Aythya collaris. Lake Umbagog, Maine. 1895. There was only one Duck on Errol Hill Pond to-day,-a young Sept. 24. male Ring-neck. It made three attempts to leave the place, rising and circling but evidently afraid to pass us as it must do to reach the at the outlet. Finally it swam past us along the opposite shore and then rising went out undisturbed. I noticed that its wing beats were more rapid than those of an other Duck found here except the Hooded maganza. When the pond it kept well out in the open water with its neck stretch= ed up to the full length most of the time.
