THE SWALLOW-TAILED KITE. 393 



the courting season, when the male reaffirms his fondness for his life-long 

 mate by circling about her as she sits upon the tree-top; or he measures the 

 height of his devotion by ascending to the clouds before her, and dashing 

 himself at her feet again with shrill cries of Killy, hilly, kitty. To hear the 

 snarling clamor of the birds, one would think that they were not getting 

 on nicely, but this is a mistake, for the high-pitched conversation is really 

 very amiable in character, and neither bird would think of parting from its 

 consort for however brief a space of time without a screamed farewell of 

 unquestionable tenderness. 



The eggs, which seldom have any softer resting place than the chips 1 ir 

 rotten wood which the Woodpeckers have left them, are among the hand- 

 somest of oological treasures. The lime of the shell, still plastic, has been 

 generously sprinkled with cinnamon, and a warm glow imparted to the whole. 

 Incubation lasts three weeks, and the yi mug. when hatched, are covered with 

 a thick white down which gives them a rather tidy appearance, in spite of 

 their enormous eyes. 



The food of the Sparrow Hawk consists largely of insects, of which 

 grasshoppers and spiders are the most noteworthy. Mice and shrews are also 

 eaten, and in winter, when the Hawks are much less common, small birds. 

 The Sparmw Hawk has cultivated a discriminating taste for English Spar- 

 rows, and has, I believe, almost left off preying upon other sorts. It 

 deserves rigid protection everywhere, both in village and field.
