No. 20.] THE BIRDS OF CONNECTICUT. 345 



Palmer. All the Vireos are very useful protectors of forest and 

 fruit trees." (Judd, " Birds of a Maryland Farm.") 



Insects of many kinds are given to the young and occasionally 

 raspberries and blackberries. They are among our most useful 

 birds. 



Red-eyed Vireo ( Vireosylva olivaced) . — " From the stomachs 

 of eighteen of this species were taken fifteen caterpillars ; five 

 other larvae ; eight beetles — among them five weevils, one long- 

 horn and one darkling beetle ; seventy heteropterous insects — 

 among them sixty-seven chinch-bugs ; sixteen winged ants ; one 

 ichneumon ; five dragon-flies ; two dipterous insects — one of 

 them Tahanus afratus; and seven dogwood berries. Of thirty- 

 six other specimens examined, fifteen had eaten caterpillars; two, 

 other larv^; nine, beetles — among them two Coccinella mali; 

 three, grasshoppers ; two, ants ; two, moths ; four, insects none of 

 which were identified ; and seven, fruit or seeds, among which 

 were raspberries, dogwood berries, berries of prickly ash, and 

 sheep berries." 



Yellow-throated Vireo {Lanivireo Havifrons) . — " Of twenty- 

 one specimens examined, seven had eaten caterpillars — among 

 them geometers ; seven, beetles — among them weevils and a 

 buprestis ; three, grasshoppers ; two, moths ; two, heteropterous 

 insects — among them leaf-hoppers ; three, dipterous insects." 



Warbling Vireo ( Vireosylva gilvus) . — " Of sixteen speci- 

 mens examined, eight had eaten thirty- four caterpillars; two, five 

 beetles, among which were a ladybird {Coccinella sex-notata), 

 and .a Dibrotica duodecim-punctata : three, three heteropterous 

 insects ; two, two crane-flies ; one, grasshopper ; two, twenty-eight 

 insects' eggs; and one, dogwood berries." (King, in Chapman, 

 " The Economic Value of Birds to the State.") 



The White-eyed Vireo (Vireo griseus griseus) is a common 

 summer resident of the tangled thickets of our southern border. 

 " The food of this species in early summer is almost exclusively 

 small insects, which it gleans with great assiduity. In eastern 

 Massachusetts, like all its kindred, it feeds eagerly upon the young 

 larvae of the destructive cankerworm, and doubtless, in the wilder 

 portions of the country, is of considerable service in restricting 

 the increase of this scourge." (Baird, Brewer, and Ridgway, 

 " North American Birds.")
