THE REPUBLICAN OR CLIFF SWALLOW.
[Cliff Swallow.]
Genus
HIRUNDO FULVA, Vieill.
[Hirundo pyrrhonota.]

In the spring of 1815, I for the first time saw a few individuals of this species at Henderson, on the banks of the Ohio, a hundred and twenty miles below the Falls of that river.

It was an excessively cold morning, and nearly all were killed by the severity of the weather. I drew up a description at the time, naming the species Hirundo republicans, the Republican Swallow, in allusion to the mode in which the individuals belonging to it associate, for the purpose of forming their nests and rearing their young. Unfortunately, through the carelessness of my assistant, the specimens were lost, and I despaired for years of meeting with others.

In the year 1819, my hopes were revived by Mr. ROBERT BEST, curator of the Western Museum at Cincinnati, who informed me that a strange species of bird had made its appearance in the neighbourhood, building nests in clusters, affixed to the walls. In consequence of this information, I immediately crossed the Ohio to Newport, in Kentucky, where he had seen many nests the preceding season; and no sooner were we landed than the chirruping of my long-lost little strangers saluted my ear. Numbers of them were busily engaged in repairing the damage done to their nests by the storms of the preceding winter.

Major OLDHAM of the United States Army, then commandant of the garrison, politely offered us the means of examining the settlement of these birds, attached to the walls of the building under his charge. He informed us, that, in 1815, he first saw a few of them working against the wall of the house, immediately under the eaves and cornice; that their work was carried on rapidly and peaceably, and that as soon as the young were able to travel, they all departed. Since that period, they had returned every spring, and then amounted to several hundreds. They usually appeared about the 10th of April, and immediately began their work, which was at that moment, it being then the 20th of that month, going on in a regular manner, against the walls of the arsenal. They had about fifty nests quite finished, and others in progress.

About day-break they flew down to the shore of the river, one hundred yards distant, for the muddy sand, of which the nests were constructed, and worked with great assiduity until near the middle of the day, as if aware that the heat of the sun was necessary to dry and harden their moist tenements. They then ceased from labour for a few hours, amused themselves by performing aerial evolutions, courted and caressed their mates with much affection, and snapped at flies and other insects on the wing. They often examined their nests to see if they were sufficiently dry, and as soon as these appeared to have acquired the requisite firmness, they renewed their labours. Until the females began to sit, they all roosted in the hollow limbs of the sycamores (Platanus occidentalis) growing on the banks of the Licking river, but when incubation commenced, the males alone resorted to the trees. A second party arrived, and were so hard pressed for time, that they betook themselves to the holes in the wall, where bricks had been left out for the scaffolding. These they fitted with projecting necks, similar to those of the complete nests of the others. Their eggs were deposited on a few bits of straw, and great caution was necessary in attempting to procure them, as the slightest touch crumbled their frail tenement into dust. By means of a table-spoon, I was enabled to procure many of them. Each nest contained four eggs, which were white, with dusky spots. Only one brood is raised in a season. The energy with which they defended their nests was truly astonishing. Although I had taken the precaution to visit them at sun-set, when I supposed they would all have been at rest, yet a single female happening to give the alarm, immediately called. out the whole tribe. They snapped at my hat, body and legs, passed between me and the nests, within an inch of my face, twittering their rage and sorrow. They continued their attacks as I descended, and accompanied me for some distance. Their note may be perfectly imitated by rubbing a cork damped with spirit against the neck of a bottle.

A third party arrived a few days after, and immediately commenced building. In one week they had completed their operations, and at the end of that time thirty nests hung clustered like so many gourds, each having a neck two inches long. On the 27th July, the young were able to follow their parents. They all exhibited the white frontlet, and were scarcely distinguishable in any part of their plumage from the old birds. On the 1st of August, they all assembled near their nests, mounted some three hundred feet in the air, and about 10 o’clock in the morning took their departure, flying in a loose body, in a direction due north. They returned the same evening about dusk, and continued these excursions, no doubt to exercise their powers, until the third, when, uttering a farewell cry, they shaped the same course at the same hour, and finally disappeared. Shortly after their departure, I was informed that several hundreds of their nests were attached to the court-house at the mouth of the Kentucky river. They had commenced building them in 1815. A person likewise informed me, that, along the cliffs of the Kentucky, he had seen many bunches, as he termed them, of these nests attached to the naked shelving rocks overhanging that river.

