Aix sponsa. Lake Umbagog, Maine. Aix sponsa 1844 Sept 25: Shot a young bird in Bath Brook pond & moved its head to move forward & back as it swam very like a fish. The note of alarm or suspicion is a-eele. It saw me but I stood perfectly still & presently, it resumed feeding & came towards me. Lake Umbagog, Maine. Aix sponsa 1844 Sept. 13 Found five Wood Ducks in C. Pond, one group of three, one of two. The former were all drakes adults, or at least, in full plumage. I shot two of them. One was in perfect dress the other was thinly feathered about the neck. Of the two others, one was certainly a ♂, the other looked like a young & still in the brown plumage. Had a good chance to watch these ducks. They fed among the lily pads from which they picked something very few seconds; they swam away rapidly & in irregular zigzag courses often doubling & going over the same ground. The floated high & their necks were 74
