Now gloomy November brings up its cold blasts from the north, and drives before it the Grakles from the Eastern States. They reach Louisiana and all the Southern States when autumn has not yet retired, when the weather is still mild and serene, and the yellow foliage of the wide woods gives shelter to myriads of birds. The Grakles, congregated in prodigious flocks, alight on the trees that border the vast forests, covering every twig and bough in such astonishing masses, that the most unskilful or most avaricious gunner finds no difficulty in satisfying his wish for sport or game. This is the time to listen to their choruses. They seem to congratulate each other on their escape, and vociferate at such a rate as to make one imagine their number double what it is.
Beech-nuts and acorns are now abundant in the woods, having by this time fallen from the trees, and the Grakles roam in quest of them in immense bodies, rising on wing when disturbed, uttering at the same time a tremendous noise, then making a few rounds, and alighting again. They thus gradually clear away the mast, in the same manner as the wild pigeons are wont to do. As the weather becomes colder, they frequent the farms, and even resort to the cattle pens, where, from among the litter and refuse straw, they pick the scattered grains that have fallen from the stores with which the farmer has supplied his stock. They remain about the farms until the commencement of spring. They are easily caught in traps, and shew little fear when seized, biting so severely as often to draw blood, and laying hold with their claws in a very energetic manner.
During the winter of 1821, I caught a number of them, as well as many other birds, for the purpose of sending them alive to Europe. The whole of my captives were confined together in a large cage, where they were well fed and watered, and received all necessary attention. Things went on favourably for several days, and I with pleasure saw them becoming daily more gentle. An unexpected change, however, soon took place, for as the Grakles became reconciled to confinement, they began to attack the other birds, beating and killing one after another so fast that I was obliged to remove them from the cage. Even this did not prevent further breach of the peace, for the strong attacked and killed the weak of their own race, so that only a few remained in the end. The Grakles thus mangled, killed and partially devoured several Cardinal Grosbeaks, Doves, Pigeons, and Blue Jays. I look upon this remarkable instance of ferocity in the Grakle with the more amazement, as I never observed it killing any bird when in a state of freedom.
What I have said respecting the Purple Grakle (which by some is improperly named the Boat-tailed Grakle) refers particularly to the habits of those in the south, where some of them are found at all seasons. I shall now speak of those of the Western and Middle States. Most of these birds leave the south about the middle of February, setting out in small detached flocks. They reach the State of New York in this straggling manner about the middle of May. Their migratory flight is performed in short undulating lines, resembling small segments of very large circles. It may be explained in this manner. Supposing the bird poised in the air and intent on moving forwards, it propels itself by a strenuous flap of the wings, which carries it forward in a curve, along which it ascends until it attains the level of its original point of departure, when it flaps its wings again, and performs another curve. In this form of flight they pursue their long journey, during which they keep up a continual low chattering, as if they were discussing some important question. When they reach Pennsylvania, they commence the avocations which I have already described, and are seen following the plough, while their kindred that have been left in Louisiana are probably by this time feeding their young, as the difference of climate between these latitudes leaves the northern states a month later in their seasons than the southern.
In the Northern States these birds construct their nests in a much more perfect, and therefore more natural manner. A pine tree, whenever it occurs in a convenient place, is selected by preference, its dense foliage and horizontal branches being well adapted for nidification. There the Grakle forms a nest, which from the ground might easily be mistaken for that of our Robin, the Turdus migratorius, were it less bulky. But it is much larger, and instead of being placed by itself, is associated with others, often to the number of a dozen or more, on the horizontal arms of the pine, forming tier above tier, from the lowest to the highest branches. The centre of the nest is what I would call saddled on the bough, the materials being laid so that the nest is thinner in its middle part and thicker at the two opposite sides, so as to have a firm hold. It is about six inches in diameter outside, and four inches within, the depth being the same, and is composed of grass, slender roots and mud, lined with hair and finer grasses. I had a white pine-tree in one of my fields on Mill Grove Farm, on which many of these birds bred every spring, when some mischievous lads frequently amused themselves with beating down the nests with long fishing-rods, to my great annoyance. Some of the Pennsylvanian farmers, from a very laudable motive, have given out that Grakles are fond of pulling up the garlic plant, so injurious to the pastures of the Middle States; but I am sorry to say this assertion is by no means correct, and were these good people to look to the Grakles for the clearing of their fields from that evil, they might wait long enough.
The flesh of the Purple Grakle is little better than that of the Crow, being dry and ill-flavoured, notwithstanding which it is frequently used, with the addition of one or two Golden-winged Woodpeckers or Redwings, to make what is here called pot pie, even amidst a profusion of so many better things. The eggs, on the contrary, are very delicate, and I am astonished that those who are so anxious for the destruction of these birds do not gratify their wishes by eating them while yet in embryo in the egg. In some parts of Louisiana, the farmers, or, as they are styled, the planters, steep the seed corn for a few hours in a solution of Glauber's salt, to deter the Grakles and other birds from eating the grains when just planted, as we term it in America, the word sow being seldom employed there to denote the act of depositing in the earth even the smallest seed.
The Purple Grakle travels very far north. I have found it everywhere during my peregrinations, and in one or two instances have seen it form its nest in the fissures of rocks.