Being extremely desirous of settling the long-agitated question respecting the migration or supposed torpidity of Swallows, I embraced every opportunity of examining their habits, carefully noted their arrival and disappearance, and recorded every fact connected with their history. After some years of constant observation and reflection, I remarked that among all the species of migratory birds, those that remove farthest from us, depart sooner than those which retire only to the confines of the United States; and, by a parity of reasoning, those that remain later return earlier in the spring. These remarks were confirmed as I advanced towards the south-west, on the approach of winter, for I there found numbers of Warblers, Thrushes, &c. in full feather and song. It was also remarked that the Hirundo viridis of WILSON (called by the French of Lower Louisiana Le Petit Martinet a ventre blanc) remained about the city of New Orleans later than any other Swallow. As immense numbers of them were seen during the month of November, I kept a diary of the temperature from the 3d of that month, until the arrival of Hirundo purpurea. The following notes are taken from my journal, and as I had excellent opportunities, during a residence of many years in that country, of visiting the lakes to which these Swallows were said to resort, during the transient frosts, I present them with confidence.

Nov. 11.–Weather very sharp, with a heavy white frost. Swallows in abundance during the whole day. On inquiring of the inhabitants if this was a usual occurrence, I was answered in the affirmative by all the French and Spaniards. From this date to the 22nd, the thermometer averaged 65 degrees, the weather generally a drizzly fog. Swallows playing over the city in thousands.

Nov. 25.–Thermometer this morning at 30 degrees. Ice in New Orleans a quarter of an inch thick. The Swallows resorted to the lee of the Cypress Swamp in the rear of the city. Thousands were flying in different flocks. Fourteen were killed at a single shot, all in perfect plumage, and very fat. The markets were abundantly supplied with these tender, juicy, and delicious birds. Saw Swallows every day, but remarked them more plentiful the stronger the breeze blew from the sea.

Jan. 14.–Thermometer 42 degrees. Weather continues drizzly. My little favourites constantly in view.

Jan. 28.–Thermometer at 40 degrees. Having seen the Hirundo viridis continually, and the H. purpurea or Purple Martin beginning to appear, I discontinued my observations.

During the whole winter many of them retired to the holes about the houses, but the greater number resorted to the lakes, and spent the night among the branches of Myrica cerifera, the Cirier, as it is termed by the French settlers.

About sunset they began to flock together, calling to each other for that purpose, and in a short time presented the appearance of clouds moving towards the lakes, or the mouth of the Mississippi, as the weather and wind suited. Their aerial evolutions before they alight, are truly beautiful. They appear at first as if reconnoitering the place; when, suddenly throwing themselves into a vortex of apparent confusion, they descend spirally with astonishing quickness, and very much resemble a trombe or water-spout. When within a few feet of the ciriers, they disperse in all directions, and settle in a few moments. Their twittering, and the motions of their wings, are, however, heard during the whole night. As soon as the day begins to dawn, they rise, flying low over the lakes, almost touching the water for some time, and then rising, gradually move off in search of food, separating in different directions. The hunters who resort to these places destroy great numbers of them, by knocking them down with light paddles, used in propelling their canoes.

THE BARN SWALLOW.
[Barn Swallow.]
Genus
HIRUNDO RUSTICA, Linn.
[Hirundo rustica.]

The Barn Swallow makes its first appearance at New Orleans from the middle of February to the first of March. They do not arrive in flocks, but apparently in pairs, or a few together, and immediately resort to the places where they have bred before, or where they have been reared. Their progress over the Union depends much on the state of the weather; and I have observed a difference of a whole month, owing to the varying temperature, in their arrival at different places. Thus in Kentucky, Virginia, or Pennsylvania, they now and then do not arrive until the middle of April or the beginning of May. In milder seasons they reach Massachusetts and the eastern parts of Maine by the 10th of the latter month, when you may rest assured that they are distributed over all the intermediate districts. So hardy does this species seem to be, that I observed it near Eastport in Maine, on the 7th May, 1833, in company with the Republican or Cliff Swallow, pursuing its different avocations, while masses of ice hung from every cliff, and the weather felt cold to me. I saw them in the Gut of Cansso on the 10th of June, and on the Magdeleine Islands on the 13th of the same month. They were occupied in building their nests in the open cupola of a church. Not one, however, was observed in Labrador, although many Sand Martins were seen there. On our return, I found at Newfoundland some of the present species, and of the Cliff Swallow, all of which were migrating southward on the 14th of August, when Fahrenheit’s thermometer stood at 41 degrees.

