THE PLAIN SPARROW.
The Plain Sparrow (Pyrgitopsis simplex) is a remarkable species, inhabiting the wooded country of Eastern Soudan, where it is frequently to be seen near the huts of the natives. In size it is larger than most of its congeners, its length being about six and a half inches, and the span of the wings ten and a half inches. The body is slender, and the beak much elongated; the plumage, as its name indicates, is of very uniform colour; the head and neck mouse-grey, the back and wing-covers rusty brown, the wing and tail quills dark brown, edged with a faint rust-red; the lower part of the body is of a light reddish grey, the throat somewhat lighter, and the belly whitish, the eye light reddish brown, the beak black, and the feet reddish horn colour.
This species is found over the whole of Central and Southern Africa, where it lives in pairs or small parties, being rarely seen in large flocks; its habits resemble those of our Field Sparrow, but, unlike that bird, it often frequents the depths of forests. The nest is built in holes of trees, or in the straw roofing of the native huts. Its voice is similar to that of other Sparrows, and the breeding season commences early in spring. We are unacquainted with the appearance of the eggs.
THE GOLDEN SPARROW.
The Golden Sparrow (Chrysospiza lutea), also a native of Africa, is one of the most beautiful members of this family. The head, neck, and entire under part of the body are of a golden yellow, the mantle reddish brown, the small upper wing-covers black, the wing and tail quills dark grey, edged with reddish brown. The female is very like that of the Common Sparrow, her tints, however, being more golden, and her throat yellow. The young male is like its mother, but brighter. In size the Golden Sparrow resembles the Common species.
Well-watered plains, abounding in mimosa-bushes, afford the shelter most agreeable to these birds, and from such localities they sally forth in large flocks to fall upon the fields of corn or grass. They generally fly over a very limited extent of country, and exhibit so little timidity that they will allow a man to approach quite close to them before taking alarm; they are thus easily brought down by a shot, which only drives the rest of the party to a short distance. Before the rainy season, when the ground is parched and barren, the Golden Sparrow visits the villages and small towns in hope of finding food in the surrounding farmyards and gardens, and though at first rather shy, soon loses all fear of man.
Incubation takes place during the period of the heavy rains, the flocks dividing into pairs about the month of August, keeping at no great distance from each other, and often building close together. The nest, like that of other Sparrows, is constructed, without much art, of such materials as happen to be in the neighbourhood, and is placed but a few feet above the ground. The eggs, three or four in number, are white, spotted with brown, and about eight lines in length. The young are seen flying with their parents by the end of September or October. The moulting season is in the month of January, and by June or July the coats of the adult birds have acquired their greatest beauty. We have never seen the African Golden Sparrow in a cage, even in its own country, for though striking in plumage, it is entirely deficient in song.
THE ROCK SPARROW.
The Rock Sparrow (Petronia rupestris) is most undoubtedly to be classed with the preceding birds, though differing from them in shape, colour, and habits. The body is compact, its length six and a quarter inches, and breadth across the wings nine and a half inches, the female somewhat less. The beak is comparatively strong, and the plumage very plain, resembling that of the female House Sparrow. The back is greyish brown, marked with blackish-brown and greyish-white spots; the upper tail-covers grey, and striped, as is the forehead, with olive brown; over the eyes passes a lighter streak, and the tail-feathers have a white spot on the under side. In winter the beak is of a brownish grey, in summer of a yellow tint, the upper mandible being darker than the under; the eyes are brown, and the tarsus reddish grey. There is but little difference in the appearance of the sexes after they have attained maturity, and females are often found as beautifully marked as the male. The young are recognisable by a white spot upon the throat.
