Family	THE ARCTIC TERN. [Arctic Tern.]
Genus	STERNA ARCTICA, Temm. [Sterna paradisaea.]

Light as a sylph, the Arctic Tern dances through the air above and around you. The graces, one might imagine, had taught it to perform those beautiful gambols which you see it display the moment you approach the spot which it has chosen for its nest. Over many a league of ocean has it passed, regardless of the dangers and difficulties that might deter a more considerate traveller. Now over some solitary green isle, a creek or an extensive bay, it sweeps, now over the expanse of the boundless sea; at length it has reached the distant regions of the north, and amidst the floating icebergs stoops to pick up a shrimp. It betakes itself to the borders of a lonely sand-bank, or a low rocky island; there side by side the males and the females alight, and congratulate each other on the happy termination of their long journey. Little care is required to form a cradle for their progeny; in a short time the variegated eggs are deposited, the little Terns soon burst the shell, and in a few days hobble towards the edge of the water, as if to save their fond parents trouble; feathers now sprout on their wings, and gradually invest their whole body; the young birds at length rise on wing, and follow their friends to sea. But now the brief summer of the north is ended, dark clouds obscure the sun, a snow-storm advances from the polar lands, and before it skim the buoyant Terns, rejoicing at the prospect of returning to the southern regions.

The day after our arrival at the Magdalene Islands, the weather was beautiful, although a stiff breeze blew from the south-west. I landed with my party at an early hour, and we felt as if at a half-way house on our journey from Nova Scotia to Labrador. Some of us ascended the more elevated parts of those interesting islands, while others walked along the shores. A clean sand-beach lay before us, and we proceeded over it, until having reached a kind of peninsula, we were brought to a stand. The Piping Plover ran and flew swiftly before us, emitting its soft and mellow notes, while some dozens of Arctic Terns were plunging into the waters, capturing a tiny fish or shrimp at every dash. Until that moment this Tern had not been familiar to me, and as I admired its easy and graceful motions, I felt agitated with a desire to possess it. Our guns were accordingly charged with mustard-seed shot, and one after another you might have seen the gentle birds come whirling down upon the waters. But previous to this I had marked their mode of flight, their manner of procuring their prey, and their notes, that I might be able to finish the picture from life. Alas, poor things! how well do I remember the pain it gave me, to be thus obliged to pass and execute sentence upon them. At that very moment I thought of those long-past times, when individuals of my own species were similarly treated; but I excused myself with the plea of necessity, as I recharged my double gun. As soon as a sufficient number of males and females lay dead at our feet, we retired from the water's edge, to watch the motions of the survivors, among whom confusion and dismay prevailed, as they dashed close over our heads, and vociferated their maledictions. We did not, however, depart until we had tried a curious experiment for the third time. A female had been shot, and lay dead on the water for a considerable while. Her mate, whom I was unwilling to destroy, alighted upon her, and attempted to caress her, as if she had been alive. The same circumstance took place three different times, on our throwing the dead bird on the water. Something of the same nature I have related in my article on the Wild Turkey. All this happened in the month of June 1833, when none of the Arctic Terns had yet produced eggs, although we found them nearly ready to lay, as were the Piping Plovers.

Our schooner now sailed onward, and carried us to the dreary shores of Labrador. There, after some search, we met with a great flock of Arctic Terns breeding on a small island slightly elevated above the sea. Myriads of these birds were there sitting on their eggs. The individuals were older than those which we had seen on the Magdalene Islands; for the more advanced in life the individuals of any species are, the more anxious are they to reproduce, the sooner do they proceed to their summer residence, and the more extensive is the range of their migration northward. On the other hand, the younger the bird is, the farther south it removes during winter, both because it thus enjoys a milder climate, and requires less exertion in procuring its food; whereas the older individuals not only have a stronger constitution, but are more expert in discovering and securing their prey, so that it is not necessary for them to extend their journey so far.

The Arctic Tern is found with us on the eastern coasts of the United States only, where it appears, from the shores of New Jersey northwards, in autumn, and whence it departs in early spring. No sooner have the winter tempests subsided, than it is observed gliding along the coast, together with many other birds. In the beginning of March, you see it following the sinuosities of the shores, some passing directly from the Sable Islands off the Bay of Fundy and Newfoundland into Baffin's Bay; others, younger, and unwilling to encounter the perils of a more extended flight, passing up the Gulf of St. Lawrence, either through the Straits of Cansso, or the broader channel between Cape Breton and Newfoundland, and betaking themselves to the Magdalene Islands and the coasts of Labrador.

While at American Harbour in June 1833, my son and some of his companions met with a low rocky island, on which hundreds of these Terns had deposited their eggs. No other species was seen there; the birds were mostly sitting, and, on the landing of the party, they all rose as if in the greatest consternation, hovered over their heads, and left their eggs to the mercy of the intruders, who carried off a basketful of them, with a few of the birds themselves.

On the 18th of the same month, the Arctic Terns were found breeding on another island in considerable numbers; many dozens of their eggs were gathered, and delicious food indeed they proved to be. The full number of their eggs is three, but as it was early in the season many had only two. Their average dimensions were an inch and a quarter in length, and five-eighths in their greatest breadth; they were oval, but rather sharp at the smaller ends; their ground-colour a light olive, irregularly covered with patches of dark umber, larger towards the round end. They were deposited on the rocks wherever there was any grass, but no nest had been formed for their reception. They differed extremely in their colour, indeed quite as much as those of the Sandwich Tern. As we approached the little island, they all rose in the air, and flew high over our heads, screaming loudly, which they continued to do until we left the place. Several were shot, and as each fell the rest immediately plunged through the air after it. Whenever one was wounded so slightly as to be able to make off, it was lost to us, and the rest followed it. Only a very few of those which we saw and shot had the bill entirely red, and those which had were evidently older birds. Some exhibited a considerable portion of the point tinged with brownish-black, yet all of them could easily be distinguished from the Sterna Hirundo, first by their smaller size, shorter tarsi, more delicate bill, and greater curvature of the outer part of their wings; and secondly, by the leaden tint of their lower parts, from the neck to the tail, those parts in Sterno Hirundo being pure white. The back is also of a deeper blue in the Arctic Tern. The long tail-feathers were much shorter in the females than in the males, but M. TEMMINCK is wrong in saying that this bird has the tail proportionally longer than that of other species, the Roseate Tern having it of much greater length, considering its diminutive size.

At the beginning of the first autumn, the plumage of the young so much resembles that of the young of Sterna Hirundo, that a person, not paying attention to the tarsi and feet, might readily confound them together. Yet even at this early age, there are strong indications of the bluish tint on the under parts. The longest tail-feathers at this period do not extend more than two inches beyond the rest; the upper parts of the body are mottled with brown, as in all the other species, and in Gulls. The mantle of this, as of all other Terns, assumes its permanent hue before any part of the wings. On the 5th of August, in Labrador, the young birds were gambolling along with their parents, over the shores of Bras d'Or Harbour, and when we left that country the Terns still remained, so that I am unable to state at what particular period they commence their journey southward.

The notes of this species resemble the syllables creek, creek, and are often repeated while the bird is on wing. During autumn it follows the sinuosities of the shores of the bays and inlets, ascending against the ebb, and returning to meet the tide, which enables it to procure its food in succession while it keeps on its course. I have only farther to mention a curious fact, which is, that all the Terns which breed in the northern parts of the United States, and in regions still nearer the pole, sit closely on their eggs, while the small species that breed to the southward incubate only during night, or in rainy weather.
