The Night Heron is a constant resident in the Southern States, where it is found in abundance in the low swampy tracts near the coast, from the mouth of the Sabine river to the eastern boundaries of South Carolina. On the whole of that vast extent of country, it may be procured at all seasons. The adult birds keep farther south than the young, flocks of the latter remaining in South Carolina during the whole winter, and there the Night Herons are at that period more common than most other species of the family. In that State it is named “the Indian Pullet,” in Lower Louisiana the Creoles call it “Gros-bec,” the inhabitants of East Florida know it under the name of “Indian Hen,” and in our Eastern States its usual appellation is “Qua-bird.”

In the course of my winter rambles through East Florida, I met with several of the large places of resort of Night Herons, and, in particular, one remarkable for the vast number of birds congregated there. It is about six miles below the plantation of my friend JOHN BULOW, Esq., on a bayou which opens into the Halifax river. There several hundred pairs appeared to be already mated, although it was only the month of January; many of the nests of former years were still standing, and all appeared to live in peace and contentment. My friend JOHN BACHMAN is acquainted with a place on Ashley river, about four miles distant from Charleston, where, among the branches of a cluster of live-oak trees, he has for the last fifteen years found a flock of about fifty of these birds during the winter. They were all young, not a single individual having been observed in the adult plumage, which is the more remarkable, because it is usual for young birds to retreat farther south during winter than the old. It is very common at this period for the sportsmen near Charleston to take their stand along the margins of the salt-water ponds, to which the Herons generally resort about dusk; and they frequently obtain several shots in an evening, but not a single old bird is known to have been killed at this season.

The Night Heron seldom advances very far into the country, but remains on the low swampy lands along the coast. It is rare to see one farther up the Mississippi than the mouth of the Arkansas, to which a few are at times induced to go while rambling along the great stream. I never saw one, nor heard of any, whilst in Kentucky, and I doubt much if they are ever seen in the upper parts of the State of Tennessee. The distance of a hundred iniles from the tide-mark appears to be the farthest extent of their inland movements. On the other hand, they are fond of resorting to the islands along the coast, on many of which they breed.

At the approach of spring, great numbers of those which have wintered far south, leave their places of sojourn and migrate eastward, although probably an equal number remain in the low lands of Louisiana and the Floridas during the whole year. There, indeed, I have found them with eggs in April and May, and as young birds just fledged were very abundant at the same places, I concluded that these eggs were of the second laying. By the middle of March, the number of Night Herons is seen to increase daily in the Carolinas, and, about a month later, some make their appearance in the Middle Districts, where many remain and breed. They are not abundant in the State of New York, are seen sparingly breeding in Massachusetts, while only a few proceed to Maine, and farther eastward they are looked upon as a great curiosity. In Nova Scotia, Newfoundland, and Labrador, this species is quite unknown.

Some European writers have alleged, that the Night Heron is scarce in the United States, and of rare occurrence even in the southern parts. I wish these people had been with me and my friend BACHMAN, or with some of the many hundred persons who reside in the Southern Districts, or have travelled from Louisiana to North Carolina. How strange it would have appeared to such assertors of notions, to have seen a boat load of Night Herons shot in the course of a few hours, and that too in the winter season.

Excepting while breeding, this species is extremely shy and wary, especially the adults. To approach them from a distance after they have seen you, is no easy task. They seem to know the distance at which your gun can injure them, they watch all your movements, and at the proper moment leave their perches. Should you chance to crack a stick while advancing towards them, they start at once, give a few raps with their wings, in the manner of the Common Pigeon, and fly off as if delighted at your disappointment. On the contrary, you may shoot them with ease, if you lie in wait near the places to which they resort to roost by day, and at which they generally arrive singly, or a few at a time, when, from your place of concealment among the trees, you may kill them the moment they alight over your head, and at a short distance. In this manner I have known forty or fifty procured by two sportsmen in the course of about two hours. You may also not unfrequently shoot them at any hour of the day, by starting them from secluded feeding-grounds, and thus I have shot a good many in different parts of the United States, and even in the Middle Districts. They are, however, rarely shot whilst on the ground, their hearing being still more acute than that of the American Bittern, which prefers squatting in the grass to flying off, when any noise is heard, whereas the Night Heron rises immediately.

