The gentleman above mentioned informed me that the old birds keep the young in the ponds until they are quite able to fly, or until the end of August, when the flocks remove on wing to the sea, and soon after leave the coast, seldom reappearing before the first days of May, or about two weeks before most other kinds of ducks. The little ones which I procured, were as you see them represented in my plate. Those that were larger were of the same colour, and none shewed any feathers on their bodies. Now and then, like all other young ducks, they would skim over the surface of the water with astonishing rapidity, emitting a sharp note somewhat resembling the syllables _pee_, _pee_, _pee_, and would then dive with the quickness of thought. When squatted among the moss, they allowed me to take them without making any attempt to escape. The young were put in a tub, and had some soaked biscuit placed near them; but they were all found dead the next morning. The range of this noisy, lively, and beautiful duck, extends along our coast as far south as Texas, and it is also found at the mouth of the Columbia River; but the species is never found on any of our fresh-water courses, and I am quite confident that Mr SAY mistook for it the Pintail Duck, _Anas acuta_, when he says that he found it on the waters of the Missouri. During all my residence in the neighbourhood of the Mississippi, and in the course of all my journeys on and along its waters, I never saw one of these birds, or heard of any having occurred on that stream above its confluence with the Gulf of Mexico; whereas the Pintails are extremely abundant there, as well as on the Missouri, the Ohio, and all our western streams, in spring and autumn. Few Long-tailed Ducks are to be seen in the market of New Orleans, and in fact they are altogether what our gunners usually call “sea ducks.”
