Anas obscura. Lake Umbagog, Maine. Evening flight of Ducks. 1894. Late in the afternoon a flock of eight Ducks which I took Sept.9. to be Scooters came flying up the Lake and alighted about mid- way between Pine and Moose Points. Jim and I started for them at once but they proved to be Black Ducks. They alighted, a- gain, in the river and when we reached Richardson's Carry a very large flock rose and after circling about dropped in the Lake several hundred yards out. For nearly an hour they floated and swam about on the smooth water; then they started for the shore but they did not come near us. A single bird, however, came flying in through the Carry and I dropped it into the rushes where Jim quickly found it. For the next half hour there was scarce a minute when one or more Black Ducks were not in sight. Singly, in pairs, in small bunches, or in flocks of twenty to forty they came high and low from every direction, wheeled and circled against the bright western sky and then alighted in the marsh. Such a quacking and plashing as they made! The entire marsh seemed alive with them. Yet I did not get another shot. At frequent intervals we heard the squealing cry (a murmuring whistle it may be called) of Wood Ducks and there were incessant calls from various waders among which I recognized that of the Golden Plover, Grass-bird, (T.maculata), Summer Yellow-legs, Semipalmated Sandpiper and Solitary Sandpiper.