 This species breeds in communities around the stagnant ponds, either near rice plantations or in the interior of retired and secluded swamps, as well as on some of the sea-islands covered with evergreen trees. Their heronries are formed either in low bushes, or in middle-sized or tall trees, as seems most convenient or secure. In the Floridas, they are partial to the mangroves that overhang the salt-water; in Louisiana, they prefer the cypresses; and in the Middle States, they find the cedars most suitable. In some breeding-places within a few miles of Charleston, which I visited in company with my friend JOHN BACHMAN, the nests were placed on low bushes, and crowded together, some within a yard of the ground, others raised seven or eight feet above it, many being placed flat on the branches, while others were in the forks. Hundreds of them might be seen at once, as they were built on the side of the bushes fronting the water. Those which I found in the Floridas were all placed on the south-west sides of mangrove islands, but were farther apart from each other, some being only about a foot above high-water mark, while others were in the very tops of the trees, which, however, scarcely exceeded twenty feet in height. In some inland swamps in Louisiana, I saw them placed on the tops of tall cypress trees about a hundred feet high, and along with those of Ardea Herodias, A. alba, and some Anhingas. In the Jerseys I have found the Night Herons breeding on water-oaks and cedars; and my friend THOMAS NUTTALL informs me, that “in a very secluded and marshy island, in Fresh Pond, near Boston, there likewise exists one of these ancient heronries; and though the birds have been frequently robbed of their eggs, in great numbers, by mischievous boys, they still lay again immediately after, and usually succeed in raising a second brood.” The same accurate observer remarks, that “about the middle of October, the Qua-birds begin to retire from this part of Massachusetts, towards their southern winter quarters, although a few of the young birds still linger occasionally to the 29th or 30th of that month.” This last observation is a farther evidence of the reluctance which the young of this species feel to go as far south during winter as the old birds.

The nest of the Night Heron is large, flattish, and formed of sticks placed in different directions, sometimes to the height of three or four inches. At times it is arranged with so little care, that the young upset it before they are able to fly. Many of the nests are annually repaired, and these birds, when they have once found an agreeable settlement, return regularly to it, until some calamity forces them to abandon it. The full number of the eggs is four, and they measure at an average two inches and one-sixteenth by an inch and a half. They are thin-shelled, and of a plain light sea-green colour. In about three weeks after the young are hatched, most of them leave the nest, and crawl about the branches, to which they cling firmly, ascending to the tops of the bushes or trees, and there awaiting the return of their parents with food. If you approach them at such times, the greatest consternation ensues both among the young and the old birds; the loud and incessant croaking which both have until then kept up, suddenly ceases; the parent birds rise in the air, sail around and above you, some alighting on the neighbouring trees; while the young scramble off in all directions to avoid being taken. So great at times is their terror, that they throw themselves into the water, and swim off with considerable rapidity, until they reach the shore, when they run and hide in every convenient place. Retire for half an hour, and you will be sure to hear the old and the young calling to each other; the noise gradually increases, and in a short time is as loud as ever. The stench emitted by the excrements with which the abandoned nests, the branches and leaves of the trees and bushes, and the ground, are covered, the dead young, the rotten and broken eggs, together with putrid fish and other matters, renders a visit to these places far from pleasant. Crows, Hawks and Vultures torment the birds by day, while Racoons and other animals destroy them by night. The young are quite as good for eating as those of the Common Pigeon, being tender, juicy, and fat, with very little of the fishy taste of many birds which, like them, feed on fishes and reptiles. At this period few if any of the old birds have the long feathers of the hind head, and these are not reproduced before the latter part of the following winter, when they seem to attain their extreme length in a few weeks.