In spring, the Barn Swallow is welcomed by all, for she seldom appears before the final melting of the snows and the commencement of mild weather, and is looked upon as the harbinger of summer. As she never commits depredations on any thing that men consider as their own, every body loves her, and, as the child was taught by his parents, so the man teaches his offspring, to cherish her. About a week after the arrival of this species, and when it has already resorted to its wonted haunts, examined its last year’s tenement, or made choice of a place to which it may securely fix its nest, it begins either to build or to deposit its eggs.

The nest is attached to the side of a beam or rafter in a barn or shed, under a bridge, or sometimes even in an old well, or in a sink hole, such as those found in the Kentucky barrens. Whenever the situation is convenient and affords sufficient room, you find several nests together, and in some instances I have seen seven or eight within a few inches of each other; nay, in some large barns I have counted forty, fifty, or more. The male and the female both betake themselves to the borders of creeks, rivers, ponds, or lakes, where they form small pellets of mud or moist earth, which they carry in their bill to the chosen spot, and place against the wood, the wall, or the rock, as it may chance to be. They dispose of these pellets in regular lays, mixing, especially with the lower, a considerable quantity of long slender grasses, which often dangle for several inches beneath the bottom of the nest. The first layers are short, but the rest gradually increase in length, as the birds proceed upwards with their work, until they reach the top, when the fabric resembles the section of an inverted cone, the length being eight inches, and the greatest diameter six, while that from the wall or other flat surface to the outside of the shell is three and a half, and the latter is fully an inch thick. I have never observed in a newly finished nest, the expansion of the upper layer mentioned by WILSON, although I have frequently seen it in one that has been repaired or enlarged. The average weight of such a nest as I have described is more than two pounds, but there is considerable difference as to size between different nests, some being shorter by two or three inches, and proportionally narrow at the top. These differences depend much on the time the birds have to construct their tenement previous to depositing the eggs. Now and then I have seen some formed at a late period, that were altogether destitute of the intermixture of grass with the mud observed in the nest described above, which was a perfect one, and had occupied the birds seven days in constructing it, during which period they laboured from sunrise until dusk, with an intermission of several hours in the middle of the day. Within the shell of mud is a bed, several inches thick, of slender grasses arranged in a circular form, over which is placed a quantity of large soft feathers. I never saw one of these nests in a chimney, nor have I ever heard of their occurring in such situations, they being usually occupied by the American Swift, which is a more powerful bird, and may perhaps prevent the Barn Swallow from entering. The eggs are from four to six, rather small and elongated, semi-translucent, white, and sparingly spotted all over with reddish-brown. The period of incubation is thirteen days, and both sexes sit, although not for the same length of time, the female performing the greater part of the task. Each provides the other with food on this occasion, and both rest at night beside each other in the nest. In South Carolina, where a few breed, the nest is formed in the beginning of April, and in Kentucky about the first of May.

When the young have attained a considerable size, the parents, who feed them with much care and affection, roost in the nearest convenient place. This species seldom raises more than two broods in the Southern and Middle Districts, and never, I believe, more than one in Maine and farther north. The little ones, when fully fledged, are enticed to fly by their parents, who, shortly after their first essays, lead them to the sides of fields, roads or rivers, where you may see them alight, often not far from each other, on low walls, fence-stakes and twigs, or the withered twigs or branches of some convenient tree, generally in the vicinity of a place in which the old birds can easily procure food for them. As the young improve in flying, they are often fed on the wing by the parent birds. On such occasions, when the old and young birds meet, they both rise obliquely in the air, and come close together, when the food is delivered in a moment, and they separate to continue their gambols. In the evening the family retires to the breeding place, to which it usually resorts until the period of their migration.

About the middle of August, the old and young birds form more extensive associations, flying about in loose flocks, which are continually increasing, and alighting in groups on tall trees, churches, court-houses, or barns, where they may be seen for hours pluming and dressing themselves, or removing the small insects which usually infest them. At such times they chirp almost continually, and make sallies of a few hundred yards, returning to the same place. These meetings and rambles often occupy a fortnight, but generally by the 10th of September great flocks have set out for the south, while others are seen arriving from the north. The dawn of a fair morning is the time usually chosen by these birds for their general departure, which I have no reason to believe is prevented by a contrary wind. They are seen moving off without rising far above the tops of the trees or towns over which they pass; and I am of opinion that most of them in large parties usually migrate either along the shores of the Atlantic, or along the course of large streams, such places being most likely to afford suitable retreats at night, when they betake themselves to the reeds and other tall grasses, if it is convenient to do so, although I have witnessed their migration during a fine, clear, quiet evening. Should they meet with a suitable spot, they alight close together, and for awhile twitter loudly, as if to invite approaching flocks or stragglers to join them. In such places I have seen great flocks of this species in East Florida;–and here, reader, I may tell you that the fogs of that latitude seem not unfrequently to bewilder their whole phalanx. One morning, whilst on board the United States Schooner “Spark,” lieutenant commandant PIERCY and the officers directed my attention to some immense flocks of these birds flying only a few feet above the water for nearly an hour, and moving round the vessel as if completely lost. But when the morning is clear, these Swallows rise in a spiral manner from the reeds to the height of thirty or forty yards, extend their ranks, and continue their course.

