Jerdon speaks of this species as shy, unsociable, and very silent during the greater part of the year; but with this last statement we by no means fully agree. Whilst performing their migrations, the two sexes certainly associate in flocks; and during the spring the notes of the males are to be heard both by day and night. The voice of the Calliope is very sweet, and though by no means loud, very clear. As the breeding season approaches the male commences singing still more energetically, and is usually to be seen perched, with inflated throat, wings outspread, and tail raised at a right angle with his body, on the topmost branch of a birch or alder-tree, whilst he perseveringly endeavours to attract the admiration of his mate who sits beneath, almost entirely concealed from view. The nests of these birds found by Middendorf on the banks of the Taimye were most beautiful works of art, neatly covered with a roof, and approached by a horizontal entrance-gallery excavated in the sand. The nests were found to contain about five blueish green eggs, which were laid in June. In China the Calliope is known as the "Hung-po" (Redbreast), or "Ching-po" (Goldbreast), and is much prized as a domestic favourite by people of all classes: it is constantly kept by the Chinese, not in a cage, but secured to a perch or branch by means of a string tied round the neck. This peculiar and very practical manner of preventing the escape of a bird is, as Swinhoe tells us, very extensively adopted in the Celestial Empire. THE ROBIN REDBREAST. The ROBIN REDBREAST (_Erythaca rubecula_ or _Rubecula silvestris_) is the last member of the family to which our space permits us to allude. In this species the upper mandible is arched and incised immediately behind its curved tip. The feet are of moderate height, and delicately formed; the wings, in which the fourth and fifth quills are the longest, are rather short and weak; the tail is of medium size, and slightly incised at its extremity. The plumage is lax, and of a deep olive-grey upon the upper part of-the body; the under side is grey; the brow, throat, and upper portion of the breast yellowish red. The female is somewhat paler than her mate, and the young are distinguishable by reddish yellow spots on the shafts of the upper feathers; the under side is reddish yellow, with grey spots and light edges to the feathers; the large, expressive eyes are brown, the beak blackish brown, and the feet reddish grey. The length of this bird is five inches and a half, and its breadth eight inches and a half; the wing measures two inches and three-quarters, and the tail two inches and a half.
