In the spring season these birds move to the northward, and make their appearance along the Atlantic coast of the continent, where they diffuse joy into the hearts of the fishermen – because the latter know, on seeing them, that they may soon expect the large shoals of herring, shad, and other fish, for which they have been anxiously looking out. So great favourites are they with the fisherman, that they would not knowingly kill an osprey for a boat-load of fish, but regard these bold fishing birds in the light of “professional brethren.” In this case the old adage that “two of a trade never agree” is clearly contradicted.
The farmer often takes up his gun to fire at the osprey – mistaking it for the red-tailed buzzard or some other hawk, several species of which at a distance it resembles – but, on discovering his mistake, brings down his piece without pulling trigger, and lets the osprey fly off unharmed. This singular conduct on the part of the farmer arises from his knowledge of the fact, that the osprey will not only not kill any of his ducks or hens, but that where he makes a settlement he will drive off from the premises all the hawks, buzzards, and kites, that would otherwise prey upon the poultry. With such protection, therefore, the osprey is one of the securest birds in America. He may breed in a tree over the farmer's or fisherman's door without the slightest danger of being disturbed in his incubation.
I say his incubation; but the male takes no part in this domestic duty, further than to supply his loved mate with plenty of fish while she does the hatching business. Of course, thus protected, the osprey is not a rare bird. On the contrary, fish-hawks are more numerous than perhaps any other species of the hawk tribe. Twenty or thirty nests may be seen near each other in the same piece of woods, and as many as three hundred have been counted on one little island. The nests are built upon large trees – not always at the tops, as those of rooks, but often in forks within twenty feet of the ground. They are composed of large sticks, with stalks of corn, weeds, pieces of wet turf, and then lined plentifully with dry sea-grass, or any other grass that may be most convenient.
The whole nest is big enough to make a load for a cart, and would be heavy enough to give any horse a good pull. It can be seen, when the woods are open, to an immense distance, and the more easily, as the tree upon which it is built is always a “dead wood,” and therefore without leaves to conceal it. Some say that the birds select a dead or decaying tree for their nest. It is more probable such is the effect and not the cause, of their building upon a particular tree. It is more likely that the tree is killed partly by the mass of rubbish thus piled upon it, and partly by the nature of the substances, such as sea-weed in the nest, the oil of the fish, the excrement of the birds themselves, and the dead fish that have been dropped about the root, and suffered to remain there; for when the osprey lets fall his finny prey, which he often does, he never condescends to pick it up again, but goes in search of another.
Boys “a-nesting” might easily discover the nest of the osprey; but were they inclined to despoil it of its three or four eggs (which are about the size of a duck's, and blotched with Spanish brown), they would find that a less easy task, for the owners would be very likely to claw their eyes out, or else scratch the tender skin from their beardless cheeks: so that boys do not often trouble the nest of the osprey.
A very curious anecdote is related of a negro having climbed up to plunder a nest of these birds. The negro's head was covered with a close nap of his own black wool, which is supposed by a certain stretch of fancy to have the peculiarity of “growing in at both ends.” The negro, having no other protection than that which his thick fur afforded him, was assailed by both the owners of the nest, one of which, making a dash at the “darkie's” head, struck his talons so firmly into the wool, that he was unable to extricate them, and there stuck fast, until the astonished plunderer had reached the foot of the tree. We shall not answer for the truthfulness of this anecdote, although there is nothing improbable about it; for certain it is that these birds defend their nests with courage and fury, and we know of more than one instance of persons being severely wounded who made the attempt to rob them.
The ospreys, as already stated, feed exclusively on fish. They are not known to prey upon birds or quadrupeds of any kind, even when deprived of their customary food, as they sometimes are for days on account of the lakes and rivers, in which they expected to find it being frozen over to a later season than usual. Other birds, as the purple grakles, often build among the sticks of the osprey's nest, and rear their young without being meddled with by this generous bird. This is an important point of difference between the osprey and other kinds of hawks; and there is a peculiarity of structure about the feet and legs of the osprey, that points to the nature of his food and his mode of procuring it. His legs are disproportionately long and strong. They are without feathers nearly to the knees. The feet and toes are also very long, and the soles are covered with thick, hard scales, like the teeth of a rasp, which enable the bird to hold securely his slippery prey. The claws, too, are long, and curved into semicircles, with points upon them almost as sharp as needles.
I have stated that an incident occurred to our party that illustrated some of the habits of this interesting bird. It was upon the afternoon of a Saturday, after they had fixed their camp to remain for the following day. They had landed upon a point or promontory that ran out into the river, and from which they commanded a view of a fine stretch of water. Near where they had placed their tent was the nest of an osprey, in the forks of a large poplar. The tree, as usual, was dead, and the young were plainly visible over the edge of the nest. They appeared to be full-grown and feathered; but it is a peculiarity of the young ospreys that they will remain in the nest, and be fed by the parent birds, until long after they might be considered able to shift for themselves. It is even asserted that the latter become impatient at length, and drive the young ones out of the nest by beating them with their wings; but that for a considerable time afterwards they continue to feed them – most likely until the young birds learn to capture their finny prey for themselves.
This Lucien gave as a popular statement, but did not vouch for its truth. It was not long, however, before both he and his companions witnessed its complete verification.
The old birds, after the arrival of the voyageurs upon the promontory, had remained for some time around the nest, and at intervals had shot down to where the party was, uttering loud screams, and making the air whizz with the strokes of their wings. Seeing that there was no intention of disturbing them, they at length desisted from these demonstrations, and sat for a good while quietly upon the edge of their nest. Then first one, and shortly after the other, flew out, and commenced sailing in circles, at the height of an hundred feet or so above the water. Nothing could be more graceful than their flight. Now they would poise themselves a moment in the air, then turn their bodies as if on a pivot, and glide off in another direction.
All these motions were carried on with the most perfect ease, and as if without the slightest aid from the wings. Again they would come to a pause, holding themselves fixed in mid-air by a gentle flapping, and appearing to scrutinise some object below. Perhaps it was a fish; but it was either too large a one, or not the species most relished, or maybe it had sunk to too great a depth to be easily taken. Again they sail around; one of them suddenly arrests its flight, and, like a stone projected from a sling, shoots down to the water. Before reaching the surface, however, the fish, whose quick eye has detected the coming enemy, has gone to the dark bottom and concealed himself; and the osprey, suddenly checking himself by his wings and the spread of his full tail, mounts again, and re-commences his curvilinear flight.
After this had gone on for some time, one of the birds – the larger one, and therefore the female – was seen to leave off hunting and return to the nest. There she sat only for a few seconds, when, to the