I found flocks of Barn Swallows near St. Augustine for several days in succession, until the beginning of December; but after the first frost none were to be seen. These could not have removed many decrees farther south, for want of proper food, and I suspect that numbers of them spend the whole winter along the south coast of the Gulf of Mexico.

The flight of this species is not less interesting than any other of its characteristics. It probably surpasses in speed that of any other species of the feathered tribes, excepting the Humming-bird. In fine calm weather their circuits are performed at a considerable elevation, with a lightness and ease that are truly admirable. They play over the river, the field, or the city with equal grace, and during spring and summer you might imagine their object was to fill the air around them with their cheerful twitterings. When the weather lowers, they move more swiftly in tortuous meanderings over the meadows, and through the streets of the towns; they pass and repass, now close to the pavement, now along the walls of the buildings, here and there snapping an insect as they glide along with a motion so rapid that you can scarcely follow them with the eye. But try:–There she skims against the wind over the ruffled stream; up she shoots, seizes an insect, and wheeling round, sails down the breeze with a rapidity that carries her out of your sight almost in a moment. Noon arrives, and the weather being sultry, round the horse or the cow she passes a thousand times, seizing on each tormenting fly. Now she seems fain to enter the wood, so close along its edge does she pursue her prey; but spying a Crow, a Raven, a Hawk or an Eagle, off she shoots with redoubled speed after the marauder, and the next instant is seen lambing, as it were, the object of her anger with admirable dexterity, after which, full of gaiety and pride, the tiny thing returns towards the earth, forming to herself a most tortuous path in the air.

On the ground the movements of this Swallow are by no means awkward, although, when compared with those of other birds, they seem rather hampered. It walks by very short steps, and aids itself with its wings. Should it be necessary to remove to the distance of a few yards, it prefers flying. When alighted on a twig, it shews a peculiar tremulous motion of the wings and tail.

The song of our Barn Swallow resembles that of the Chimney Swallow of England so much that I am unable to discern the smallest difference. Both sing on the wing and when alighted, and the common tweet which they utter when flying off is precisely the same in both. Their food also is similar; at least that of our bird consists entirely of insects, some being small coleoptera, the crustaceous parts of which are disgorged in roundish pellets scarcely the size of a small pea.

I have represented a pair of our Barn Swallows in the most perfect spring plumage, together with a nest taken from one of the rafters of a barn in the State of New Jersey, in which there was at least a score of them.

An individual of this species preserved in spirits measured to end of tail 6 8/12 inches, to end of wings 6 2/12; wing from flexure 4 10/12; tail 3 1/4; extent of wings 12 9/12. The roof of the mouth is flat and somewhat transparent; the posterior aperture of the nares oblongo-linear, margined with strong papillae; the tongue 3 1/4 twelfths long, triangular, emarginate and papillate at the base, thin, the tip slit and lacerate. The mouth is supplied with numerous mucous crypts; its width is 5 1/2 twelfths. There is a very narrow flattened salivary gland, similar to that of the Purple Martin, but proportionally smaller. The oesophagus is 2 inches long, 1 1/2 twelfths in width, simple or without dilatation. The stomach is elliptical, 7 1/2 twelfths long, 6 twelfths broad, its muscles distinct; the epithelium, as in the other species, tough, with longitudinal rugae, and of a reddish-brown colour. The intestine is short and wide, its length being 6 1/2 inches, its breadth from 2 1/2 twelfths to 2 twelfths. The coeca are 2 twelfths long, twelfth wide, and placed at the distance of 11 twelfths from the extremity; the rectum is dilated into an oblong cloaca; about 5 twelfths in width.

