On the Pacific Coast the Robin is only a winter visitant in California; a very few remaining to breed, and those only among the hills. They reach Vancouver Island early in March, and are very abundant. In New England, where the Robins are held in great esteem, and where they exist under very favorable circumstances, their numbers have very largely increased, especially in the villages. They cause not a little annoyance to fruit cultivators by their depredations upon the productions of the garden, especially cherries and strawberries. They are a voracious bird, and no doubt destroy a large quantity of small fruit, but there is abundant evidence that this is more than compensated by their destruction of the most injurious insects, upon which they wage an incessant war. The investigations of Mr. J. W. P. Jenks and Professor Treadwell establish conclusively their great services in this direction. The experiments of the latter gentleman show that the nestlings of the Robin require a vast amount of animal food, forty per cent more than their own weight being consumed by the young bird within twenty-four hours, and, what is more, demonstrated to be necessary to its existence.

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.
