WARBLING VIREO. 



season I had added a dozen or more (to me) new 

 birds to my list." 



The Red-eye is always hunting among the foliage 

 tor his insect food, and is most commonly seen with 

 upturned head, carefully gleaning from the under side 

 of leaves. He sings, or talks, as he works, in short 

 musical sentences, given between mouthfuls, 

 " Where's a worm? Where's a caterpillar? Where's 

 a worm? he queries as he goes, answering his own 

 questions very comfortably to himself," as MisS Mer- 

 riam says. While his summer diet is chiefly insects, 

 late in the season he eats berries and wild grapes, and 

 Dr. Warren tells us " His white shirt front is often 

 soiled with the bright juices of the fruits on which 

 he feeds." 



The basket nest of the Red-eye is woven of strips 

 of grape-vine bark and lined with finer material. It 

 hangs rather low from a forked twig, about which it 

 is so firmly woven that it often withstands the winter 

 storms in good condition, so well indeed that one 

 must look twice to ascertain if it be old or new. The 

 eggs, 3 to 4, are white, lightly speckled at the larger 

 end. 



This Vireo has a loud complaining note when 

 troubled, somewhat like the Catbird's mewins: crv.

 to make their acquaintance you must take your opera-