The trachea is 1 inch 5 twelfths long, moderately flattened, from 1 twelfth to 3/4 twelfth in breadth; its rings pretty firm, 50 in number, with two dimidiate rings. The muscles are as in the other species; the bronchi are moderate, of about 15 half rings.

VIOLET-GREEN SWALLOW.
[Violet-green Swallow.]
Genus
HIRUNDO THALASSINA, Swains.
[Tachycineta thalassina.]

Of this, the most beautiful Swallow hitherto discovered within the limits of the United States, the following account has been transmitted to me by my friend Mr. NUTTALL. “We first met with this elegant species within the table-land of the Rocky Mountains, and they were particularly abundant around our encampment on Harris Fork, a branch of the Colorado of the west. They are nearly always associated with the Cliff Swallow, here likewise particularly numerous. Their flight and habits are also similar but their twitter is different, and not much unlike the note of our Barn Swallow. In the Rocky Mountains, near our camp, we observed them to go in and out of deserted nests of the Cliff Swallows, which they appeared to occupy in place of building nests of their own. We saw this species afterwards flying familiarly about in the vicinity of a farm-house (M. LE BOUTE’s) on an elevated small isolated prairie on the banks of the Wahlamet; and as there are no cliffs in the vicinity, they probably here breed in trees, as I observed the White-bellied Martin do. This beautiful species in all probability extends its limits from hence to the table-land of Mexico, where Mr. BULLOCK, it seems, found it.

Mr. TOWNSEND, who afterwards had better opportunities of observing the habits of this bird, thus speaks of it:–“Aguila chin chin of the Chinook Indians, inhabits the neighbourhood of the Colorado of the west, and breeds alone, its margins on bluffs of clay, where it attaches a nest formed of mud and grasses resembling in some measure that of the Cliff Swallow, but wanting the pendulous neck in that of the latter species. The eggs are four, of a dark clay colour, with a few spots of reddish-brown at the larger end. This species is also found abundant on the lower waters of the Columbia river, where it breeds in hollow trees.”

Mr. TOWNSEND also informs me that in the neighbourhood of the Columbia river, the Cliff Swallow attaches its nest to the trunks of trees, making it of the same form and materials as elsewhere. From the above facts, and many equally curious, which I have mentioned, respecting the variations exhibited by birds in the manner of forming their nests, as well as in their size, materials, and situation, it will be seen that differences of this kind are not of so much importance as has hitherto been supposed, in establishing distinctions between species supposed by some to be different, and by others identical. To give you some definite idea of what I would here impress upon your mind, I need only say that I have seen nests of the Barn or Chimney Swallow placed within buildings, under cattle-sheds, against the sides of wells, and in chimneys; that while some were not more than three inches deep, others measured nearly nine; while in some there was scarcely any grass, in others it formed nearly half of their bulk. I have also observed some nests of the Cliff Swallow in which the eggs had been deposited before the pendent neck was added, and which remained so until the birds had reared their brood, amidst other nests furnished with a neck, which was much longer in some than in others. From this I have inferred that nests are formed more or less completely, in many instances, in accordance with the necessity under which the bird may be of depositing its eggs.

BANK SWALLOW OR SAND MARTIN.
[Bank Swallow.]
Genus
HIRUNDO RIPARIA, Linn.
[Riparia riparia.]

Imagine, reader, how delighted I was when, in East Florida, in the winter of 1831, I found thousands of Bank Swallows gaily skimming over the waters, and along the shores of the rivers and inlets. So numerous indeed were they that I felt inclined to think that the greater part of those which are in summer dispersed over the United States, and the regions still farther north, must have congregated to form those vast swarms. The first time I saw them was before sunrise, when I stood by the side of Lieutenant PERCY of our Navy, on the deck of the United States’ schooner the Spark, then at anchor opposite St. Augustine. The weather though warm, was thick and drizzly, so that we could not see to a great distance; but as probably some hundreds of thousands passed close to the vessel, in long and rather close flocks, I was well enabled to assure myself that the birds were of this species. On expressing my surprise and delight at beholding so vast a concourse, Lieutenant PERCY assured me, that he had seen them on all the streams which he had visited south of where we then were. The weather cleared up in a few hours, the sun shone brightly, and the little creatures were seen all around, dipping into the water to wash themselves, gambolling close over its surface, and busily engaged in procuring insects, which in that country are always abundant. In the course of the same season I also observed a good number of our Green-backed and Barn Swallows–but few compared with what are seen about New Orleans.

