^°l9?4^^] Bailey, Birds of the Upper Pecos. 353 



Accipiter cooperi. Cooper Hawk. — One was seen near Glorieta on 

 July 4 flying with a small mammal in its claws. 



Buteo borealis calurus. Western Red-Tail. — Red-tailed Buteos w'ere 

 seen about our camps at 8000 and 11,000 feet. 



Aquila chrysaetos. Golden Eagle. — Several eagles were observed 

 over the highest peaks. A young one was seen soaring over Pecos Baldy 

 August 18, the white base of its tail showing brilliantly in the sun. 



Haliaeetus leucocephalus. B.\ld Eagle. — Two or three Bald Eagles 

 were reported at about 8000 feet on the Pecos August 20. 



Falco mexicanus. Prairie Falcon. — A Falcon that Mr. Bailey took 

 to be the Prairie was seen August 14 beating up against a storm, attempt- 

 ing to round the peak of Pecos Baldy. 



Falco sparverius phalcena. Desert Sparrow Hawk. — Near Glorieta 

 a pair of Sparrow Hawks were feeding young inside a Cottonwood knot- 

 hole on July 8. Of the few individuals noted in the mountains one was 

 seen August 11 flying over Truchas Peak (13,300 feet) and another Au- 

 gust 13 flying over Pecos Baldy (12,600 feet). Twice the hawks were seen 

 disputing with Clarke Crows, once at our Hudsonian camp when the hawk 

 and nutcracker took turns chasing each other out of camp. 



Bubo virginianus pallescens. Western Horned Owl. — The remains 

 of a Horned Owl were found near Glorieta and the birds were heard at 

 8000 and 11,000 feet, while a feather of one was found halfway up the 

 peak of Pecos Baldy. 



Ceryle alcyon. Belted Kingfisher. — Mr. Henshaw states that although 

 several kingfishers were seen along the Pecos in the fall they did not 

 breed in the locality, but we found them on the Pecos July 11 and 16 at 

 an altitude of about 7800 and 8000 feet. 



Dryobates villosus monticola. Rocky Mountain Hairy Wood- 

 pecker. — Hairy Woodpeckers were noted at different altitudes, from 7400 

 feet on the lower edge of the Transition zone to 11,600 feet in the Hud- 

 sonian zone. The gizzard of a young male shot was full of hard-bodied 

 insects. At 1 1,600 feet on August 15 a family of grown young were going 

 about feeding themselves, calling and drumming. In watching them 

 the red crown patches of the young were so conspicuous as they turned 

 their heads in pecking at the bark that they suggested a possible advan- 

 tage as recognition marks. Does a parent coming with grubs distinguish 

 its son from its mate a tree away by the red crown .' It is certainly a con- 

 venient mark from the foot of the tree. 



Picoides arcticus dorsalis. Alpine Three-toed Woodpecker. — A 

 pair of Three-toed Woodpeckers were feeding young about our Hudsonian 

 camp at 11,600 feet August 14. An old male and one of the brood were 

 seen on the same tree, the young one picking about for itself while its 

 parent dug larvre out of the live bark and fed them to it. A young Dryo- 

 bates flew down while they were enjoying the meal and finally succeeded 

 in driving them off, although they scolded angrily as they went. The 

 stomachs of two adults and one young were full of the larvje of tree 

 insects.
