Lophodytes cucullatus. 1889, October 23. Lake Umbagog. Leonard's Pond. Crossed the island and found my birds, six Hooded Mer- gansers, three of them adult males in full plumage. It was some- time before I recognized them for their kept their crests closed. They followed the opposite shore diving incessantly. I watched them over an hour but they would not cross to my side. October 24. Lake Umbagog. Rapid River. A flock of six Hooded Mergansers, three of them adult males, doubtless the same birds seen in Leonard's Pond yesterday. Had a fine chance to stalk them by crossing a narrow neck of land, but just as I felt sure of them I heard one give a warning kok followed by a rolling k-r-r-r-r. I could see a superb old drake swimming within easy range, but the bushes in the way were so dense that I dared not risk a shot. A moment later I saw the flock out in the middle of the river with necks stretched up and soon after they flew and went out over the lake. Their powers of sight and hearing must be extraordinary. The drake I saw near me had his crest fully expanded. 1890, October 16. Lake Umbagog. Bottle Brook Pond. the gleam Near the end of the point I caught ^of a white breast on an old snag, and directing my glass to the spot made out four hooded Mergansers, sitting on a log sunning themselves. There was a good chance to stalk them under cover of the bushes but they must have heard me for when I got within shot of the log and peeped over the bank they were gone and I discovered them swimming up the middle of the pond toward's M.'s station. For a long time they cruised back and forth in the open water, diving a good deal for food. 125
