The song of the Robin is deservedly popular. While many of our birds possess far superior powers of melody, and exhibit a much greater variety in their song, there are none that exceed it in its duration or extent. It is the first bird in spring to open and one of the last to close the great concert of Nature. Their song is earnest, simple, and thrilling, and is said by Audubon to resemble that of the European Blackbird, Turdus merula.
The Robin, when taken young, may be readily tamed, and soon becomes contented and accustomed to confinement. They are devoted to their young, watchful, attentive, and provident. They begin to construct their nest in early spring before the trees put forth their leaves, and often in very exposed positions. The size of the nest, in fact, makes concealment impossible. These nests are sometimes placed in quite remarkable positions, such as the beams of a ship partly finished, and where the carpenters were every day at work, and similar situations indicating a great familiarity. Their favorite place is the horizontal branch of an apple-tree, about ten feet from the ground.
The nest of the Robin is a large and coarsely constructed combination of rude materials. It is composed of a base of straw, leaves, mosses, stems, and dry grasses, upon which a cup-shaped fabric of clay or mud is built. The whole is lined with finer dry grasses and vegetable fibres. They average 5 inches in height and the same in diameter. Their cavity is 2¾ inches deep, with a diameter of 2½ inches.
The eggs of the Robin, which are usually five and sometimes six in number, are of a uniform bright greenish-blue color, liable to fade when exposed to light, but when fresh exhibiting a very distinct and bright tint. They vary in size from 1.25 to 1.12 inches in length, and in breadth from .88 to .75 of an inch. Their mean measurement is 1.18 by .81.
Turdus migratorius, var. confinis, Baird.
CAPE ST. LUCAS ROBIN.
Turdus confinis, Baird, Rev. Am. B. 1864, 29.—Elliot, Birds America.—Cooper, Birds Cal., 9.
Sp. Char. No. 23,789. Entire upper parts and sides of head and neck uniform grayish-ash, with perhaps a faint tinge of olivaceous, less than in eastern specimens of T. migratorius. The central portions of the feathers of the top of head are rather darker than the edges, though almost inappreciably so, and not imparting a general dusky appearance. The chin and throat are white, streaked with ashy-brown. The jugulum and breast are
pale yellowish-buff; the axillars, inner wing-coverts, and sides of the breast similarly, but rather more decidedly colored. The belly and edges of the crissal feathers are white, the hinder parts of the flanks ashy. There is a distinct whitish stripe from the lores over and a quarter of an inch behind the eye; the lower eyelid is also white. The tail-feathers are worn, but there is an indication of a narrow white tip. The feathers of the jugulum, especially of the sides, are tipped with ashy like the back, as in immature specimens of T. migratorius. The greater wing-coverts are tipped with dull white. The bill is yellowish; the upper mandible and the tip of lower tinged with dusky. The feet are pale brown.
The length cannot be given accurately, as the skin is much drawn up. The wing, however, measures 5.10 inches, its tip reaching 1.40 beyond the longest secondary; tail, 4.10; tarsus, 1.20; middle toe and claw, 1.07; exposed portion of culmen, .92; from tip to open portion of nostrils, .60.
