Oidemia americana. 1889, Lake Umbagog. October 3. (2) were going through a motion which seems to be peculiar to Scoters if not to the single species, O.americana. This motion is difficult to describe. The bird seems to raise the entire for- ward half of his body out of the water and lengthening his neck stretches it straight upward, presenting nearly the appearance of a bottle floating with its neck upright. He then shortens his neck and sinks back into the water. The wings are not opened. The action takes only a fraction of a second. October 19. Lake Umbagog. Off B Brook Cove. We finally paddled to the latter (O.americana) near Metalluc Id. and I stopped seven with four barrels (of my two guns) getting all after reshooting two or three. Six of the seven were young birds. There was not a black male in the whole flock. October 21. Lake Umbagog. Glaspy Cove. In the Cove two Scoters apparently feeding close to the marsh. One dove. I shot the other and found it to be a young Butter-bill apparently not a wounded bird. 1890, Lake Umbagog. October 21. B Brook Cove. We next tried the large flock of Butter-bills and got within good shot of them. They rose and flew across our bows when I shot down five with the first barrel and three with the second, getting all but one of the total eight. Four were killed outright. 65
