256 BIRDS OF ONTARIO. 



quickly, with a few bold strokes of their long, pointed wings, they will 

 rise to the former height, and dash hither and thither as before. 



Poets, in all ages, have sung the praises of their favorite birds, 

 .and even to-day, from the unromantic plains of Chatham come the 

 following lines on the habit of the Nighthawk, just described : 



" With half closed wings and quivering boom, 

 Descending through the deepening gloom, 

 Like plummet falling from the sky, 

 Where some poor moth may vainly try 



A goal to win 

 He holds him with his glittering eye 



And scoops him in." 



Towards the end of August, when the first frosts begin to cut off 

 their supply of insect food, large gatherings of Nighthawks may be 

 .seen in the evenings moving toward the south-west, not in regular 

 order like ducks or pigeons, but skimming, darting and crossing 

 each other in every imaginable direction, and still with a general 

 tendencv toward the south, till darkness hides them from our view.

The Swift is a late comer, and while here seems ever anxious to 

 make up for lost time, being constantly on the wing, darting about 

 with great rapidity, sometimes high overhead, sometimes skimming 

 the surface of the pond, often so closely as to be able to sip from the 

 water as it passes over it, ov snap up the insects which hover on the 

 ;surface.
