a ravine in that district, which we could not assign to any other 

 species ; it was a very cumbrous pile, composed of large sticks 

 and the dry "ribs" of buffaloes. 



Pigeon-Hawk, Falco columbarius. — A common species in the 

 Souris district, preying on small birds. 



American Sparrowhawk, Falco sparverlus. — A few pairs bred 

 in the vicinity of Moose Creek. The birds which I dissected had 

 been feeding on grasshoppers. 



American Long-eared Owl, Asio ivilsonianus. — Only met 

 with on the Souris River, near Oxbow, Nov. 5th, when I saw 

 half-a-dozen. The example which I shot to identify the species 

 had been feeding on mice. 



Short-eared Owl, Asio accipitrinus. — This owl was common 

 on the Souris River in September, and at Dalesbro' after the last 

 days of October. I shot one on Nov. 8th, and saw several others, 

 though the snow lay a foot deep on the prairie. 



Snowy Owl, Nyctea nyctea. — Although the Snowy Owl is 

 believed to be exclusively a winter visitor to this region, instances 

 of its lingering on its winter hunting-grounds far into spring are 

 forthcoming. For example, a Snowy Owl, which I examined in 

 the flesh, had been obtained alive by J. N. Davis as late as the 

 20th May. In the autumn the first Snowy Owls, three in number, 

 made their appearance on Sept. 29th, and the species was fairly 

 represented by the middle of October. An example which I met 

 with on Nov. 17th, appeared to be perfectly white, but its great 

 wariness defeated my attempts to stalk it, though I shot another 

 individual of the same species on the following day. 



Belted Kingfisher, Ceryle alcyon. — In the neighbourhood 

 of Long Creek we often watched Belted Kingfishers waiting for 

 their prey, perched on some bough overhanging the water. 



Flicker, Colaptes auratus. — When camping on the banks of 

 the Souris River, we constantly saw Golden-winged Woodpeckers; 

 indeed they often perched on our tent when we were miles away 

 from trees. Those which I dissected had been feeding on ants. 



Whip-poor-will, Antrostomus vociferus. — This species was 

 numerous at Moose Mountain, where it bred. 



Night-Hawk, Chordelles virginianus sennetti. — This species 

 breeds numerously near Dalesbro'. During the day the birds 

 are generally to be found squatting on ploughed land or upon a 

 stone upon the prairie. During the first hours of the morning,