We can thus account for the early appearance of the Bank Swallows in our Middle Districts. That species always arrives there sooner than the rest, sometimes preceding them by a fortnight, and keeping equally in advance as far northward as its range extends. The Green-backed Swallow, Hirundo bicolor, follows closely after it; then the Purple Martin, Hirundo purpurea; after which are seen the Barn Swallow, Hirundo rustica, and lastly, on our eastern Atlantic coasts, the American Swift, Cypselus Americanus. It is probable that these species extend their autumnal migrations southward in a degree proportionate to the lateness of their appearance in sprint I have likewise observed the arrival of the Bank Swallows on the waters of the Serpentine river and those of the Regent’s Park, in London, to be in the same proportion earlier than that of the other species which visit England in spring, and have thought that, as with us, the first mentioned species retire to a less distance in winter than the rest.

The Bank Swallow has been observed on both sides of North America, and in all intermediate places suited to its habits. This is easily accounted for, when we reflect how easy it is for these birds to follow our great water-courses to their very sources. Even the ponds and lakes of our vast forests are at times visited by them; but no person seems to have been aware of the existence of two species of Bank Swallows in our country, which, however, I shall presently shew to be the case.

Wherever, throughout the United States, sand-banks or artificial excavations occur, there is found the Bank Swallow during the breeding season, in greater or smaller numbers, according to the advantages presented by the different localities, not only along the shores of our rivers and lakes, but also on the coasts of the Atlantic, and not unfrequently in inland situations, at some distance from any water. High banks, composed of softish sandy earth, on the shores of rivers, lakes, or other waters, suit them best, and in such situations their colonies are far more numerous than elsewhere. The banks of the Ohio, and some parts of those of the Mississippi, called “Bluffs,” have appeared to me to be most resorted to by this species in our western and southern districts, although I have met with considerable numbers in every State of the Union.

In Louisiana this species begins to breed early in March, and generally rears two, sometimes three broods in a season. In our Middle Districts it commences about a month later, or about the period at which it lays in Kentucky, and there produces two broods. In Newfoundland and Labrador, it rarely begins to breed before the beginning of June, and lays only once. Dr. RICHARDSON states, that he saw “thousands of these Swallows near the mouth of the Mackenzie, in the sixty-eighth parallel, on the 4th of July,” and from the state of the weather at that period supposed that they had arrived there at least a fortnight prior to that date, but no specimens were brought to England, and the description given in the Fauna Boreali-Americana is a mere transcript of that which in itself is quite imperfect. Indeed, there is not in any work with which I am acquainted an account of the Sand Swallow sufficiently minute and accurate to characterize in an adequate manner that very common species.

The sociability and gentleness of these birds, the lightness and vigour with which they perform their various evolutions, the low and unobtrusive twittering of their voice, in short, all their actions and economy, are delightful to contemplate. Their flight is exceedingly graceful, light, yet firm, and capable of great continuance. They seem indeed as if created for the purpose of spending their time on wing, for they alight less often to rest when full grown than any other of our species, when not sitting on their eggs, and are seen abroad searching for food later in the dusk, retiring for the night as late, I think, as our Swift, Cypselus Americanus. As they procure their food more commonly than the other species along the margins or over the surface of pools, lakes, rivers, or even the sea, their flight is generally performed at a small elevation, which is the case with others only when the wind blows smartly, or the atmosphere is damp and chill. The movements of their wings are those common to the family of Swallows, which flap these members less frequently than perhaps any other small land birds. The wings act on the hinge formed by the carpal joint, opening and closing like the blades of scissors. Their sailings, though frequent, are not extensive, and their tail appears to be of great service to them, as you observe that on the least deviation from a straight course, it becomes suddenly more or less closed or inclined upward, downward, or sideways; and when you see some hundreds of pairs about their breeding places, passing, repassing, and crossing each other in various ways, you almost wonder that they never come into collision with each other. The slightest movement in any direction seems sufficient to enable them to overtake and secure their prey; and they less frequently than any other species follow an insect upward to any great distance. Like all other Swallows, they drink and bathe on wing.

Their migrations are performed by day, although perhaps continued by night, and their movements are more desultory and rather slower than those of other Swallows. It is rare to observe them in great flocks at that time, their associations not being apparently formed until they reach the countries in which they spend the winter months. Their flight, when they are thus travelling, is continued rather low over the land or the water; and as in America they retire to a less distance southward than our other Swallows, they are not unfrequently seen to linger behind the rest. In South Carolina, indeed, I have seen some in November.

