L.Umbagog. Bucephala albeola 1890. Three ?? or young in Erroll Hill pond diving incessantly for Oct.25, food, sometimes close in shore sometimes out in deep water. They arched their backs and sprang nearly clear of the water, cleaving the surface almost (but not quite) as deftly as Sheldrakes. When under water their positions could be traced by the bubbles which kept coming to the surface. When the bird reappeared its buoyancy made it bob high out of the water like a cork. Two fished together diving and reappearing at about the same time. The others worked singly. All maintained perfect silence. One flew and alighted near me striking the surface with a light rustling sound and shoot- ing several yards making a silvery wake or furrow. Four in Erroll Hill Pond to-day. I watched them for about Oct.26, three hours, during which they fished uninterruptedly. Although most industrious and energetic in pursuing this occupation they seemed to be much less restless than most Ducks, confining their operations to a more limited area, and often diving for half an hour or more in practically the same spot. They were feeding (as I ascertained by shooting and dissecting two of them) on the larvae chiefly "darners"(Notonecta) and "water bugs"(Gyrinus) of aquatic insects, with which this pond literally swarms. On com- ing up from a dive each bird would usually erect its head and look keenly around for a moment but often this precaution was omitted. They paid little or no attention to noise and I found it perfectly easy to approach them within close gun range although it was im- possible to move in the woods without making a good deal of noise the ground being covered with dry leaves and dead twigs and the day perfectly still.
