The females being all arrived, the pairing season at once commences. Several males are seen flying in pursuit of one, until, becoming fatigued, she alights, receives the addresses of her suitors, and soon makes a choice that establishes her the consort of one of them. The "happy couple" immediately retire from the view of the crowds around them, and seek along the margins of some sequestered pond or damp meadow, for a place in which to form their nest. An Alder bush or a thick tuft of rank weeds answer equally well, and in such places a quantity of coarse dried weeds is deposited by them, to form the exterior of the fabric which is to receive the eggs. The nest is lined with fine grasses, and, in some instances, with horse-hair. The eggs are from four to six in number, of a regular oval form, light blue, sparsely spotted with dusky.
Now is the time, good-natured reader, to see and admire the courage and fidelity of the male, whilst assiduously watching over his beloved mate. He dives headlong towards every intruder that approaches his nest, vociferating his fears and maledictions with great vehemence, passing at times within a few yards of the person who has disturbed his peace, or alighting on a twig close to his nest, and uttering a plaintive note, which might well prevent any other than a mischievous person from interfering with the hopes and happiness of the mated Redwings.
The eggs are hatched, and the first brood has taken flight. The young soon after associate with thousands of other striplings, and shift for themselves, whilst the parent birds raise a second family. The first brood comes abroad about the beginning of June, the second in the beginning of August. At this latter period, the corn in the Middle Districts has already acquired considerable consistence, and the congregated Redwings fall upon the fields in such astonishing numbers as to seem capable of completely veiling them under the shade of their wings. The husbandman, anxious to preserve as much of his corn as he can, for his own use or for market, pursues every possible method of annoyance or destruction. But his ingenuity is almost exerted in vain. The Redwings heed not his efforts further than to remove, after each report of his gun, from one portion of the field to another. All the scarecrows that he may choose to place about his grounds are merely regarded by the birds as so many observatories, on which they occasionally alight.
The corn becoming too hard for their bills, they now leave the fields, and resort to the meadows and the margins of streams thickly overgrown with the Wild Oat and other grasses, upon the seeds of which they feed with great avidity during the autumnal and winter months. They then associate partially with the Reed Birds, Grakles, and Cow-pen Buntings, and are seen to move from the Eastern to the Southern Districts, in such immense and thick flocks as almost to cloud the air.
The havock made amongst them is scarcely credible. I have heard that upwards of fifty have been killed at a shot, and am the more inclined to believe such accounts that I have myself shot hundreds in the course of an afternoon, killing from ten to fifteen at every discharge. Whilst travelling in different parts of the Southern States, during the latter part of autumn, I have often seen the fences, trees and fields so strewed with these birds, as to make me believe their number fully equal to that of the falling leaves of the trees in the places traversed by me.
Towards evening they alight in the marshes by millions, in compact bodies, settle on the reeds and rushes close above the water, and remain during the night, unless disturbed by the gunners. When this happens, they rise all of a sudden, and perform various evolutions in the air, now gliding low over the rushes, and again wheeling high above them, preserving silence for a while, but finally diving suddenly to the spot formerly chosen, and commencing a general chuckling noise, after which they remain quiet during the rest of the night.
Different species of Hawks derive their principal sustenance from them at this season. The Pigeon Hawk is an adept in picking the fattest from their crowded flocks; and while they are in the Southern States, where millions of them spend the winter, the Hen-harriers are seen continually hovering over them, and picking up the stragglers.
The Marsh Blackbird is easily kept in confinement, and sings there with as much vigour as when at full liberty. It is kept in good order with rice, wheat, or any other small grain. Attempts have been made to induce these birds to breed in confinement, but in as far as I have been able to ascertain, have failed. As an article of food, they are little better than the Starling of Europe, or the Crow Blackbird of the United States, although many are eaten and thought good by the country people, who make pot-pies of them.
I have represented a male and a female in the adult state, a male in the first spring, and a young bird, and have placed them on the branch of a Water Maple, these birds being fond of alighting on trees of that kind, in early spring, to pick up the insects that frequent the blossoms. This tree is found dispersed throughout the United States, and grows, as its name indicates, in the immediate vicinity of water. Its wood is soft, and is hardly used for any other purpose than that of being converted into common domestic utensils.
