PINE WARBLER. 

 671. Dendroica vigorsi. 5M$ inches. 



Greenish yellow above, brighter below; two white 

 wing bars and white spots on outer tail feathers ; female, 

 duller and grayer. 



Found only in tracts of coniferous trees, except during 

 migrations, when they are often in company with other 

 kinds of Warblers. They like dry hillsides covered with 

 scrub pines and are often quite abundant in such locali- 

 ties. They are rather quiet in their manners, creeping 

 about among the tree tops like Black and White Warblers 

 and occasionally giving their clear little trill. 



Song. Nearest like that of the Chipping Sparrow, 

 but easily distinguishable; a long, clear trill. 



Nest. A small, compact structure of black rootlets 

 lined with hair; placed in the extreme tops of scrub 

 pines, where it is very difficult to see them; eggs white 

 specked with reddish brown (.62x.50). 



Bange. Eastern N. A., breeding from the Gulf north 

 to southern Canada ; winters in southern U. S,
