*146. Buteo borealis, /?. calurus, (Cass.). — IVcstcrn Bed-tailed Saivk. 



This Hawk was oftener seen at Soda Springs in tlie fall of 1877 than 

 any other species of the genus. Two of the four which were shot there 

 were young birds, nearly grown. I have seen one specimen, which was 

 shot at ]Marys\'ille about November 1. 



Eed-tailed Hawks are ver;s' common constant residents of the valleys, 

 and in summer are quite as common in the mountains.

*147. Buteo lineatus, />. elegans, (Cass.). — Iied-bcUied Hawk. 



Buteo elcyans is verj' common at Stockton in summer. It Avas quite 

 almndant as late as October 1, 1878, but was rarely seen after the 15th, 

 although individuals were observed November 10 and IG. f A nest seen 

 June 8, in nearly horizontal limbs of an oak, was forty or fifty feet fi-oni 

 the ground, irregular in shape, about eighteen inches thick, and. Judging 

 by the leaves attached to some of the tAvigs, was built of dead and living 

 twigs and sticks. The cavity of the nest must have been sliallow, as its 

 occupant could be seen at a short distance from the base of the tree.

148. Archibuteo lagopus, />. sanctijohannis, (Gmel.). — American Eoitgii-Iefffjed Hawk. 

 The Rough-legged Hawlv is the only Arehilmteo I have been able to 

 shoot at Stockton this season, and I think this is the first I have seen 

 since September C. It had a larger companion. I saw two of these 

 Hawks in a cage at Marysville last winter ; both had been slightly 

 winged. The^' were very tame. I have seen only three or four l)lack- 

 plumaged specimens in the i)ast three years. One of these was at Big 

 Trees last August, and one at Stockton April 1, 1878.
