been taken several times at Charlotte Harbor, in Florida and is 

 thus entitled to a place in our fauna. 



The eggs of this species are three in number, of a brilliant white 

 delicately tinted with pink, and marked with a few fine red and 

 red-brown spots, usually about the larger end."

139 VIREOSYLVIA GILVA. 



WARBLING VIREO. 



This Vireo breeds abundantly from Virginia to Nova Scotia, and 

 in all the Northwestern States. It arrives in the Middle States 

 about the 15th of April and in New England early in May. In 

 Ohio it begins to build about the middle of May. 



The nest is usually suspended in the fork of twigs at the extrem- 

 ity of a branch, and at the height of from twenty to fifty feet from 

 the ground. I have most frequently found the nest placed in the 

 branches of the Sycamore trees along the banks of streams. They 

 are usually sheltered almost entirely from view by overhanging . 

 leaves. The typical nest is a beautiful structure that hangs like a 

 little basket between the small twigs, firmly secured by strips of 

 fine bark woven around the twigs. It is composed of flaxen 

 fibres, stems of plants and vegetable substances. It is lined ex- 

 clusively with fine grasses. 



The eggs are usually five in number and have a beautiful pure 

 white ground-color, sparingly spotted at the larger end with mark- 

 ings of dark-brown. They measure .70 by .56. 



139a. VIREOSYLVIA GILVA SWAINSONI. 



WESTERN WARBLING VIREO. 



The nests of this species are not distinguishable, except in the 

 necessarily varying materials, from those of the Eastern species. 

 The eggs are the same.
