Mr. Audubon's drawing and description of tiiis bird W(;re taken from a 

 specimen obtained by 1 h: Townsend from the Cohindna IJiver. A number 

 of specimens have been obtained 

 by the various governmciut ex- 

 phiring e.K])edition.s. A single 

 .specimen was tai<en by ^Mr. Dres- 

 ser near San Antonio, in Te.\'a.s. 



Captain lUal-iston (Ibis, ISdl, 

 ]). 317) olitained several s])eci- 

 mens of this JUizzard at the tbrks 

 of the Saskatchewan Itiver, in the 

 stomach of one of which he found 

 three loads. He states that it 

 was (piite abundant in that neigli- 

 borhood. lie adds that Mr. liour- 

 geau jnocured se\eral specimens 

 of the eggs, identified by also ob- 

 taining the parents. These eggs 

 are said to have been white, more 

 or less blotched Mith red. ^Ir. 

 liernard Ross also obtained this 

 bird on the Mackenzie River, 

 where it was rare. 



Tiiis Hawk was observed by :Mr. Dall, in Alaska, a skin having been 

 obtained at Koyukuk, ^lay 20, from an Indian. Mr. Dall stiites that 

 it ])refers the thickets and woody places, is not so often seen as some 

 of tlie other species. It generally builds a very large nest of sticks, and 

 I)egins to lay al)out the last of April. The young are hatched out about the 

 30th of May. It was only a sumnuu- visitor. He found not only tiie bones 

 of I'abliits, scjuirrels, and mice about its nest, but also tho.se ol' ducks, and in 

 one instance part of a white-fi.sh. 



• Dr. Heermann obtained an egg of this species in Northern California, 

 whicli had a yellowish-white ground-color, marked with obscure cloudings 

 of a i)urplish-gray, .nd irregular patches of a light tone of umber brown. 

 It measured li.31 inches in length, aiul 1.84 in lireadth. 



AVe arc indebted to Dr. W. J. Hoffmann for the following interesting note 

 in relation to tlie nesting of this species : " On the 28th of May, 1871, we en- 

 camped on Anteloi)e Creek, forty miles north of the Central I'acific Railroad 

 Statit)ii, Argcnta Nevada. The stream of water, which is small, is fringed 

 with willows, a^■eraging about twelve feet in height. Strolling along the 

 underbrush, I came to the iiesb of the Butco sivainsoni, which was built on 



Buleo swainsoni (mliilt).