In summer and autumn they roost in the holes excavated for their nests; but in winter, at least in the Floridas, they always repose at night among the tall grass of the salt marshes, making choice of situations sheltered by the winds and not liable to be overflowed. At this time they keep together in large bodies while searching for food. I have several times accidentally crossed their roosting places, which I at once recognised by the quantity of their dung attached to the blades, and lying on the ground, and from which I infer that they rest clinging to the plants.

At the first appearance of spring they leave their winter quarters in pairs, or singly, or in very small flocks; but they follow each other so closely in this manner as to form an almost continued line of march. I had the pleasure of observing this to be the case with the Barn Swallow also, whilst I was proceeding toward the Texas, when that species was advancing in a contrary direction.

Although small, the Sand Swallow is a rather hardy bird; for I observed that the transient cold weather that at times occurs in the Floridas at night, seldom forces them to remove farther south. On one occasion, however, when the ice was about the thickness of a dollar, many were found dead along the shores, as well as floating on the water, whilst the rest appeared in great perturbation, wending their way in a hurried manner toward the warmer parts of the country, and taking advantage of every spot that afforded them more warmth, such as the borders of woods, and high banks of streams. I am, however, of opinion that the inclemency of the weather at times proves to be the greatest evil these birds have to encounter, especially when in early spring they are moving northward, and occasionally meet with a sudden change from temperate to cold. Even in the places selected for their summer residence, great numbers die in their holes, and many have been found there in a state bordering on torpidity.

Their food, which consists of small insects, principally of the hymenopterous kind, even during winter in the Floridas, is procured on wing. They very seldom approach walls or the trunks of trees to seize them, but frequently snatch them from the tops of grasses or other plants on which they have alighted. They also seize small aquatic insects; but, although I suspect that they disgorge in pellets the harder parts of these, I have no proof, obtained from actual observation, that they do so.

The holes perforated by this species for the purpose of breeding require considerable exertion and labour. They are usually bored at the distance of two or three feet from the summit of the bank or surface of the ground, to the depth of about three feet, but sometimes to that of four or even five. They are near each other or remote, according to the Dumber of pairs of Swallows that resort to that place, and the extent of the bank. In one situation you may find not more than a dozen pairs at work, while in another several hundreds of holes may be seen scattered over some hundreds of yards. On the bluffs of the Ohio and the Mississippi there are many very extensive breeding-places. While engaged in digging a sand-bank on the shores of the Ohio, at Henderson, for the purpose of erecting a steam-mill, I was both amused and vexed by the pertinacity with which the little winged labourers continued to bore holes day after day, whilst the pickaxes and shovels demolished them in succession. The birds seemed to have formed a strong attachment to the place, perhaps on account of the fine texture of the soil, as I observed many who had begun holes a few hundred yards off abandon them, and join those engaged in the newly opened excavation. Whether the holes are frequently bored horizontally or not I cannot say, cut many which I examined differed in this respect from those described by authors, for on introducing a gun-rod or other straight stick, I found them to have an inclination of about ten degrees upwards. The end of the hole is enlarged in the form of an oven, for the reception of the nest, and the accommodation of the parents and their brood.

When the birds have for awhile examined the nature of the bank, they begin their work by alighting against it, securing themselves by the claws, and spreading their tails considerably, so as, by being pressed against the surface, to support the body. The bill is now employed in picking the soil, until a space large enough to admit the body of the bird is formed, when the feet and claws are also used in scratching out the sand. I have thought that the slight ascent of the burrow contributed considerably to enable the bird to perform the severe task of disposing of the loose materials, which are seen dropping out at irregular intervals. Both sexes work alternately, in the same manner as Woodpeckers; and few ornithological occupations have proved more pleasing to me than that of watching several hundred pairs of these winged artificers all busily and equally engaged, some in digging the burrows, others in obtaining food, which they would now and then bring in their bills for the use of their mates, or in procuring bits of dry grass or large feathers of the duck or goose, for the construction of their nests.

