Henshaw on Birds observed in New Mexico. [January 



males of the former species were more numerous than ever. This fact is 

 attributed to a migration from somewhere further north, though this locality 

 is, in truth, about the most northern limit of the species in the Rocky 

 Mountains. 



A single S. riifus was seen September 15. It was the last bird of the 

 season. 



56. Stellula calliope. Calliope Hummingbird. — This, the most dim- 

 inutive of our Hummers, is rather numerous in summer in the locality 

 in question, much further north than which it does not go. The species 

 has not yet been detected in Colorado, though I doubt not but that the 

 higher mountains of the southern portion of that State afford a summer 

 home for some of them. It is a curious fact in connection with the 

 history of this species, as well as that of the 5. rufus., that while both of 

 them range far to the northward in the Sierra Nevada, reaching Wash- 

 ington Territory, and even going beyond into Alaska, they yet decline to 

 visit even the middle portion of the Rocky Mountains, but confine their 

 range to their southern parts. The Calliope Hummer is, as compared 

 with the other species mentioned, a rare bird. It is also much less obtru- 

 sive, and in the contests of its larger neighbors it takes no part. When as- 

 sailed, as it promptly is b_y the other kinds, it at once darts away to 

 another spot where it can feed without molestation. It appears to be 

 timid in every way, so much so that it is not an easy bird to collect. An 

 utterly unaccountable fact noticed in connection with this species was 

 the apparent rarity of females. Up to August 10 I had seen perhaps half 

 a dozen, though constantly on the watch for them, while I had certainly 

 seen not less than ten times that number of males. Subsequent to that 

 date I saw a few more, but nothing like the number of males. 



By September the young were numerous in certain localities, notably 

 in a large sunflower patch. 



57. Cypseloides niger borealis. Black Swift. — A single one was 

 seen in September, evidently migrating. 



58. Phalaenoptilus nuttalli. Poor-will. — ^ Evidently a rare species in 

 this particular locality. Two only were obtained. This species is ex- 

 tremely local and may be abundant in one locality and entirely wanting a 

 few miles away. 



59. Picus villosus harrisi. Harris'.s Woodpecker. — Numerous as a 

 summer resident. 



60. Picus pubescens gairdneri. Gairdner's Woodpecker. — Not un- 

 common, though much less common than the preceding, which, indeed, 

 appears to be the case almost everywhere where found. 



61. Picoides tridactylus dorsalis. Striped -backed Three -toed 

 Woodpecker. — Rather common as a resident. Inhabiting the pine 

 woods comparatively little, but frequenting the stretches of dead and 

 fire-blackened timber. 



62. Sphyrapicus varius nuchalis. Red-naped Woodpecker. — Com- 

 mon as a summer and fall resident. Lives entirely among the deciduous 

 trees, as aspens, etc.
