Bucephala americana Lake Umbagog, Maine. 1889 Maine Oct. 16 S. Umbagog - An adult ♂ in full plumage in Sweet Meadow. I watched the adult him for some time through the glass. He was diving for plumage. food staying under about ½ minute at a time. He finally saw us and flew at fully 300 yds. going over the pond several times rising higher and higher & finally coming out directly over us at a height of about 250 ft. His wings produced the humming top whistle as distinctly as I have ever heard it on the sea coast.
