This is especially noticeable among birds—the red-breasted nuthatch, brown creeper, winter wren, golden-crowned kinglet, soli- tary vireo, black-throated green warbler, black- i)urnian warbler, Canada warbler, and slate-colored jiinco attaining much larger populations in the Smoky Mountains of Tennessee than in northern Ontario. In addition the veery, black-throated blue warbler, and often black and white warblers become numerous.

In addition the veery, black-throated blue warbler, and often black and white warblers become numerous. This constitutes a variation in the boreal forest biociation (Stewart and Aldrich 1952) which may be designated the Appalachian jaciation. \Mien hemlock, which reaches its best develop- ment in the Appalachian Mountains, and spruce-fir forests occur in the same region, some bird species adaptable to both show a definite preference for one over the other. In Table 23-1 it is evident that the red-breasted nuthatch, brown creeper, winter wren, veery, golden-crowned kinglet, and slate-colored junco prefer the spruce-fir forest, while the black- capped chickadee, possibh' the solitary vireo, black- throated blue warbler, black-throated green warbler, blackburnian warbler, and Canada warbler prefer hemlock forests. A similar differentiation of bird populations in these two forests is also evident in.
