Mr. A. Scliott obtained a specimen on the Cohnado liiver in Southern Cali- 

 fornia, and Dr. Giunbel and Dr. A. L. Heermann sjieak of it as common 

 throughout that State, while Dr. Cooper and Dr. Siiekley nunition it as fre- 

 quent both in Oregon and in Washington Territory. xV single specimen was 

 taken by Mr. Salvin in (Juatemnla. Dr. Cooper states that this Hawk is 

 often killed about the farm-yards of "Washington Territory, where it seizes 

 on chickens before the ve.y eyes of the owner, ilarting down like lightning, 

 and di.sappearing again Ixi'ore he can see what ha.s caused tl'> di.sturbance. 

 It is said to be a constant resident, and to breed within the Teriitory. 



Mr. Audubon describes the iliglit of this Hawk as rai>id, protracted, and 

 even, and as ])erformed at a short distance from the ground, or over the for- 

 est. It is said to move along in a silent gliding manner, and with a swift- 

 ness even sni)erior to that of the Wild Pigoon, rarely deviating from a 

 straight cour.se except to .seize its prey, and sehlom mounting in the air in cir- 

 cles. It is very bold and daring, Mr. Audulxm having known one to attack 

 and kill a cock much larger and heavier tiian itself. It frecpiently attacks 

 and kills the common Huffed Grouse. It breeds in especial abundance in 

 the Middle States, and particularly along the baidvs of the Potomac liiver. 

 I have received reliable information of its nesting in Vermont, ^lassachu- 

 setts, Ohio, Illinois, Wisconsin, Maryland, Virginia, and South Carolina, and
