At New Orleans, this bird is commonly known by the name of “Dos Gris.” It arrives there in great flocks, about the first of November, and departs late in April, or in the beginning of May. On the lakes Borgne, St John, and Ponchartrain, it is very abundant, keeping in large flocks, separate from the other species. In that part of the country its food consists of small fishes, in pursuit of which it is seen constantly diving. It is caught in different sorts of nets, and easily kept in confinement, feeding greedily on Indian corn, whether entire or crushed by the millstone. In 1816, many thousands of these ducks as well as others of different species, were caught in nets by a Frenchman, who usually sent them alive to market in cages from the narrows of the Lakes, especially from those called “La pointe aux herbes,” and the “Isle aux pins.” So many of them, however, were procured by this man, that he after a while gave up sending them alive, on account of the great difficulty he encountered in procuring a sufficient number of cages for their accommodation. Although Dr RICHARDSON informs us that this species breeds “in all parts of the fur-countries, from the fiftieth parallel to their most northern limits,” I saw none of these birds during the spring and summer months which I spent on the coast of Labrador. I was equally unsuccessful in my search for it in Newfoundland. Indeed, I have never observed it eastward of the State of Massachusetts, although from thence it is more and more abundant the farther south you proceed, until you reach the tributaries of the Mississippi. Beyond the mouths of that river, these birds are rarely seen; and when I was there in April 1837, none were observed by my party or myself after we had left the south-west Pass on our way westward. In the Texas none were even heard of. From these circumstances I have inferred that, along with several other species, the Red-headed Duck reaches the Middle and Southern States by passing overland or following our great streams, such as the Ohio, Missouri, and Mississippi, westward, and the North River, and others eastward, both in its vernal and autumnal migrations. This I am the more inclined to believe, on account of the great numbers which on such occasions I have seen in ponds in the States of Illinois, Indiana, Ohio, and Kentucky.
