Clangula clangula americana. Lake Umbagog, Maine. 1897. literally piled one on another. They were uncovered but there May 15. was an abundance of down about them. I saw the pair (or another pair) of Whistlers flying a- long near shore this afternoon and on this, as well as every other occasion that I can remember, the duck was leading and the drake following closely in her wake. May 26. Watrous and Gilbert went up the Lake this morning. They spent the day among the stubs near the Outlet and also rowed down the river and into Sweat's Meadow. They found three Whistlers'nests, one with 8 eggs just west of Leanord's Pond, (but not in either of the stubs where we found nests last year), the other two in Sweat's Meadow. One of the latter was in the hole in the tall stub where we found an addled egg and some egg shells last year. A Whistler flew from it to-day when W. rapped on the stub. On climbing to the nest he found that it contained two eggs of the Whistler and six of the Hooded Merganser! The third nest was only about seventy-five yards from the one which contained the Merganser's eggs.
