NATURE STUDY IN SCHOOLS. 153 



Arrives from the south about May 1st, and frequents deciduous trees in 

 open groves or on the margins of woodlands, hence often by road sides and in 

 parks. Breeds from Florida to Northern New England, but rarely north of 

 Massachusetts. 



Song. Distinctly divided into three series of notes given with a rather 

 harsh, forcible intonation. The syllables are something like these, " Do you 

 see me ? Do you hear me ? Here I am ! * These utterances are given with 

 sufficient pause between the series to render the separation of the notes very 

 apparent. 



Nest. Often built in an apple or other fruit tree, when such a tree is not 

 far from some woodland, but sometimes on the margin of a woodland in a 

 forest tree. The nest is seldom placed high and is probably the most char- 

 acteristic and easily distinguished of all our vireos. Like all of them, the 

 nest is purse-shaped, hanging below the fork of the twigs in which it is placed, 

 but the outside of the structure, which is made up of strips of bark, grass, 

 etc., neatly and compactly woven together, is usually covered with lichens.

^Blue-lieaded Virefc. 



The eggs are also quite characteristic, being large for those of vireos, and the 

 spottings are not only large, but are most always brown, not black in color 

 as is usual in most species. 



The yellow- throated vireo leaves New England about the second wee]k in 

 September to winter in South America. 



2 Solitary or Blue-headed Vireo* Dark gTeenish above; top of 

 head dusky bluish; prominent ring, around eye, white. Beneath, white., 

 tinged on sides with greenish. Wing bands, white. 



Arrives from the south often as early as the third week in April, and 

 frequents woodland^ seldom appearing in spring in the open country.
