Bittern.
The bittern is a singular bird both in shape and habits. Take a heron and shorten its legs, neck, and beak, and thicken it generally, and then deepen its plumage to a partridge-like brown, and you will have a pretty good idea of the bittern. At one time it was common enough in England, but the spread of cultivation, the drainage of the marshes, and the pursuit of the collector have rendered it rare; and while at some seasons it is pretty common all over the country where there are places fit for its breeding-ground, in other years scarcely a specimen can be seen, and its nest is now but rarely found. Its curious note has often puzzled the country people. It has been said to put its head under water or into a hollow reed, and then to blow, and so make a noise something like that produced by the famous blowing stone in the Vale of the White Horse.
The fact, however, appears to be that the noise is produced in the usual manner, and Morris says that the bittern "commonly booms when soaring high in the air with a spiral flight."
When suddenly surprised, its flight is more like that of a carrion crow when shot at in the air. If wounded, the bittern can defend itself remarkably well, turning itself on its back, and fighting with beak and claws. It cannot run well among the reeds, so when surprised it takes refuge in flight, although it is not by any means a good flier; and as the reeds grow too closely together for it to use its wings among them, it clambers up them with its feet, until it can make play with its wings. It is essentially nocturnal in its habits, hiding close among the reeds and flags by day.
Leaving Hoveton Broad, the boys sailed quietly down the river to Ranworth Broad, without adventure. They turned from the river along the dyke which led to the broad, and with their usual enterprise they tried to take a short cut through a thin corner of reeds growing in about two feet of water, which alone divided them from the broad. They stuck fast, of course; but their usual good fortune attended them, and turned their misfortune into a source of profit. A bird like a landrail, but smaller, flew from a thick clump of vegetation near them.
"Hallo, that is not a corn-crake, is it?" said Dick.
"No, but it is a water-crake, or water-rail rather, and I expect its nest is in that clump," said Frank, and his shoes and stockings were off in a moment, and he was wading to the place whence the bird had flown.
"Yes, here it is, and there are eight eggs in it, very like a landrail's, but much lighter in colour and a little smaller. I say, if we hadn't seen the bird fly away we should never have found the nest, it is so carefully hidden. I shall take four eggs. They are not sat upon, and she will lay some more until she makes up her full number, so it is not a robbery."
