Nests in Trees, Bushes, or Vines 
663a. Sycamore Warbler: D. d. albilora Ridgw. 
Closely resembling the preceding, but rather smaller, and 
without yellow in front of the eye. 
Breeding Range—‘‘ The Mississippi Valley north to Kansas, south- 
ern Indiana, and southern Illinois ; east to western South 
Carolina” (Chapman). Davie gives the range as, ‘‘ North 
to Lake Erie and southern Michigan, and east to western 
North Carolina.” 
The nest is usually placed in sycamore trees. ‘‘It is com- 
posed of fine shreds of vegetable material intermingled with 
short, slender twigs as the base.” 
The eggs are identical in markings with those of the yellow- 
throated warbler, but are slightly smaller in size. 
667. Black-throated Green Warbler: Dendroica virens 
(Gmel.) 
Adult 6—Upper parts olive green ; two white wing bars, bright 
yellow cheeks, and line over eye; under parts, throat, 
breast, and streaks on sides of flank black; belly white, 
more or less tinged with yellow. 
Adult 2—Very similar, the throat having yellow mixed with 
black. Length—5. Io. 
Breeding Range—The higher parts of the Alleghanies to South 
Carolina, and northward from Connecticut and northern 
Illinois. 
The nest is a beautiful compact structure of small twigs 
(usually of hemlock or spruce), lichen, moss, grass, wool, and 
bark, lined with plant down, hair, grass, and feathers. It is 
generally placed in a coniferous tree, at a height varying from 
ten or fifteen to fifty feet. The eggs, 3 or 4in number, are creamy 
white, spotted, specked, and rarely blotched with orange brown, 
chiefly at the large end. Size—.64 x .52. 
These birds during the breeding season inhabit almost ex- 
clusively the dense coniferous or mixed forests, where in June 
they build their nests.
