162 THE CONDOR Vote. X Accipiter cooperi. Cooper Hawk. Abundance doubtful. My only record of this bird is of one seen March 20, 1902, three miles south of Coilbran, but judging from notes from adjoining sections I am inclined to think it is not of uncommon occurrence. I have frequently seen a hawk at a distance which I took to be this species, but the above is the only definite record. [Accipiter atricapillus. American Goshawk. Generally distributed thruout the State {luring winter and not uncommon in the mountains during the summer. Probably occurs in the County at all times of the year but never commonly.] Buteo borealis calurus. Western Red-tail. Summer resident, common; winter resident, not common. By far the most abundant big hawk in the summer, arriving late in March and breeding early in May. Breeds commonly from 6,000 to 9,000 feet and in the Buzzard Creek country (8,000 to 9,000) builds in scrub oaks from 8 to 15 feet above the ground, and also in the sandstone ledges. In the valleys it nests commonly along the creeks, selecting tall cottonwoods or spruces and building at from 30 to 60 feet above ground. Incubated eggs have been taken as early as May 7th at 8,000 feet. I have included it as a winter resident upon the strength of having seen it February 8 and March 12, 1902, sometime before the bird move- ment starts. Mr. Sullivan has seen it bnly as a migrant at Grand Junction. Buteo swainsoni. Swainson Hawk. Summer resident, common. With the exception of the Western Red-tail this is the commonest big hawk found in the County. It arrives with the Red-tail and breeds early in May. Probably a very few remain thruout the winter in the lower parts of the County. Mr. Sullivan states that this is probably the commoneat of the larger hawks and buzzards around Grand Junction and they probably breed, but he has never seen them during De- cember and January. [Archibuteo ferrugineus. Ferruginous Rough-leg. Probably a rather common resident, omitted from the list thru being confused with the other large hawks in the absence of speci- mens in the hand.] Aquila chrysaetos. Golden Eagle. Resident, common. The rocky portion of the County furnishes ideal homes for this great bird and they occur in all suit- able localities. They are much more in evidence during the winter than in sum- mer, owing to the fact that they nest very early (March and April) and then wander up to high altitudes for the summer, returning to the valleys when the food supply on the Mesa is cut off by snow. During the winter they live largely on carrion, but so far as my observations go are not depredatory. I have not found them nesting but have seen the birds almost every day during March and April. Mr. Sullivan reports two pairs nesting near Grand Junction in 1903 and 1904, one pair on the cliffs of the Grand Mesa and one on the cliffs of Pinon Mesa about 10 miles south of the city. Haliaaeetus. leucocephalus. Bald Eagle. Mr. Sullivan considers the Bald Eagle more or less common on the Grand River. He says: "In the summer of 1904, I saw more Bald Eagles than Golden. On July 11, 1904, I counted 9 soar- ing about 300 to 500 feet up, just east of the city. Returning home from the east during February, 1904, I counted 7 Bald Eagles along the Grand River either in the cottonwoods or flying along about 75 feet up, below DeBeque. It was not at all uncommon for us to see two or three of these birds going northward almost daily between March and August, 1904. I cannot say that they breed in the cir- cumscribed area to which my observations were mostly confined, but at any rate I never saw so many eagles in the locality (both kinds) as I saw during the summer of 1904, and reports' from the higher elevations should show that both kinds breed." Mr. Floyd Smalley reports two birds of this species from the head of Plateau Val- le? - at about 6,500 feet. One was a summer record and the other a fall record.
