WARBLERS 105 



spring comes from his tropical winter home almost to our 

 doors. In the summer he seeks the seclusion of coniferous 

 forests and the higher branches of spruce or hemlock. 

 There his nest is made sometimes 80 or more feet above 

 the ground, and in late May or early June the white eggs, 

 spotted, speckled and blotched with brown, are laid. The 

 Blackburnian's song is described by Miss Paddock in 

 "Warblers of North America" as "very shrill and fine, 

 growing even more shrill and wiry as it rises toward 

 the end." 



YELLOW-THROATED WARBLER 

 Dendroica dominica dominica. Case 5, Fig. 18 



A gray Warbler with a yellow throat. L. si. 



Range. Southeastern States, nesting north to Maryland; 

 wintering from central Florida southward. 



Washington, rare S. R., rather common late in July and Aug.; 

 Apl. 19-Sept. 4. 



The loud, ringing ching-ching-ching, chicker, cherwee of 

 the Yellow-throated Warbler is one of the characteristic 

 bird songs of spring in southern woods. The bird usually 

 sings from the upper branches of tall trees, often cypresses, 

 in Florida, but further north, from pines, where he can 

 be far more easily heard than seen. The nest is placed 

 30-40 feet from the ground and the white eggs, thickly 

 marked with shades of brown, are laid in April. 



The Sycamore Warbler (D. d. albilora, Case 5, Fig. 19) 

 is a nearly related race of the Yellow-throat which inhabits 

 the Mississippi Valley nesting as far north as southern 

 Michigan and wintering in the tropics. It differs from the 

 Atlantic coast form in having a smaller bill and no yellow 

 in front of the eye. As its name implies, it favors sycamore 

 trees.
