8o Henshaw on Birds observed in Neiv Mexico. [January 



of a tree where they can be detected onlj by the most patient search. In 

 very inclement weather I presume they ensconce themselves snugly in 

 some of the innumerable cavities in old stubs. 



70. ^salon columbarius. Pigeon Hawk. — Not uncommon. 



71. Tinnunculus sparverius. Sparrow Hawk. — Numerous, chiefly 

 in fall. 



72. Pandion haliaetus carolinensis. Fish Hawk. — Several seen in fall. 

 Very destructive to trout. 



73. Accipiter cooperi. Cooper's Ha\vk. — Common. 



74. Accipiter fuScus. Sharp-shinned Hawk. — Common. 



75. Astur atricapillus striatulus. Western Goshawk. — Several were 

 seen in fall. 



76. Buteo borealis calurus. Western Red-tail. — The most abun- 

 dant of all the Hawks. Very numerous and resident. 



77. Aquila chrysaetus canadensis. Golden Eagle. — Rather common 

 as a summer resident. 



78. Cathartes aura. Turkey Buzzard. — Common. 



79. Columba fasciata. B.\nd-tailed Pigeon. — None of these birds 

 nested near our camp, though they probably did not far away. The 

 latter part of August they were found feeding upon the berries of the 

 Sambncus racemosa, a small shrubby plant, from two to four feet high. 

 Subsequently, when the acorns began to grow large — long before they 

 began to ripen — they appeared to devote themselves exclusively to them, 

 and between the Pigeons and the squirrels, not an acorn was allowed to 

 ripen. The acorns were of the scrub oak, ^uercus uudiilata (two varieties), 

 and are extremely palatable. Pigeons were shot not only with their crops 

 full, but with the gullet crammed up to the very bill. 



80. Meleagris gallopavo. Mexican Wild Turkey. — Turkeys are 

 found all through the mountains, but they are by no means common. 

 As winter approaches they leave their summer haunts and travel down to 

 the foot-hills and the mesas, where they remain till the snow goes, when, 

 like the deer, they return. 



Si. Canace obscura. Dusky Grouse. — Not abundant, though gener- 

 ally distributed through the mountains. 



82. Tringoides macularius. Spotted Sandpiper. — This ubiquitous 

 little Sandpiper was found along the Pecos at various points, and the fact 

 that it breeds at an altitude of about 8000 feet was attested by the presence 

 of young just out of the shell. 



83. Nettion carolinensis. Green-winged Teal. — This chanced to be 

 the only species of Duck noticed. Ducks drop in here by the merest 

 accident in spring and fall, and doubtless at one time or another most of 

 the migrating species occur along the river.
