Tliis common species was observed nearly everyNvhere in the vicinity 

 of the fertile valleys. It appears to be resident in western Nevada, for it 

 was extremely abundant in July at the Truckee Meadows, where during' 

 the day half a dozen or more were often noticed at one time sailing in broad 

 circles over the meadows. The flight of thi.s Hawk is extremely similar 

 to that of the Golden Eagle, a fact which probably explains why the 

 Indians class it with the Eagles instead of with the Hen Hawks (Biitco)} 

 Most of those seen were in the light-colored, or normal, phase of plumage ; 

 in fact, but one individual was seen which might have been the black jdiase 

 of this species, although it is by no means certain it was not an adult spec- 

 imen of Butco ahbreviatus." This specimen was seen in the latter part of 

 February, high overhead, sailing in a direct line from the eastward toward 

 the Sierra Nevada. Its color was an intense black, relieved by a conspic- 

 uous white patch under the primaries and several distinct bands of the same 



across the tail.
