Clangula clangula americana. Lake Umbagog, Maine. 1897. Whistler's head and neck appeared at the opening. The next June 2. instant she was in the air and darting off over our heads. It was all done so quickly that although I was watching the hole with the closest attention I actually did not see the bird leave it. Indeed she appeared to burst forth at nearly full speed and I was half inclined to believe that she began her flight within the trunk. I certainly did not see her open her wings. It seemed incredible that so heavy and clumsy a bird could emerge from such a place so adroitly and get under full headway so quickly. Not that this particular hole was exceptionally small. On the contrary it was of rather generous size. Its shape and position are well shown by two photographs which I took of it. I also photographed the other nest with the fresh eggs. Upon first entering the pond this morning we started four female Whistlers from somewhere near the further end. These birds kept coming back at intervals through the day circling high over the pond always keeping together and calling kur-uck kur-uck. Twice they were accompanied by a drake, a fine fellow in full plumage. June 5. A Whistler followed by 7 or 8 young about as large as Robins came through Leonard's Pond this forenoon swimming close along the shore.
