CATALOGUE OF CANADIAN BIRDS. 263 



Nests on the top of clififs, not on the side Hke the duck hawk. (A. 

 P. Low.) 



This form of .4. lagopus is abundant in the Anderson district as 

 specimens have been obtained from all parts of the surrounding 

 forest to the borders of "the barrens," as well as from the Arctic 

 coast. Over seventy nests were collected during the period of 

 exploration treated of by these notes. About fifty-five of them were 

 built in the crotches of trees not far from the top and at a height 

 of twenty to thirty feet from the ground. They were externally of 

 sticks, twigs and small branches, rather comfortable, lined with hay, 

 mosses, down and feathers. The remaining fifteen were situated 

 near the edge of steep cliffs of shaly rock on the face of deep ravines 

 and on declivitous river banks, and these were usually made of 

 willow sticks and twigs, but with a thicker lining of hay, moss and 

 other soft materials. The eggs varied from three to five, never 

 more than the latter number, and their contents were like those of 

 some other birds' eggs gathered by us, in different stages of in- 

 cubation in the same nest. (Macfarlane.) 



A rare summer resident in northern Saskatchewan and northern 

 Alberta from where I have received both eggs and skins. I have 

 sets of eggs taken by Mr. L. Dicks at Hamilton inlet, Labrador, 

 May 17th, 1897, also sets taken by Mr. Stringer at Mackenzie bay, 

 Arctic America. This is the common hawk of Herschell island, where 

 it builds its nests on the cliffs. They consist of a mass of weeds and 

 grass and contain usually four eggs. I have several sets from Her- 

 schell island. (W. Raine.) 



348. Ferruginous Rough-legged Hawk. 



Archibuteo ferrugineus (Light.) Gray. 1849. 



Apparently rare in Manitoba as Seton does not record it in his 

 "Birds of Manitoba." In The Auk, Vol. X, 49, however, he states 

 that a fine specimen of this bird is now in the Manitoba Museum, 

 taken by Mr. Hine. Dr. Coues found it breeding in the Pembina 

 mountains on the International Boundary in July, 1873. 



This is not a rare species in the prairie region. In 1895 the writer 

 found it at Old Wives creek, Sask. Two nests were taken at this 

 point on 27th May, eggs in one just hatched. The species was seen 

 at Wood mountain and everywhere on the prairie west to the Cypress
