ROSCOE'S YELLOW-THROAT.

PLATE XXIV. MALE.

The many kind attentions which I have received from the celebrated author of the Life of Leo the Tenth, joined to the valuable advice with which I have been favoured by that excellent gentleman, has induced me to honour the little bird before you with his name.

I shot it in a deep swamp not far from the River Mississippi, in the State bearing the same name, in September 1821. It was flitting amongst the top branches of a high Cypress, when I first observed it, moving sideways, searching for insects, and occasionally following one on the wing. It uttered a single twit repeated at short intervals. It having unexpectedly flown to a distant tree of the species on a branch of which you now see it, I followed it and shot it. It was the only one of the kind I have ever seen, although I went to the same swamp for several days in succession. It proved a male, and was to all appearance in perfect plumage. The gizzard was nearly filled with very minute red insects, found on Cypresses and Pines, the wings of different flies, and the heads of red ants.

In general appearance, this species so much resembles the preceding, that had not its habits differed so greatly from those of the Maryland Yellow-throat, I might have been induced to consider it as merely an accidental variety. On examining it more closely, however, and on comparing it with that bird, I felt, as I now feel, fully confident of its being different.

The species of Oak, on a twig of which it stands, is commonly called the Swamp Oak. It grows to a large size, always near the edges of damp or watery places. The height is from fifty to sixty feet, its diameter from two to three. The branches come off from the trunk at a height of eight feet from the ground, nearly at right angles. The twigs have a similar disposition. The wood is extremely hard and close in the texture, heavier than that of either the Red or the White Oak, and sinks when thrown into water. The Southern States appear to be those in which it thrives best.

THE SONG SPARROW.

FRINGILLA MELODIA, WILS.

PLATE XXV. MALE AND FEMALE.

The Song Sparrow is one of the most abundant of its tribe in Louisiana, during winter. This abundance is easily accounted for by the circumstance that it rears three broods in the year:—six, five, and three young at each time, making fourteen per annum from a single pair. Supposing a couple to live in health, and enjoy the comforts necessary for the bringing up of their young families, for a period of only ten years, which is a moderate estimate for birds of this class, you will readily conceive how a whole flock of Song Sparrows may in a very short time be produced by them.

Among the many desiderata connected with the study of nature, there is one which, long felt by me, is not less so at the present moment. I have never been able to conceive why a bird which produces more than one brood in a season, should abandon its first nest to construct a new one, as is the case with the present species; while other birds, such as the Ospreys, and various species of Swallows, rear many broods in the first nest which they have made, and to which they return, after their long annual migrations, to repair it, and render it fit for the habitation of the young brood. There is another fact which renders the question still more difficult to be solved. I have generally found the nests of this Sparrow cleaner and more perfect after the brood raised in them have made their departure, than the nests of the other species of birds mentioned above are on such occasions; a circumstance which would render it unnecessary for the Song Sparrow to repair its nest. You are aware of the cleanliness of birds with respect to their nests during the whole period occupied in rearing their young. You know that the parents remove the excrements to a distance from them, so long as these excrements are contained in a filmy kind of substance, of which the old bird lays hold with its bill for that express purpose, frequently carrying them off to a distance of forty or fifty yards, or even more. Well, the Song Sparrow is among the cleanest of the clean. I have often watched the young birds leaving the nest; and after their departure, have found it as well fitted for the reception of a fresh set of eggs as the new nest which the bird constructs. I am unable to understand the reason why a new nest is formed. Can you, reader, solve the question?

I have at all times been very partial to the Song Sparrow; for although its attire is exceedingly plain, it is pleasing to hear it, in the Middle States, singing earlier in spring, and later in autumn, than almost any other bird. Its song is sweet, of considerable duration, and performed at all hours of the day. It nestles sometimes on trees, and sometimes on the ground. I have imagined that the old birds, finding by experience the insecurity of their ordinary practice of nestling on the ground, where the eggs are often devoured by Crows, betake themselves to the bushes to conceal their nests from their enemies. But whatever may be the reason, the fact certainly exists, and the nests of the Song Sparrow occur in both kinds of situation. The nest for the first brood is prepared, and the eggs laid, sometimes as early as the 15th of April. The young are out by the first week of May. The third brood is seen by the middle of September. The nest, when on the ground, is well sunk in the earth, and is placed at the roots of tall grasses. It is made of fine grass, and lined with hair, principally horse hair. The number of eggs is from five to seven, usually from four to six, excepting those for the last brood, which I have seldom found to exceed three. They are of a very broad ovate form, light greenish-white, speckled with dark umber, the specks larger toward the greater end. The male assists in the process of incubation, during which one of the birds feeds the other in succession. At this time the male is often to be observed singing on the top of a neighbouring bush, low tree, or fence-rail.

The flight of the Song Sparrow is short, and much undulated, when the bird is high in the air, but swifter and more level when it is near the ground. They migrate by night, singly or in straggling troops. Some of them remain the whole winter in the Middle Districts, where they are not unfrequently heard to sing, if the weather prove at all pleasant. The greater part, however, seek the Southern States, where myriads of Sparrows of different kinds are everywhere to be seen in low swampy situations, such as they at all periods prefer. It is a fine plump bird, and becomes very flat and juicy. It is picked up in great numbers by the Hen-harriers, which visit us for the purpose of feeding on the different kinds of Sparrows that resort to these States in winter from the Middle Districts. In Louisiana, they are frequently seen to ascend to the tops of large trees, and there continue for some time singing their agreeable chant, after which they dive again into the low bushes or amongst the rank weeds which grow wherever a stream is to be found. They feed on grass seeds, some berries and insects, especially grasshoppers, and now and then pursue flies on the wing. On the ground their motions are lively. They continue running about with great nimbleness and activity, and sometimes cross shallow waters leg-deep. To the eastward, they often frequent orchards and large gardens, but seldom approach houses.

I have placed a pair of them on a twig of the Huckleberry Bush in blossom. This species sometimes grows to the height of six or seven feet, and produces a fine berry in great abundance. Huckleberries of every sort are picked by women and children, and sold in the eastern markets in great profusion. They are used for tarts, but in my opinion are better when eaten fresh.
