 Other similar instances have been recorded. 



The notes of this bird consist of a series of shrill and 

 varied twitters, somewhat resembling those of a Swallow. 

 In spring it often mounts into the air, and, rising high, fre- 

 quently falls for a distance and then recovers itself, twit- 

 tering fiercely all the time, as if engaged with an imaginary 

 antagonist. It appears to be pursuing insects, which it some-

 grain and fruit, click beetles, grasshoppers and 

 crickets, wasps, wild bees, ants, and flies are 

 prominent among the food materials of this 

 bird. Among the flies taken are house flies 

 and several species that trouble cattle ; but

smaller insects, like mosquitoes, gnats, and beetle, natural 

 midgets, are not ignored. Leaf hoppers and slze " 

 many other bugs are taken ; and a great variety of cater- 

 pillars, mostly of the hairless species, are eaten or fed to the 

 young. This bird is destructive to moths of many kinds, 

 among them the gipsy moth. In two and one-half hours 

 seven of these birds were seen to take seventy-nine male and
