Anas obscura Lake Umbagog, Maine. 1889 Maine Sept.-Oct & Umbagog - Very numerous through Sept and the first week of Oct. after which the water rose so high that most of the feeding grounds was submerged. It fell to its original level late in Oct. but the Ducks did not return. A few remained through the period of high water. They were in large flocks early in Sept. Some flocks About the 10th Stan Mann saw a flock of 150 near the Outlet. In October I killed some of the large light-colored birds Northern birds with dull coral red legs. They seemed to be tamer than the Larger gray local birds. Most of the latter were alight out in the lake unless alighting wounded but in late October we saw several small flocks of in deep water migrants come down from a great height & alight in deep water on the lake. one or twice with Scoters. The favorite food of Black Ducks at Umbagog through Food the last half of Sept. & early Oct. was the seeds of Scirpus crispus (identified by W. Dean from specimens), in fact for 3 or 4 weeks they eat practically nothing else. During this period the water was so high that they could swim about among the grass and feed on the seeds without even crossing up for them. The stomachs and crops of all the birds shot were crammed with these seeds. In this season I saw Black Ducks dive at the Wounded birds discharge of a gun as quickly as would a Scoter. On both diving occasions the bird went 30 or 40 yds. under water, came out at the edge of the grass, went ashore, & was found hiding with one wing broken. On Sept. 22 a flock of about 40 which I was watching through my glass at about 150 yds. began diving in play. One after another would thrust the Diving in water with its wings and then dive fully as quickly & play completely as a Scoter swimming several rods under water before reappearing. At one time only a few birds over above water. After doing this for several minutes 14
