174 PACIFIC COAST AVIFAUNA No. 14 



na would not be so unusual as might be implied from the range as given in the 

 A. 0. U. Check-List. This, however, is not a strong enough reason to admit to 

 the state list a subspecies of so variable a ])ird as B. horcalis, on sight identifi- 

 cation alone, when so far from its normal range. 



Coccyzus americanus occidentalis Hidgway 



California Cuckoo 

 An Q.Q^^ evidently that of a cuckoo, was picked up at Flathead Lake, July 

 3. 1900 (Silloway, 1901a, pp. 29-30). The bird itself has never been seen in that 

 region. Since this subspecies has been found in nortliern Idaho, it may also occur 

 rarely in northwestern Montana. At any rate it is more likely to have been a 

 subspecies of Coccyzus americanus whose egg was found than C. erythrophthal- 

 mus, whose western limit in eastern Montana lies in a totally different fauna! 

 region. 



Xenopicus albolarvatus (Cassin) 

 White-headed Woodpecker 

 Seen several times in the Gallatin Canyon in summer and fall, a single bird 

 at a time (Thomas, MS). This is rather far east of tlie normal range for this 

 sr»e('ies. It is another case where we uuist wait for a si)ecimen to verify the 

 record. 



Archilochus colubris (Linnaeus) 



JiUBY-TilKOATED HUMMINGBIRD 



Rare in Custer County. Nests said to have been found on the Powder River 

 and in Miles City (Cameron, 1907, p. 390). This species was not observed by 

 Mr. Cameron himself, but by others, who found the nests mentioned. Since 

 iStcllula calUo2)c occurs in the region, it would be easy to mistake the two spe- 

 cies, particularly the females, wliich would be liable to be the only ones seen 

 about the nest. 



Aphelocoma woodhousei (!^>aird) 

 WooDHOUSE Jay 

 Seen at Billings, August 12, 1900 (Jones and Dawson, 1900, p. 32). It 

 seems entirely possiI)le to mistake tlie F'inyon Jay in the field for this bird, par- 

 ticularly if the ol)server had no previous ac(iuaintaiice witli either sj^ecies. Mr. 

 Thomas has been looking for the Woodiiouse Jay about Billings at my rectuest. 

 He writes that the Pinyon Jay is connnon, and he supposed it was woodhousei 

 till he collected one. This was exactly my own experience in Carter County in 

 the winter of 1909. Hntil stronger evidence is ])resented. the case of the Wood 

 house Jay must be considered not proved. 



Corvus cryptoleucus Couch 

 White-necked Raven 

 One seen in Custer County, September 14, 1902 (Cameron, 1907, p. 393).
