Hence, I presume, that, like many other varieties of birds, the Bittern adapts his habits, even of nidification, to the purposes of the case, and that where no trees are to be found, in which he can breed, he makes the best he can of it, and builds on the ground; but it is my opinion that his more usual and preferred situation for his nest is in high trees, as is the case with his congeners, the Green Bittern, the blue heron, the beautiful white egret, the night heron, which may be all found breeding together in hundreds among the red cedars on the sea beach of Cape May. The nest, which I found in Maine, was built of sticks, precisely similar to that of the herons. The Bittern is a more nocturnal bird than the heron, and is never seen, like him, standing motionless as a gray stone, with his long slender neck recurved, his javelin-like bill poised for the stroke, and his keen eye piercing the transparent water in search of the passing fry. All day he rambles about among the tall grass and reeds of the marshes, sometimes pouncing on an unfortunate frog, a garter-snake, or a mouse, for, like the blue heron, he is a clever and indefatigable mouser; but when the evening comes, he bestirs himself, spreads his broad vans, rises in air, summoning up his comrades by his hoarse clang, and wings his way over the dim morasses, to the banks of some neighboring rivulet or pool, where he watches, erect sentinel, for the passing fish, shiners, small eels, or any of the lesser tribes of the cyprinidæ, and whom he detects, wo-betide; for the stroke of his sharp-pointed bill, dealt with Parthian velocity and certitude by the long arrowy neck, is sure death to the unfortunate. Mr. Giraud, in his excellent book on the birds of Long Island, thus speaks of the American Bittern, and that so truthfully and agreeably withal, that I make no apology for quoting his words at length.
