240 GEOLOGICAL SURVEY OF CANADA. 



No examples of this bird were secured byrfle in northern 

 Alaska, nor have I seen any. Several specimens from Kadiak are 

 the only ones known from Alaska. {Nelson.) Both on the main- 

 land and Vancouver Island, B.C. In my experience rare. {Fan- 

 nin.) Tolerably common miigrant at Chilliwack, B.C. ; rather 

 scarce in the Cariboo district of British Columbia in winter. 

 {Brooks.), Sumas and Osoyoos Lake. (Lord.) One seen at 

 Vernon and a specimen seen at the same place in the collection 

 of Mr. Pound. Another shot on Vancouver Island is in the pos- 

 session of Mr. Lindley of Victoria. Considered a very rare bird 

 on the Pacific Coast. {Rhoads.) 



B'RSeding Notes. — First observed on Hudson Bay north of 

 Great Whale RiVer, 28th June, 1896; It breeds on nearly all the 

 hig-h cliffs all the way across^ Ungava District from James Bay 

 to Ungava Bay. On 13th July, Mr. Riussell found a nest with 

 three eggs, incubation far advanced. I found a nest on a cliff 

 at east end of Seal Lake 3'rd August in which the young were 

 about half grown. The nest was a mere mass of sticks lined with 

 dry grass. This is the common large hawk of the country.

• This form' oi A. letgefus i's abundant in the Anderson district as 

 speciWifens 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 20- to 30 fleet from the ground. They were externally of sticks, 

 tvcigs audi small branches,, rather comfortable, lined with hay, 

 mosses, down and feathers. The remaining fifteen were situated 

 near the edge of steepi cliffs [of shady rock on the face of deep 

 ravines and on declivitous ri'Ver banks, and thtse were usually 

 made of willow stiieks and twigs, but with a thicker lining of hay, 

 moss and other soft materials. The eggs vatited! from three to 

 five, never more than thie latter number, and their contents were 

 like those of some other birds' eggs gathered by us, in differed 

 stages of incubation in the same nest. {Macfarlane.y 



A rare summer resident in northern Assiniboia 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,