The flight of the Night Heron is steady, rather slow, and often greatly protracted. They propel themselves by regular flappings of the wings, and, like the true Herons, draw in their head on the shoulders, while their legs stretch out behind, and with the tail form a kind of rudder. When alarmed they at times rise high in the air, and sail about for awhile. They sail in the same manner before alighting on their feeding grounds, which they rarely do without having previously attended to their security by alighting on the neighbouring trees and looking about them. Their migrations are performed under night, when their passage is indicated by their loud hoarse notes, resembling the syllable qua, uttered at pretty regular intervals. On these occasions they appear to fly faster than usual.

On the ground, this bird exhibits none of the grace observed in all the true Herons; it walks in a stooping posture, the neck much retracted, until it sees its prey, when, with a sudden movement, it stretches it out and secures its food. It is never seen standing motionless, waiting for its prey, like the true Herons, but is constantly moving about in search of it. Its feeding places are the sides of ditches, meadows, the shady banks of creeks, bayous, and ponds or rivers, as well as the extensive salt-marshes and mud-bars left exposed at low water; and I have observed it to alight in the ponds in the suburbs of Charleston towards evening, and feed there. In all such situations, excepting the last, this bird may often be seen by day, but more especially in the evening or morning twilight, wading up to its ankles, or, as we commonly say, its knee-joints. Its food consists of fishes, shrimps, tadpoles, frogs, water-lizards, and leeches, small crustacea of all kinds, water insects, moths, and even mice, which seem not less welcome to it than its more ordinary articles of food. When satisfied, it retires to some high tree on the banks of a stream or in the interior of a swamp, and there it stands, usually on one leg, for hours at a time, apparently dosing, though seldom sound asleep.

When wounded, this bird first tries to make its escape by hiding among the grass or bushes, squatting the moment it finds what it deems a secure place; but if no chance of a safe retreat occurs, it raises its crest, ruffles its feathers, and, opening its bill, prepares to defend itself. It can bite pretty severely, but the injury inflicted by its bill is not to be compared with that produced by its claws, which on such occasions it uses with much effect. If you seize it, it utters a loud, rough, continued sound, and tries to make its escape whenever it perceives the least chance.
 
The Night Heron undergoes three annual changes of plumage ere it attains its perfect state, although many individuals breed in the spring of the third year. After the first autumnal moult, the young is as you see it represented in the plate. In the second autumn, the markings of the neck and other parts have almost entirely disappeared; the upper parts of the head have become of a dull blackish-green, mixing near the upper mandible with the dull brown of the first season, while the rest of the plumage has assumed a uniform dull ochreous greyish-brown. In the course of the following season, the bird exhibits the green of the shoulders and back, the head is equally richly coloured, and the frontal band between the upper mandible and the eye, and over the latter, is pure white. At this age it rarely has the slender white feathers of the hind head longer than an inch or two. The sides of the neck, and all the lower parts, have become of a purer greyish-white. The wings are now spotless in all their parts, and of a light brownish-grey, as is the tail. The following spring, the plumage is complete, and the bird is as represented in the plate. After this period, with the exception of losing its long crest-feathers after the young are hatched, it retains its colouring. No difference can be observed in the tints of the sexes, but the male is somewhat larger.

A very considerable difference in size is observable at all seasons in birds of this species. Some that are fully feathered, and therefore at least three years old, measure as much as four inches less than others of the same sex, and weigh less in proportion. These circumstances might suffice with some naturalists to attempt to form two species out of one, but in this they would certainly fail.

In the neighbourhood of New Orleans, and along the Mississippi as far up as Natchez, the shooting of this species is a favourite occupation with the planters, who represent it as equalling any other bird in the delicacy of its flesh.

The frog, of which I have introduced a figure, is common in the retired swamps which the Night Heron frequents, and is often devoured by it. The flowering plants which you see, are abundant in the States of Georgia and South Carolina, as well as in the Floridas.
