1908] BIBDS. 51 



Geog. Dist. Southeastern United States, as far north as Mary- 

 land. 



W. Va. Dist. ^Ir. Doan says he found this species in considerable 

 numbers along the head-waters of Middle Fork River. Scott re- 

 ports that a male and female were taken by Mr. W. S. Edwards in 

 Kanawha County some years ago. 



Nest In tall trees. No record of the breeding of this species 

 In W. Va. 



Food As in the case of so many of our Warblers, very little 

 accurate information has been gathered concerning their feeding 

 habits. Of course all the birds of this family feed principally 

 upon insects, but the exact economic status of the various species 

 is not known. Said to gather most of their iood from the extremi- 

 ties of limbs, among the pine needles which grow there. 



667. Black-throated Green Warbler (Dendroica virens). Male 

 and female. The black on the throat of the male is not well defined 

 till bird is mature. A common and very pretty species. 



Greog. Dist. Eastern North America, west to the Plains, and 

 north to Hudson Bay Territory. 



W. Va. Dist. A common migrant. In the mountains the bird 

 remains throughout the summer and breeds. 



Nest In tall tree. Breeds in our state. 



Food Caterpillars, curculios and other beetles, small bugs, vari- 

 ous Plymenoptera, small locusts, and cankerworms are recorded 

 as the common food of this Warbler. 



671. Pine Warbler (Dendroica vigorsii). A pair of adults. 



Geog. Dist. Eastern United States. 



W. Va. Dist. Recorded from this state by Brewster, Doan. and 

 Eifrig. I have observed this species occasionally, but not often. 



Nest Far up in tall trees, mostly coniferous trees. Four to five 

 spotted eggs. 



Food Weed and Dearborn say, "It is undoubtedly the particu- 

 lar guardian of the pines, about which it remains until very late 

 in the season, for it feeds mainly on insects that infest pine trees. 

 It is able to subsist to some extent on the seeds of pines." 



672a. Yellow Palm Warbler (Dendroica palmarum hypoclinj- 

 sea). Male and female adult. More than most of the Warblers, 

 this spoeies is found along fences and in open fields. May bo roadilv 

 recognized by the constant wag of its tail.
