ATTRACTIVE QUALITIES.--His pretty plumage, tricks, and great sociability would be enough to make him charming. He is soon tamed, so as to come upon the table and eat from a plate or the hand; his cheerfulness and agility must also give pleasure, always in motion, and bowing after every hop and calling "_sisri_;" but he is particularly valued on account of his song. This song is generally more perfect and altogether superior when he is caged than when hopping about the room. There are however exceptions. The red-breast sings throughout the year, but in spring his voice is most brilliant and his melody most enchanting. In a country residence it is very easy to teach this bird to go and come, whether reared from the nest or caught full grown. THE BLUE-BREAST. Motacilla Suecica, LINNÆUS; La Gorge bleue, BUFFON; Das Blaukehlchen, BECHSTEIN. This bird may be considered as intermediate between the redstart and the common wagtail, having very strong points of resemblance with both. Its length is five inches and a half, of which the tail occupies two and a quarter. The beak is sharp and blackish, yellow at the angles; the iris is brown; the shanks are fourteen lines high, of a reddish brown, and the toes blackish; the head, the back, and the wing-coverts are ashy brown, mottled with a darker tint; a reddish white line passes above the eyes; the cheeks are dark brown, spotted with rust red, and edged at the side with deep ash grey; a brilliant sky blue covers the throat and half way down the breast; this is set off by a spot of the most dazzling white, the size of a pea, placed precisely over the gullet, which, enlarging and diminishing successively, by the movement of this part when the bird sings, produces the most beautiful effect. Some males have two little white spots on the throat, some even have three, while others have none; these latter are probably very old, for I have observed that as the bird grows older the blue deepens, and the orange band becomes almost maroon. It is easy to distinguish the female; when young she has a celestial blue tint on the sides of the throat; this tint deepens with age, and forms two longitudinal lines on the sides of the neck; no orange band; the throat and gullet are yellowish blue, edged longitudinally with a black line; the feet are flesh-coloured. HABITATION.--When wild this species exists all over Europe[94]. It is a bird of passage, and when returning towards the north, in the beginning of April, it stops in large flights near streams, in hedges, and damp fields, comes even into courts, and on the dunghills of farms, if surprised by snow and a severe return of cold. In the summer it frequents those parts among the mountains abounding with water; in August it approaches cabbage fields enclosed by hedges or bushes. It is very seldom that one or two pairs build in our country.
