The flight of this species is in strength intermediate between that of Ardea Herodias and A. rufescens, and is well sustained. On foot its movements are as graceful as those of the Louisiana Heron, its steps measured, its long neck gracefully retracted and curved, and its silky train reminded one of the flowing robes of the noble ladies of Europe. The train of this Egret, like that of other species, makes its appearance a few weeks previous to the love season, continues to grow and increase in beauty, until incubation has commenced, after which period it deteriorates, and at length disappears about the time when the young birds leave the nest, when, were it not for the difference in size, it would be difficult to distinguish them from their parents. Should you however closely examine the upper plumage of an old bird of either sex, for both possess the train, you will discover that its feathers still exist, although shortened and deprived of most of their filaments. Similar feathers are seen in all other Herons that have a largely developed train in the breeding season. Even the few plumes hanging from the hind part of the Ardea Herodias, A. Nycticorax, and A. violacea, are subject to the same rule; and it is curious to see these ornaments becoming more or less apparent, according to the latitude in which these birds breed, their growth being completed in the southern part of Florida two months sooner than in our Middle Districts.
The American Egrets leave the Floridas almost simultaneously about the 1st of March, and soon afterwards reach Georgia and South Carolina, but rarely the State of New Jersey, before the middle of May. In these parts the young are able to fly by the 1st of August. On the Mule Keys off the coast of Florida, I have found the young well grown by the 8th of May; but in South Carolina they are rarely hatched until toward the end of that month or the beginning of June. In these more southern parts two broods are often raised in a season, but in the Jerseys there is, I believe, never more than one. While travelling, early in spring, between Savannah in Georgia and Charleston in South Carolina, I saw many of these Egrets on the large rice plantations, and felt some surprise at finding them much wilder at that period of their migrations than after they have settled in some locality for the purpose of breeding. I have supposed this to be caused by the change of their thoughts on such occasions, and am of opinion that birds of all kinds become more careless of themselves. As the strength of their attachment toward their mates or progeny increases through the process of time, as is the case with the better part of our own species, lovers and parents performing acts of heroism, which individuals having no such attachment to each other would never dare to contemplate. In these birds the impulse of affection is so great, that when they have young they allow themselves to be approached, so as often to fall victims to the rapacity of man, who, boasting of reason and benevolence, ought at such a time to respect their devotion.
The American Egrets are much attached to their roosting places, to which they remove from their feeding grounds regularly about an hour before the last glimpse of day; and I cannot help expressing my disbelief in the vulgar notion of birds of this family usually feeding by night, as I have never observed them so doing even in countries where they were most abundant. Before sunset the Egrets and other Herons (excepting perhaps the Bitterns and Night Herons) leave their feeding grounds in small flocks, often composed of only a single family, and proceed on wing in the most direct course, at a moderate height, to some secure retreat more or less distant, according to the danger they may have to guard against. Flock after flock may be seen repairing from all quarters to these places of repose, which one may readily discover by observing their course.
Approach and watch them. Some hundreds have reached the well-known rendezvous. After a few gratulations you see them lower their bodies on the stems of the trees or bushes on which they have alighted, fold their necks, place their heads beneath the scapular feathers, and adjust themselves for repose. Daylight returns, and they are all in motion. The arrangement of their attire is not more neglected by them than by the most fashionable fops, but they spend less time at the toilet. Their rough notes are uttered more loudly than in the evening, and after a very short lapse of time they spread their snowy pinions, and move in different directions, to search for fiddlers, fish, insects of all sorts, small quadrupeds or birds, snails, and reptiles, all of which form the food of this species.
The nest of the Great White Egret, whether placed in a cypress one hundred and thirty feet high, or on a mangrove not six feet above the water, whether in one of those dismal swamps swarming with loathsome reptiles, or by the margin of the clear blue waters that bathe the Keys of Florida, is large, flat, and composed of sticks, often so loosely put together as to make you wonder how it can hold, besides itself, the three young ones which this species and all the larger Herons have at a brood. In a few instances only have I found it compactly built, it being the first nest formed by its owners. It almost always overhangs the water, and is resorted to and repaired year after year by the same pair. The eggs, which are never more than three, measure two inches and a quarter in length, an inch and five-eighths in breadth, and when newly laid are smooth, and of a pale blue colour, but afterwards become roughish and faded. When the nest is placed on a tall tree, the young remain in it, or on its borders, until they are able to fly; but when on a low tree or bush, they leave it much sooner, being capable of moving along the branches without fear of being injured by falling, and knowing that should they slip into the water they can easily extricate themselves by striking with their legs until they reach either the shore or the nearest bush, by clinging to the stem, of which they soon ascend to the top.
This Egret is shy and vigilant at all times, seldom allowing a person to come near unless during the breeding season. If in a rice-field of some extent, and at some distance from its margins, where cover can be obtained, you need not attempt to approach it; but if you are intent on procuring it, make for some tree, and desire your friend to start the bird. If you are well concealed, you may almost depend on obtaining one in a few minutes, for the Egrets will perhaps alight within twenty yards or less of you. Once, when I was very desirous of making a new drawing of this bird, my friend John Bachman followed this method, and between us we carried home several superb specimens.
The long plumes of this bird being in request for ornamental purposes, they are shot in great numbers while sitting on their eggs, or soon after the appearance of the young. I know a person who, on offering a double-barrelled gun to a gentlemen near Charleston, for one hundred White Herons fresh killed, received that number and more the next day.
The Great Egret breeds in company with the Anhinga, the Great Blue Heron, and other birds of this family. The Turkey Buzzards and the Crows commit dreadful havoc among its young, as well as those of the other species. My friend John Bachman gives me the following account of his visit to one of its breeding places, at the “Round O,” a plantation about forty miles from Charleston: “Our company was composed of Benjamin Logan, S. Lee, and Dr Martin. We were desirous of obtaining some of the Herons as specimens for stuffing, and the ladies were anxious to procure many of their primary feathers for the purpose of making fans. The trees were high, from a hundred to a hundred and thirty feet, and our shot was not of the right size; but we commenced firing at the birds, and soon discovered that we had a prospect of success. Each man took his tree, and loaded and fired as fast as he could. Many of the birds lodged on the highest branches of the cypresses, others fell into the nest, and, in most cases, when shot from a limb, where they had been sitting, they clung to it for some time before they would let go. One thing surprised me: it was the length of time it took for a bird to fall from the place where it was shot, and it fell with a loud noise into the water. Many wounded birds fell some distance off, and we could not conveniently follow them on account of the heavy wading through the place. We brought home with us forty-six of the large White Herons, and three of the great Blues. Many more might have been killed, but we became tired of shooting them.”
