The nest is always placed near the ground, generally raised from it by a thick bed of dry leaves or sticks; sometimes among bushes, but never in the fork of a bush or tree, or if so, in very rare and exceptional cases. When incubation has commenced, the female is reluctant to leave her nest. If driven off she utters no complaint, but remains close at hand and returns at the first opportunity. They construct their nest early in May, and the young are hatched in the latter part of that month, or the first of June. They raise two broods in the season. The nest, even more loosely put together than that of the Ground Swamp Robin (_T. pallasi_), is often with difficulty kept complete. It is about 3 inches in height, 4½ in diameter, with a cavity 1½ inches deep and 3 in width, and composed of dry bark, dead leaves, stems, and woody fibres, intermingled with grasses, caricas, sedges, etc., and lined with soft skeleton leaves. A nest from Wisconsin was composed entirely of a coarse species of _Sparganeum_; the dead stalks and leaves of which were interwoven with a very striking effect. The eggs, usually four, sometimes five in number, are of a uniform green color, with a slight tinge of blue, and average .94 by .66 of an inch in diameter. Turdus aliciæ, BAIRD.
