Though a common inhabitant of the deep and fetid morasses, where the sombre mangrove crosses its tangled roots in inextricable confusion, this fine bird is much oftener heard than seen. The superstitious negro, whose heart is in his throat if he is compelled to stir beyond his threshold by night, is often startled by the loud and hoarse _quok_ of this bird, suddenly emitted from the dark solitudes on either side of the road, or from the branches of a tree above his head, where the bird is roosting for the night. Occasionally, when out before day, seeking some birds which are to be shot only at dawn, I have myself heard the same loud cry repeated with deliberation, while the sudden flapping of large wings told that the bird, not less startled, was seeking a station less liable to interruption, farther within the morass. In floating down such broad streams as Burnt Savanna, or Black River, where they are margined by tall overhanging mangrove-woods, we often see this bird, seated on some high branch, which commands a wide prospect; but no sooner is the canoe espied, than he spreads his immense wings, and sails heavily off with the customary vociferation. Vigilant and suspicious, it is not an easy thing to shoot the Quok, unless the sportsman see it first, and conceal himself before he is discovered, or cautiously creep towards the secluded retreat where he hears the voice. But this is almost a forlorn hope; for the senses of the bird are very acute, and he takes alarm from the slight sounds made by the most circumspect footsteps, and escapes in time. Any unusual noise will provoke the utterance of the unmusical voice; a shout, or the report of a distant gun, will be answered from several parts of the morass; and not only by this species, but in various tones by other Herons and Bitterns. It is a noble bird; its commanding height, erect attitude, stout built frame, fiery eye, powerful beak, hanging crest, and handsome plumage, give it an imposing aspect. Crabs and other Crustacea form its principal diet; evidently swallowed entire, though often of considerable size. The flesh is dark; the fat, which is usually abundant, is of a deep yellow tinge. Notwithstanding the powerful voice of this bird, the trachea is weak, and destitute of convolution or enlargement, save at the divarication of the bronchi. A specimen was shot in April, in the spotted plumage, which is supposed to indicate youth. It fell into the water, wounded, where it began to swim, the head erect, and the body no more immersed than that of a duck; it struck out with both feet, and made rapid way towards the roots of a mangrove near, on reaching which it jumped out of water, and ran up, but was then secured. In this state it is sometimes called the Guinea-hen Quok, from the white spots on the grey ground; and I am not sure that it is not distinct. One that was shot in May in this plumage, a female, had eggs in the ovary as large as pepper-corns.
