Before proceeding to the description of these birds it is well to observe that it will be found the better way, in approaching them, as indeed _all_ wild fowl, to work, if possible, up wind to them; not that wild fowl have the power, as some pretend, of scenting the odor of the human enemy on the tainted gale, as is undoubtedly the case with deer and many other quadrupeds, but that their hearing is exceedingly acute, and that their heads are pricked up to listen, at the occurrence of the least unusual sound, and at the next moment—_hey, presto!_—they are off. The little cut at the head of this paper, for his spirited and faithful execution of which the author and artist must be permitted to return his acknowledgments to his friend, Mr. Brightly, represents a favorite feeding ground of the various tribes of water fowl, as is indicated by the large gaggle of geese passing over, from right to left, and the trip of green-wings alighting to the call of a clamorous drake in the background. On a rocky spur of the shore, in the right foreground, is a male Green-Winged Teal, in the act of springing, with his legs already gathered under him; and, still nearer to the front of the picture, on the right, a Blue-Winged Drake, swimming on the limpid water, soliciting his congener, with reverted neck, and the harsh gabble—whence his name—to take wing and greet the new-comers—it being the object of the draftsman to give an idea not merely of the markings and form of these two most beautiful and graceful of the duck tribe, but of their motions, the character of their flights, and the nature of their feeding grounds and habitations. The head of the Green-Winged Teal is of moderate size and compressed; the bill nearly as long as the head, deeper than broad at the base, depressed at the tip; neck slender, of moderate length; body full and depressed; wings rather small, feet short and rather far back.
