DENDROICA TOWNSENDI (Townsend) TOWNSEND'S WARBLER HABITS This warbler always reminds me of our familiar black-throated green warbler, which it resembles slightly in color pattern but more particularly in its habits and its drowsy song. Its voice is as much associated with the northwestern forests of tall firs as is that of our eastern bird with the pine woods of New England. Its breeding range is confined to the coniferous forests from Prince William Sound and the upper Yukon in Alaska south to Washington and east to southwestern Alberta and western Montana, but it is better known as a migrant through the Rocky Mountain region in general and as a winter visitant in California. Samuel F. Rathbun writes to me from Seattle, Wash., that Townsend's warbler is widely distributed throughout that region. "It is found in the lowlands to some extent as a summer resident, but by far the greater number of the birds will be found summering in the more mountainous and unsettled parts of the region. In some parts it is abundant. During the migrations I have noted it following the deciduous growth and nearby conifers along water courses, but when settled in its summer home, it is almost entirely restricted to the high conifers, a habit that seems to be followed even during rainy and stormy days. I am of the opinion that it must nest at a considerable height, for on several occasions I have seen the birds carrying material into trees at a height of over one hundred feet." Taylor and Shaw (1927) write: "On entering the great forest of the Pacific Northwest, with its solitude, the deep-shaded grandeur of its brown-barked pillars and its stillness, one can almost imagine himself in a different world. Incessantly repeated, apparently from the very crowns of the trees, comes the song of the Townsend warbler, denizen of upper foliage strata. Found in early summer from Alaska south to the State of Washington, the Townsend warbler finds on Mount Rainier approximately the southern limit of its breeding range." Similar haunts seem to have been chosen wherever the species has been found breeding.
