YELLOWxTHROATED WARBLER, 



A. O. U. No. 663. (Dendroica dominlca) 



RANGE. 



The breeding range of these Warblers is in eastern United States, 

 chiefly east of the Alleghenies, where it is found from southern Flori- 

 da to Maryland and casually Pennsylvania. They winter in southern 

 Florida, the Bahamas and the West Indies. 



DESCRIPTION. 



Length, 5 to 5.25 in. The adults of this species are very similar in 

 color and markings, the female being only a trifle duller colored. 



SYCAMORE WARBLER. 



A- O. U. No. 663a. (Dendroica doininica albilora.) 



RANGE AND DESCRIPTION. 



The western form of the Yellow-throated Warbler is most abundant in 

 the lower Ohio Valley, ranging from the Alleghenies in Virginia west to 

 Nebraska and from Michigan and Wisconsin south to the Gulf. It 

 difi'ers from the eastern form in having the lores white or nearly white 

 instead of yellow as in the preceding and in usually having the chin 

 white also. The habits of the two very similar birds do not differ. 



NEST AND EGGS. 



The eastern Yellow-throated Warblers nest commonly in the South 

 Atlantic States, building their homes upon the horizontal boughs of 

 pines or oaks, or sometimes in pendant bunches of Spanish moss 

 something after the style of the Parula Warbler; as a rule their nests 

 are placed at quite an elevation from the ground, the distance varying 

 from fifteen to forty feet. When placed on limbs the nests are made 

 of fine twigs, grasses and shreds of bark and lined with feathers. They 

 lay three or four, and rarely five, eggs of a pale greenish-white color, 

 specked or wreathed with brown and lavender. Size .70 x .50.

 early in April, usually rear their families and commence to take their 

 departure in the latter part of July or August. Their song is loud and
