 bright feathers. 



ALCEDINID^. 



Ceryle alcyon (Linn.) Boie. — Belted Kingfisher. 



Common in favorable localities. Mr. Eidgway found it resident in 

 the lower valleys, but only a summer visitant in the mountains. 



Ceryle americana cabanisi (Tschudi) Coues. — Texan Kingfisher. 



The occurrence of this diminutive species along the southern border 

 of the United States, and its presence in the Colorado Valley at several 

 I)oints between Fort Mojave and Fort Yuma, where Dr. Coues noted it, 

 may be sufficient to warrant us in predicting its probable capture within
