Anas obscura. 2 Lake Umbagog, Maine. 1897. morning of the 22nd we saw the Duck and her mate swimming a- May 24. bout together feeding within 40 to 100 yds. of the nest. On both occasions we saw the ♀ return to it by rising and flying directly towards it, plunging into the woods only a few yards above the ground. I doubt if the ♀ ever went out of sight of the island. After photographing the nest and eggs, 6-7 A.M., May 23, I left the camera in position about 15 ft. off, partially concealing it by the trunk of a large birch and further mask- ing it and the tripod legs with young spruces. Although it stood there the whole forenoon the Duck would not return to her nest. At frequent intervals we saw her with her mate flying over and around the island, evidently alarmed or at least suspicious. She returned to her eggs soon after I remo- moved the camera at 1 P.M. Nest found May 23. Nest, 10 eggs, northern extremity of small island on west shore of Sweat Cove. Island heavily wooded with spruces, balsams, white pines and birches with the densest possible undergrowth of young spruces. The nest was about 30 ft. from the water in three directions and near the middle of a thicket of these little spruces (3 to 5 ft. high) which were so crowded together over as well as around the nest that I doubt if any large bird, even a Partridge, 35
