348 Ferruginous Rough-legged Hawk. 
Archibuteo ferrugineus (LICHT.) GRAY. 1840. 
Apparently rare in Manitoba as Thompson-Seton does not 
record it in his “ Birds of Manitoba.” In Zhe Auk, Vol. X, 49, how- 
ever, he states that a fine specimen of this bird is now in the Mani-

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, Assa. Two nests were taken

to the Cypress Hills and south to Milk River. It was common in 
the West Butte and along St. Mary River north of the 4gth 
parallel. It seems to be purely a prairie species, not being 
recorded from the Saskatchewan.

Ist May, 1892. On 16th I shot a fine female that had a nest ina 
dead poplar about 12 feet from the ground. The nest was made

Another nest in live poplar had the same number of eggs and 
was lined with the inner bark of dead poplar. This bird was 
tolerably common all summer. In May and June, 1894, a number 
-of nests were found in box elder (Negundo aceroides) at Medicine 
Hat, Crane Lake, and along Skull Creek, and in the Cypress Hills. 
In the summer of 1895, they were found breeding in the same
