found only in the canons and is not at all abundant. One pair was 

 located near the head of the west branch of Wai-bonnet Canon, where 

 the nest was found by Mr. Gary and myself on June 5. The nest was 

 about twenty feet from the ground and rested on the upper side of a 

 horizontal limb at the point where it leaned against the trunk of an 

 adjacent tree. It required a sharp blow from a stone to flush the 

 female from her set of four beautifully blotched eggs. The nest was 

 left undisturbed for a few days, when I returned with a camera and 

 secured several photographs, two of the female on the nest and one 

 of the nest and eggs. 



I was much interested in the actions of the female during the 

 time which was occupied in taking the photos. The tree containing 

 the nest was surrounded by numerous small trees and shrubs, many 

 of which had to be removed before an unobstructed view of the nest 

 could be secured. During this work the bird sat upon the nest in plain 

 sight of me and not more than twenty feet distant. Whenever a limb 

 gave an extra loud snap in breaking I held my breath for a moment 

 for fear she would fly, but my fears proved to be groundless, for she 

 remained quietly on the nest, only moving her head from side to side, 

 until I started to climb the tree, when she flew. While busy in the 

 tree securing a photo of the nest and eggs the female returned and 

 alighting on a limb about fifteen feet distant sat and watched me 

 closely, now and then shaking herself and pluming her feathers. 



On July 10 I found the second nest of this pair of birds not far from 

 the site of the first. It was in a scrubby pine, about twelve feet from 

 the ground, and was a very flimsy structure in comparison to the other. 

 As an additional proof of its being a second set, the eggs numbered 

 but three, with one immaculate, while all those of the first set were 

 blotched. Here also the female did not leave the nest until the tree 

 was shaken. Both nests were situated in trees growing at the very 

 bottom of the canon and surrounded by a dense growth of deciduous 

 trees. As in other localities, the birds are seldom seen, keeping under 

 cover of the thick growth of trees which fill the bottoms of the canons. 

 At one time while walking along an old "snake" road running down 

 a canon, a chipping sparrow dashed across the path in front of me, 

 closely followed by a sharp-shinned hawk. At sight of me, however, 

 the hawk swerved suddenly and disappeared into the thicket from 

 which it had fiown in pursuit of the sparrow. 



Krider'vS Hawk (Buteo horealis kriderii). — I made the acquaintance of 

 this majestic bird on June 13. It was a foggy, drizzling day and I had 

 started out to systematically explore several caiions to the east of War- 

 bonnet. Having ascended a canon almost to its perpendicular head a 

 chorus of bird cries suddenly sounded somewhere ahead of me. By 

 this time the fog had filled the canon, almost blotting out the sheer 

 semicircular walls of rock which formed its head and it was some time 

 before I could locate the cries of the birds, since they were magnified,
