Aix sponsa. Maine (Lake Umbagog). 1907. May 23. Set B-7, Fresh. Nest in hollow red maple. The entrance hole was a long wide slit, much larger than that of any duck's nest that I have ever previously found. It was not over five feet above the water and as the hollow descended nearly two foot the bottom was very nearly down to high water mark. The eggs were laid on rotton wood but, as usual, were carefully covered with down, and when I looked in I could only see one of them. The female was swimming among the drift wood within fif- ty yards of the spot but the eggs were cold. We started a male about a hundred yards from his mate. He flew a few rods and rising rapidly alighted on a horizontal branch of a birch stub where he sat for some time watch- (May 23) ing our motions. The locality was a small flooded meadow opening in from the Androscoggin River about fif- ty yards below the mouth of the Megalloway. 1880. June 1. A female with young in the first bond below the Lake House. This is the first brood of young ducks seen here this year. 1902, Oct. 8-22 One seen in Cambridge River October 10.