So industrious are the little creatures that I have known a hole dug to the depth of three feet four inches, and the nest finished, in four days, the first egg being deposited on the morning of the fifth. It sometimes happens that soon after the excavation has been commenced, some obstruction presents itself, defying the utmost exertions of the birds; in which case they abandon the spot, and begin elsewhere in the neighbourhood. If these obstructions occur and are pretty general, the colony leave the place; and it is very seldom that, after such an occurrence, any Swallows of this species are seen near it. I have sometimes been surprised to see them bore in extremely loose sand. On the sea-coast, where soft banks are frequent, you might suppose that, as the burrows are only a few inches apart, the sand might fall in so as to obstruct the holes and suffocate their inmates; but I have not met with an instance of such a calamitous occurrence. Along the banks of small rivulets, I have found these birds having nests within a foot or two of the water having been bored among the roots of some large trees, where I thought they were exposed to mice, rats, or other small predaceous animals. The nest is generally formed of some short bits of dry grass, and lined with a considerable number of large feathers. They lay from five to seven eggs for the first brood, fewer for the next. They are of an ovate, somewhat pointed form, pure white, eight-twelfths of an inch long, and six-twelfths in breadth.

The young, as soon as they are able to move with case, often crawl to the entrance of the hole, to wait the return of their parents with food. On such occasions they are often closely watched by the smaller Hawks, as well as the common Crows, which seize and devour them, in spite of the clamour of the old birds. These depredations upon the young are in fact continued after they have left the nest, and while they are perched on the dry twigs of the low trees in the neighbourhood, until they are perfectly able to maintain themselves on wing without the assistance of their parents.

In Louisiana, or in any district where this species raises more than one brood in the season, the males, I believe, take the principal charge of the young that have left the nest, though both sexes alternately incubate, all their moments being thus rendered full of care and anxiety respecting both their offspring and the sitting bird. The young acquire the full brown plumage of the adult by the first spring, when there is no observable difference between them; but I am induced to think that they keep apart from the old birds during the first winter, when I have thought I could yet perceive an inferiority in their flight, as well as in the loudness of their notes.

This species has no song, properly so called, but merely a twitter of short lisping notes. In autumn it at times alights on trees preparatory to its departure. On such occasions the individuals, often collected in great numbers, take up the time chiefly in pluming themselves, in which occupation they continue for hours.

I must conclude with assuring you that in my opinion, no difference whatever exists between the Bank Swallow of America and that of Europe. The birds from which I made the drawing for my plate were procured on the banks of the Schuylkill river in 1824.

ROUGH-WINGED SWALLOW.
[Rough-winged Swallow.]
Genus
HIRUNDO SERRIPENNIS, Aud.
[Stelgidopteryx ruficollis.]

On the afternoon of the 20th of October, 1819, I was walking along the shores of a forest-margined lake, a few miles from Bayou Sara, in pursuit of some Ibises, when I observed a flock of small Swallows bearing so great a resemblance to our common Sand Martin, that I at first paid little attention to them. The Ibises proving too wild to be approached, I relinquished the pursuit, and being fatigued by a long day’s exertion, I leaned against a tree, and gazed on the Swallows, wishing that I could travel with as much ease and rapidity as they, and thus return to my family as readily as they could to their winter quarters. How it happened I cannot now recollect, but I thought of shooting some of them, perhaps to see how expert I might prove on other occasions. Off went a shot, and down came one of the birds, which my do, brought to me between his lips. Another, a third, a fourth, and at last a fifth were procured. The ever-continuing desire of comparing one bird with another led me to take them up. I thought them rather large, and therefore placed them in my bag, and proceeded slowly towards the plantation of WILLIAM PERRY, Esq., with whom I had for a time taken up my residence.

The bill and feet of the Swallows were pure black, and both, I thought, were larger than in the Sand Martin; but differences like these I seldom hold in much estimation, well knowing from long experience, that individuals of any species may vary in these respects. I was more startled when I saw not a vestige of the short feathers usually found near the junction of the hind toe with the tarsus in the common species, and equally so when I observed that the bird in my hand had a nearly even tail, with broad rounded feathers, the outer destitute of the narrow margin of white. At this time my observations went no farther.

I perhaps should never have discovered the differences existing between these species had I not been spurred by the remarks of VIEILLOT, who, in expressing his doubts as to their identity, and perhaps holding in his hand the bird here described, says that the tarsus is much larger than in the European Sand Martin. I have been surprised that these doubts did not awaken in others a desire to inquire into the subject. Had this been done, however, I should probably have lost an opportunity of adding another new species to those to whose nomination I can lay claim, not to speak of such as, although well known to me previous to their having been published by others, I have lost the right of naming because I had unparted my knowledge of them to those who were more anxious of obtaining this sort of celebrity. I have now in my possession one pair of these Swallows procured by myself in South Carolina during my last visit to that State. Of their peculiar habits I can say nothing; but, owing to their being less frequent than the Sand Martin, I am inclined to believe that their most habitual residence may prove to be far to the westward, perhaps in the valleys of the Columbia river.
