Birds of Oregon and Washington 125 



common, known as Hutton's, and another very 

 rare, bearing the name of Mr. A. W. Anthony 

 Anthony's Vireo. 



THE WARBLING VIREO. 



GENERAL DESCRIPTION : 



Upper parts : clear grayish-olive. 

 Under parts : whitish. The sides are yellowish. 

 Length, 5 to 5.55 inches. 



Found in tops of shade-trees in town, soon after 

 arrival. Then they disappear for nesting, and return 

 later. 



This member of the Vireo family is distributed 

 over nearly the whole of North America. I 

 have heard him sing in New England, in the 

 southern Middle States and in Minnesota. And 

 here again " His continuous flowing warble with 

 an alto undertone " (Chapman), may be heard 

 late in May in the thick foliage of our shade- 

 trees ; but he may not easily be seen, even with 

 a glass. His song will be heard there morning 

 and afternoon, though not toward evening. It 

 is said by some to resemble that of the Purple 

 Finch. He sings while in constant motion, 

 seeking his food.
