BLACK-THROATED GREY WOOD-WARBLER.
[Black-throated Gray Warbler.]

SYLVICOLA NIGRESCENS, Townsend.
[Dendroica nigrescens.]

PLATE CXIV.--MALES.

This is another of the interesting species discovered and named by Mr. TOWNSEND, who informs me that it is called "Ah Kah a qual" by the Chinook Indians; that it is abundant in the forests of the Columbia, where it breeds and remains until winter; and that the nest, formed externally of fibrous green moss, is generally placed on the upper branches of the oak, suspended between two small twigs. Mr. NUTTALL'S notice respecting it is as follows:--"This curious species, so much resembling Sylvia striata, was seen to arrive early in May; and from its song more regularly delivered at intervals, in the tops of deciduous-leaved trees, we have little doubt but that they breed in the forests of the Columbia. On the 23d of May I had the satisfaction of harkening to the delicate but monotonous song of this bird, as he busily and intently searched every leafy bough and expanding bud for larvae and insects in a spreading oak, from whence he delivered his solitary note. Sometimes he remained a minute or two stationary, but more generally continued his quest for prey. His song, at short and regular intervals, seemed like 't shee 't shay t shaitshee, varying the feeble sound very little, and with the concluding note somewhat slenderly and plaintively raised."
