The bird is indeed very uncommon in this country. Latham mentions one in the Leverian Museum, which was shot, not many miles from London, in May 1782.
Voracity of the Heron.—In the month of April 1818, as a person was walking a short distance from the river Mole, in the neighbourhood of Cobham Park, Surrey, where H. C. Combe, Esq. has a heronry, he was surprised by a pike in weight full 2lbs. dropping from the air immediately before him: on looking up, he perceived a large heron hovering over him, which had no doubt dropped the fish from its beak. And also, during the same month, another individual near the above spot, saw a heron take a fish from the water, and after carrying it to a bank insert its bill into the vent of the fish, beginning to suck its entrails; he drove away the bird, and on taking up the fish, found it to be a pike weighing a pound and upwards.
Some hawks will not attack a heron, when it is first shown to them; but they may generally be brought to it by flying them at a cock, of a light colour, and by tying meat upon a heron’s back, and allowing them to feed there. Small pieces of elder are put upon the heron’s beak, to prevent him from wounding the hawk in training. The herons are caught by a slip-knot at the end of a long string, so arranged round their nests as to be drawn about their legs when they come upon their eggs. This is best done about sun-set; and the man who is to draw the string, must place himself to leeward of the nest. Herons will not feed when they are first taken; it is therefore necessary to cram them with food, and to tie a piece of mat round their necks, to prevent them from throwing it up again.
A well-stocked heronry in an open country is necessary for this sport. The herons go out in the morning to rivers and ponds at a very considerable distance, in search of food, and return to the heronry towards the evening.
It is at this time that the falconers place themselves in the open country, down wind of the heronry; so that when the herons are intercepted on their return home, they are obliged to fly against the wind to gain their place of retreat. When a heron passes, a cast (a couple) of hawks is let go. The heron disgorges his food when he finds that he is pursued, and endeavours to keep above the hawks by rising in the air; the hawks fly in a spiral direction to get above the heron, and thus the three birds frequently appear to be flying in different directions. The first hawk makes his stoop as soon as he gets above the heron, who evades it by a shift, and thus gives the second hawk time to get up and to stoop in his turn. In what is deemed a good flight, this is frequently repeated, and the three birds often mount to a great height in the air. When one of the hawks seizes his prey, the other soon binds to him, as it is termed, and buoyant from the motion of their wings, the three descend together to the ground with but little velocity. The falconer must lose no time in getting hold of the heron’s neck when he is on the ground, to prevent him from injuring the hawks. It is then, and not when he is in the air, that he will use his beak in his defence. Hawks have, indeed, sometimes, but very rarely, been hurt by striking against the heron’s beak when stooping, but this has been purely by accident, and not (as has been said) by the heron’s presenting his beak to his pursuer as a means of defence.
When the heron flies down wind, he is seldom taken, the hawks are in great danger of being lost, and as the flight is in a straight line, it affords but little sport.—Bewick—Pennant—Sebright.
