Anas obscura. Lake Umbagog, Maine. 1896. I saw to-day between the mouth of the Cambridge and the Aug.10. Mill, eight Black Ducks and as many more Whistlers. Seven of the Black Ducks were young birds about three fourths grown and unable to fly. They were veidently all of one brood but their parent did not seem to be with them. At least they all seemed to be of the same size and when I pressed them they went ashore on the river bank and took to the grass, but instead of stopping and hiding there as I expected, they crossed the land and when I showed myself above the bank began running and flapping off over the flooded meadow on the other side. 1897. May 23. Watrous found another Black's nest to-day (among some young spruces he says) on a small island on the west shore of the Sweat Cove. He nearly trod on the sitting bird who scut- tled off to the water's edge before taking wing. He mistook her at first for a Rabbit. This nest had 10 eggs. 1897. May 24. I took my camera and photographed the Black Duck's nest found by Watrous yesterday. The light was exceptionally clear and good and, as afterwards turned out, I secured some fine negatives.
