The liandswiie varit'ty known as // r/n/an.i is generally spoken of Ly all 

 familiar wit li its liaKits, as well 

 as with its appearanee, as tin' 

 almost u.xact counterpart of 

 the lied-shduldered Hawk, re- 

 l)laciug that i'onu on the west 

 coast. 



In regard to its distinctive 

 spceitic iiahits hut little is as 

 yet known, but it is proliai)lo 

 they are not essentially dilVer- 

 ent I'roni those ol' the /i/tni/ns, 

 Dr. Cooper bearing positive 

 testimony to tliis I'act. Me 

 found this Hawk connnon in 

 the .southern ])art of the State, _ 

 especially near San Diego, l)ut 

 he did not meet with any in 

 the Colorado Valley. ()n his 

 apjU'oach to one of them, it 

 would always ily oil' from its 

 usual perch, circling up high 

 into the air, and uttering sliort 

 shrill screams in rajjid succession in the mannei' of the linrntnx. He no- 

 ticed a itair constantly at one place near a ranch, and sujiposed they were 

 about building there, but was not al)le to iind the nest. 



Among the memoranda of Mr. Xantus, made at Fort Tejon, Cal., is one 

 dated ]\Iay 0, mentioning the finding tlie nest of this species. It contained 

 I'our eggs, was built in an old decayed trc(!, in a swam]), and was aliont 

 fifteen feet from the ground. The nest was large and made of sticks.
