Rambles of a Naturalist

About the years 1800-1-2-3-4, the crows were so vastly accumulated and destructive in the State of Maryland, that the government, to hasten their diminution, received their heads in payment of taxes, at the price of three cents each. The store-keepers bought them of the boys and shooters, who had no taxes to pay, at a rather lower rate, or exchanged powder and shot for them. This measure caused a great havoc to be kept up among them, and in a few years so much diminished the grievance, that the price was withdrawn. Two modes of shooting them in considerable numbers were followed, and with great success: the one, that of killing them while on the wing towards the roost; and the other, attacking them in the night, when they have been for some hours asleep. I have already mentioned the regularity with which vast flocks move from various quarters of the country to their roosting-places every afternoon, and the uniformity of the route they pursue. In cold weather, when all the small bodies of water are frozen, and they are obliged to protract their flight towards the bays or sea, their return is a work of considerable labour, especially should a strong wind blow against them: at this season, also, being rather poorly fed, they are of necessity less vigorous. Should the wind be adverse, they fly as near the earth as possible, and of this the shooters, at the time I allude to, took advantage. A large number would collect on such an afternoon, and station themselves close along the foot-way of a high bank, over which the crows were in the habit of flying; and as they were in a great degree screened from sight as the flock flew over, keeping as low as possible, because of the wind, their shots were generally very effectual. The stronger was the wind, the greater was their success. The crows that were not injured found it very difficult to rise, and those that diverged laterally only came nearer to gunners stationed in expectation of such movements. The flocks were several hours in passing over; and as there was generally a considerable interval between each company of considerable size, the last arrived, unsuspicious of what had been going on, and the shooters had time to recharge their arms. But the grand harvest of crow heads was derived from the invasion of their dormitories, which are well worthy a particular description, and should be visited by every one who wishes to form a proper idea of the number of these birds that may be accumulated in a single district. The roost is most commonly the densest pine-thicket that can be found, generally at no great distance from some river, bay, or other sheet of water, which is the last to freeze, or rarely is altogether frozen. To such a roost the crows, which are, during the day-time, scattered over perhaps more than a hundred miles of circumference, wing their way every afternoon, and arrive shortly after sunset. Endless columns pour in from various quarters, and as they arrive pitch upon their accustomed perches, crowding closely together for the benefit of the warmth and the shelter afforded by the thick foliage of the pine. The trees are literally bent by their weight, and the ground is covered for many feet in depth by their dung, which, by its gradual fermentation, must also tend to increase the warmth of the roost. Such roosts are known to be thus occupied for years, beyond the memory of individuals; and I know of one or two which the oldest residents in the quarter state to have been known to their grandfathers, and probably had been resorted to by the crows during several ages previous. There is one of great age and magnificent extent in the vicinity of Rock Creek, an arm of the Patapsco. They are sufficiently numerous on the rivers opening into the Chesapeake, and are everywhere similar in their general aspect. Wilson has signalised such a roost at no great distance from Bristol, Pa.; and I know by observation that not less than a million of crows sleep there nightly during the winter season.

To gather crow heads from the roost, a very large party was made up, proportioned to the extent of surface occupied by the dormitory. Armed with double-barrelled and duck guns, which threw a large charge of shot, the company was divided into small parties, and these took stations, selected during the day-time, so as to surround the roost as nearly as possible. A dark night was always preferred, as the crows could not, when alarmed, fly far, and the attack was delayed until full midnight. All being at their posts, the firing was commenced by those who were most advantageously posted, and followed up successively by the others, as the affrighted crows sought refuge in their vicinity. On every side the carnage then raged fiercely, and there can scarcely be conceived a more forcible idea of the horrors of a battle, than such a scene afforded. The crows screaming with fright and the pain of wounds; the loud deep roar produced by the raising of their whole number in the air; the incessant flashing and thundering of the guns; and the shouts of their eager destroyers, all produced an effect which can never be forgotten by any one who has witnessed it, nor can it well be adequately comprehended by those who have not. Blinded by the blaze of the powder, and bewildered by the thicker darkness that ensues, the crows rise and settle again at a short distance, without being able to withdraw from the field of danger, and the sanguinary work is continued until the shooters are fatigued, or the approach of day-light gives the survivors a chance of escape. Then the work of collecting the heads from the dead and wounded began, and this was a task of considerable difficulty, as the wounded used their utmost efforts to conceal and defend themselves. The bill and half the front of the skull were cut off together, and strung in sums for the tax-gatherer, and the product of the night divided according to the nature of the party formed. Sometimes the great mass of shooters were hired for the night, and received no share of scalps, having their ammunition provided by the employers: other parties were formed of friends and neighbours, who clubbed for the ammunition, and shared equally in the result.

During hard winters the crows suffer greatly, and perish in considerable numbers from hunger. When starved severely, the poor wretches will swallow bits of leather, rope, rags, in short, anything that appears to promise the slightest relief. Multitudes belonging to the Bristol roost perished during the winter of 1828-9 from this cause. All the water-courses were solidly frozen, and it was distressing to observe these starvelings every morning winging their weary way towards the shores of the sea, in hopes of food, and again toiling homewards in the afternoon, apparently scarce able to fly.

In speaking of destroying crows, we have never adverted to the use of poison, which in their case is wholly inadmissible, on this account – where crows are common, hogs generally run at large, and to poison the crows would equally poison them: the crows would die, and fall to the ground, where they would certainly be eaten by the hogs.

Crows, when caught young, learn to talk plainly, if pains be taken to repeat certain phrases to them, and they become exceedingly impudent and troublesome. Like all of their tribe, they will steal and hide silver or other bright objects, of which they can make no possible use.
