Eange. — America, from Colombia and Cuba north over eastern 

 United States to Ifewfoundland, Ontario and Manitoba. Breeds from 

 Gulf of Mexico, north. Winters from Florida, south. 



Nest, pensile; in fork of twig, three to thirty feet up; of fine bark, 

 grass and spiders' webs, outside beautifullj decorated with lichens. 

 Eggs, 3-5'; white, with spots of chestnut-brown, umber and black, 

 chiefly at the larger end; .79 by .58. 



Details of structure of Yellow-throated Vireo. Natural size. 



Common migrant. Summer resident in some numbers northward, 

 and more rarely southward. Breeds. Mr. Eohert Eidgway reports 

 it breeding in Knox and Gibson counties, where he says it frequents the 

 luxuriant forests of the bottom lands. Mr. Y. H. Barnett found a 

 nest in an elm on the bank of a creek in Brown County, May 16, 

 1897. In the southeastern portion of the State it frequents wooded 

 hillsides especially, where there is a considerable undergrowth. 

 "While it may breed there, I have no knowledge that it does. I found 

 them paired at Brookville, May 4, 1886. Dr. F. W. Langdon notes 

 that a few remain and breed about Cincinnati, 0., and Mr. A. M. 

 Hadley reports it breeding near Eiehmond, Ind. Messrs. L. A. and 

 C. D. Test report it breeding at Lafayette, and from there northward 

 it appears to nest more numerously. 



Dates of earliest and latest first arrival are as follows: Bloom- 

 ington, April 17, 1886, April 20, 1896; BrookviUe, April 19, 1881, 

 May 7, 1885; Spearsville, April 19, 1894, April 24, 1895; Richmond, 

 April 22, 1897; Greencastle, April 25, 1895; Lafayette, April 26, 1897, 

 April 28, 1895; Chicago, 111., April 21, 1895; Petersburg, Mich., April 

 27, 1888, May 5, 1889. 



It has a "fine and peculiar song, commencing always with a clear 

 and mellow queery, queery." It is quite different from that of either 

 the Eed-eyed or the Warbling Vireo. It has an alarm note that 

 reminds me of that of a wren. I have only heard its song in the 

 spring, though it is said to sing sometimes until early September.
