Heronries are becoming more and more rare. M. Toussenet states that he has met with only one in all France, that at Ecury (Marne), between Epernay and Châlons. They are not uncommon in England, where many ancient families connect the heronry with their ancestral grandeur. Lord Warwick's heronry, on the classic Avon, still maintains seventy or eighty pairs of the noble birds.
The Grey Heron has enemies in the Eagle, the Falcon, and the Crows. The latter combine to steal its eggs; the former aim at the Heron itself, its flesh being much to their taste. When the Heron finds itself pursued by a bird of prey, it immediately disencumbers itself of all unnecessary ballast, and then endeavours to get the uppermost in flying; this plan is nearly its only means of safety. Occasionally it succeeds, for the Heron is able to attain immense altitudes. If it is close pressed, it makes an admirable use of its bill as a means of defence, and has been known to impale its adversary. Its usual tactics are, to wait for its enemy, lance in rest, and to allow the latter to pierce himself through, merely by his own impetuosity. If it has a chance to dart its bill into the eye of its foe, it does not neglect so good an opportunity of utilising its small endowments. This is, in fact, a private lunge, a coup de grâce, and many a dog, hunting among the reeds, has felt the poignancy of this offensive weapon. We must, however, allow that the Heron is not always so fortunate, and that oftener than not he becomes a prey to his eager adversaries—the Eagle and the Falcon.
The magnificent powers of flight possessed by the Heron, and his clever devices in defending himself, gave rise, in days gone by, to the very special regard with which he was honoured by kings and princes, who hunted him with Falcons trained to the sport. The poor Heron was doubtless not very gratified for these marks of high esteem, and it is probable that, if he could be consulted at the present day, he would bless the happy obscurity in which he is now allowed to vegetate. "It costs too much to shine in the world," is the moral La Fontaine puts into the mouth of his Heron.
Although its flavour is certainly as disagreeable as possible, the flesh of the Heron was in the old time reckoned as a "royal dish," and was only served upon the tables of the great and powerful of the earth. In order to procure this supposed delicacy more easily, the idea arose of artificially arranging a certain part of the forest so as to attract the unhappy birds into a retreat which should realise all the characteristics of the natural heronry. The birds here enjoyed all the comforts of life up to the moment when they were ruthlessly torn from them at the will and pleasure of their lord. We must add that they adopted the plan of taking from them their progeny to assist the royal treasury; for, as Pierre Belon tells us, "they were in the habit of trading largely in the young ones, which brought considerable sums of money." Francis I. caused heronries to be established at Fontainebleau, which, as connoisseurs tell us, were everything that could be wished.
The Heron is quite susceptible of training when it is caught young; but it must always be little else than a bird of ornament, as the service it can render amounts to little or nothing. When adult at the time of capture it is altogether intractable, entirely refusing food, and dying at the end of a few days.
The Purple Heron (Ardea purpurea) has the same habits as the one just spoken of, but it is a little smaller. It owes its name to the colour of the numerous spots which adorn its livery. It is rarely met with in France, but is pretty common at the mouths of the Danube and Volga, and on the margins of some of the lakes in Tartary.
The White Heron (Egretta alba) is remarkable for its plumage, which is entirely of a pure white. Two varieties of it are known—the larger, generally called the Great Egret, is about the size of the Ashy Heron; it is common in Eastern Europe, in the North of Africa and America, and in the Malay Archipelago. The smaller kind is known by the name of the Garzette Heron, or the Little Egret, and is no bigger than a Crow; it inhabits the confines of Asia and Eastern Europe, and regularly visits the South of France.

These two species are adorned, during the breeding season, with fine and silky feathers, which spring from the shoulders, and, spreading out over the back, fall on each side of the tail in elegant plumes. These are the feathers with which European ladies are so fond of adorning themselves, and from them the birds have derived their name.
