Merganser serrstor. Lake Umbagog Maine October 27, 1883. Paddled a bushed boat within easy range of a flock of a dozen of these "Sheldrake" and shot two. Had a good chance to watch them and as we followed for nearly half a mile trying to get a number together all the while within thirty yards of them. They would dive one after another in quick succession and come up in the same manner. Occasionally one would appear with a fish in his bill when all the others would make for him lashing the water with their wings. At other times they would chase one another in sport and sometimes would lash the water with their wings raising the body erect the while. As it was perfectly still they made a tremendous noise. They croaked incessantly. They seem among the noisest and merriest of Ducks. When fishing to-day they swam close in shore and kept straight on advancing rapidly not diving in one place like other Ducks. They ran on the water several rods when they rose. When swim- m-ing their necks were held straight and looking very long. They are stately water fowl. They rarely associate with other Ducks but there was a Whistler among the flock just referred to.
