ings round the crown of the oaks, and its flight can sometimes 

 then be watched against the half-lit sky. It is extremely- 

 rapid and skilful, and the activity of its mazy motion is 

 emphasised by its silence. The nightjar flies as silently as 

 an owl ; though moths and beetles cannot be alarmed by 

 noises, like rats or mice, yet a harsher flight might set up 

 disturbing currents of air which would be equally effective 

 in scaring the prey. Very owl-like, too, is its cry of

 this ancient slander, except that the rough, dry goat pastures 

 in many parts of Europe are a favourite haunt of this lover 

 of warmth and dryness.

 more chirping than the nightjar's, but there is no very close 

 likeness between the irregular and fitful scraping of a grass- 

 hopper and its steady reeling cry. It is much more like the 

 sound of a fisherman's well-oiled reel, and as the bird haunts 

 the same banks as the fisherman at his favourite evening;
