Merganser americanus.
1907,
August 5
Lake Umbagog.
  In a sheltered cove behind B Point (opp. Lakeside) I
came suddenly on a brood of 6 young Sheldrake and their mother,
this afternoon. Although about half grown and already partly
feathered they took at once to the shore which was here rather
steep and densely covered with bushes. I ran the canoe in and
waited. In about five minutes two of the young birds emerged from
under some driftwood lodged among the bushes and running quite
nimbly to the water entered it and swam out into the lake,diving
at intervals. The other four with their mother must have crossed
the wooded point for ten minutes later the entire brood and their
parent appeared together swimming out in deep water. The old bird
croaked, but the young made no sound.
