388 GEOLOGICAL SURVEY OF CANADA. 



at Binscarth on the upper Assiniboine, I found a crow's nest in a 

 bluff of poplar trees. It was in a crotch of a large poplar, about 

 8 feet from the ground, and was one of the most beautiful speci- 

 mens, of bird architecture I ever examined, excluding, of course, 

 all pensile nests. It was a large structure of sticks, twigs and 

 bark strips, with a very deep cavity lined with fine fibres and 

 beautifully finished off with a coating of cow's hair. It contained 

 four eggs. {Thompson- Seton.) This species frequently nests in 

 firs and spruces near Ottawa. Its nests are built of sticks and 

 twigs, lined with moss, strips of bark and fine grass. Eggs, four 

 to six; green, spotted with blackish-brown. {G.R.White.) Nest 

 taken on June 2nd, 1895, ^ "^'l^ "P ^^e west fork of Old Wives' 

 Creek, contained four fresh eggs. The base of the nest was of 

 coarse sticks and the inside was lined with the inner bark of ash- 

 leaved maple, in which tree it was built. Other nests were taken in 

 thickets of willow and other brush in many parts of the prairie. 

 {Macoun.) March 2nd, 1902, a crow was seen to be carrying 

 nesting material at Fredericton; even at that time migration had 

 hardly begun, this being a bird that had remained in that vicinity 

 all winter. I have found a full set of crow's eggs April 21st. At 

 one time a nest was found and both birds were sitting on the eggs. 

 The cavity of the nest was much larger than ordinarily. Think- 

 ing when seeing both birds fly from the nest it might be two 

 females laying in one nest, I climbed and found that the ne?t 

 contained five nearly incubated eggs. A nest was found here ' 

 containing ten eggs. {W. H. Moore ^
