Sp. Char. Tail nearly even; the lateral feather shorter. Above, rather dark bluish slate; under parts generally, a patch on the upper eyelids continuous with a stripe behind it along the side of the head and neck, the lower eyelids, two bands across the wing coverts and the edges of the quills, in part, rufous orange-brown; middle of belly white. Sides of the head and neck, continuous with a broad pectoral transverse band, black. Most of tail feathers with a terminal patch of brownish white. Bill black. Feet yellow. Female more olivaceous above; the white of the abdomen more extended; the brown beneath paler; the pectoral band obsolete. Length, 9.75 inches; wing, 5.00; tail, 3.90; tarsus, 1.25.
Young (45,897, Sitka, Aug. 1866; F. Bischoff). Exactly resembling the adult female, having no spots other than seen in the adult plumage; but the pectoral collar is composed only of badly defined blackish transverse crescents, and the upper parts anterior to the rump are of an umber brown tint. The markings about the head and on the wings are precisely as in the adult.
This species does not appear to be liable to any noticeable variation.
Hab. West coast of North America, from Behring Straits to California; straggling to Great Bear Lake. Accidental on Long Island (Cab. G. N. Lawrence), New Jersey (Cab. Dr. Samuel Cabot), and Ipswich, Mass. (Cab. Boston Society Natural History); Iowa (Allen).
Turdus nævius.
Habits. The accidental occurrence of a few specimens of this well-marked bird in the Eastern States is its only claim to a place in that fauna, it being strictly a western species, belonging to the Pacific Coast. It was first discovered by the naturalists of Captain Cook’s expedition, who met with it as far to the north as Nootka Sound. It is only very recently that we have become possessed of reliable information in regard to its breeding and its nest and eggs. Sir John Richardson was informed that it nested in bushes in a manner similar to that of the common robin.
Nuttall and Townsend found it abundant among the western slopes of the
Rocky Mountains, near the Columbia River, in October. In the winter it became still more numerous, passing the season in that region as well as in more southern localities, associating with the robin. From this bird it may be readily distinguished by the difference of its notes, which are louder, sharper, and delivered with greater rapidity. In the spring, before leaving for their breeding-places, they are described as having a very sweet warble.
