July, 1908 BIRDS ON THE NAVAJO RESERVATION IN NEW MEXICO 147 



mention of mountains means the Chiisca range, while river, of course, is the San 

 Juan, a muddy, turbulent, treacherous stream. 



Acknowledgments are due Mr. Joseph Grinnell for identification of doubtful 

 species and subspecies. 



Lophortyx gambeli. Gambel Partridge. A friend living at Aztec several miles 

 from Shiprock, up the river, told me one of these birds spent part of one winter 

 around his haystack. 



Meleagris gallopavo merriami. Merriam Turkey. Turkeys, probably this var- 

 iety, are said to be rather common in the oak, pinyon and juniper zone at the west 

 end of the Chusca Mountains. Indians frequently bring them for sale to the post 

 traders' stores near the mountains, but they usually remove wing and tail feathers 

 at least, before delivering. 



Zenaidura macroura. Mourning dove. A few stay all winter along the river. 

 In summer they become very numerous, frequenting the sunflower and bee-plant 

 thickets, probably eating the seeds. They nest freely in cotton wood groves along 

 the river and also in the shrub patches. 



Cathartes aura. Turkey Vulture. Common in early spring and in late summer 

 and autumn. 



Accipiter cooperii. Cooper Hawk. Seen occasionally in groves along the river 

 where they seem to prey upon the doves. 



Buteo borealis calurus. Western Red-tail. Seen along the river bluffs where 

 they nest, and also back in the mountains. Fairly common. 



Buteo swainsoni. Swainson Hawk. Noticed among the groves but not 

 numerous. 



Archibuteo ferrugineus. Ferruginous Rough-leg. Three seen: one along the 

 river and two at "One-Eye-Water" spring, about fifteen miles south of the river. 



Aquila chrysaetos. Golden Eagle. Seen occasionally. A pair nested on a 

 bluff a few miles up the river from Shiprock. 



Falco mexicanus. Prairie Falcon. A few noted but they seem rare. 



Falco columbarius. Pigeon Hawk. Two seen among the cottonwoods, one of 

 which was secured. 



Falco sparverius. Sparrow Hawk. Common along the river bluffs and the 

 rocky buttes on the desert plains. 



Asio wilsonianus. lyong-eared Owl. Two seen several times in a thicket of 

 willows and "squaw-bush," Rhus aroniaiica. 



Bubo virginianus pallescens. Western Horned Owl. Heard several times in 

 the mountains but not seen. 



Speotyto cunicularia hypogaea. Ground Owl. Seen on the mesas back from 

 the river. Noticed an entire family, eight or nine, in the shade of a bush several 

 feet from the hole one hot day. 



Dryobates villosus monticola. Rocky Mountain Hairy Woodpecker. Resident 

 in groves along the river and also in the mountains. A pair nested in a cottonwood 

 not far from the school and the male in particular displayed much anxiety when- 

 ever the nest tree was approached. Several times he followed me from tree to tree 

 for a number of rods, calling down maledictions on m}^ head. 



Dryobates pubescens homorus. Batchelder Woodpecker. Nesting in groves near 

 the river. Not numerous. 



Sphyrapicus thyroideus. Williamson Sapsucker. Two young males seen in the 

 pinyon belt on the Chusca Mountains. 



Colaptes cafer coUaris. Red-shafted Flicker. Found in winter and early spring
