"dashing in and striking down many of the birds before the flock is 

 well under headway." 



In their summer home, Mr. Nelson says the lougspuris "a widely 

 spread circumpolar bird, whose presence is recorded from nearly 

 very point visited by explorers along the shores of the arctic coast. 

 . . . When they arrive early in May/' he adds, " the ground is still 

 largely covered with snow with the exception of grassy spots along- 

 southern exposures and the more favorably situated portions of the 

 tundra, and here may be found these birds in all the beauty of their 

 elegant summer dress. The males, as if conscious of their handsome 

 plumage, choose the tops of the only breaks in the monotonous level, 

 which are small rounded knolls and tussocks. The male utters its 

 song as it flies upward from one of these knolls, and when it reaches 

 the height of ten or fifteen yards it extends the points of its wings 

 upwards, forming a large V-shaped figure, and floats gently to the 

 ground, uttering, as it slowly sinks, its liquid tones, which fall in 

 tinkling succession upon the ear, and are perhaps the sweetest 

 notes that one hears during the entire springtime in these regions."
