Bucephala americana. Maine (Lake Umbagog). 1872. June 3. A nest containing four of this species and one of the Hooded Merganser was found by Gideon Stone in a stub about fifteen feet above the water. 1873. Aug. 12. Shot a young bird on Cambridge River about two miles above the dam. " 19. Shot a young bird about half grown near the mouth of Bottle Brook on the Megalloway; it was alone, and diving for food. 1876. June 3. A female shot to-day near the Outlet would have laid her first egg in a few hours. 1879. June 6. George Hayward tells me that he took a set of fif- teen eggs on May 18 last; the nest was in a dead stub about [illegible] feet above the water, the eggs nearly fresh. The female was exceedingly shy and regularly flew from the hole before he got within gunshot of the tree. He considers this species one of the shiest of the ducks when sitting. [24 Aug. 1879]. " 15. I have long known that the nests of this species often contained parasitical eggs of other Ducks, especial- ly of the Hooded Merganser. It now appears that the whistler sometimes returns the compliment, for Alva Cool- idge tells me that while collecting for Dr. Stearn's son he took a set of thirteen Duck's eggs, and six Whistlers. A female Wood Duck was sitting on these eggs. 1880. June 1. Found a nest in a natural cavity about ten feet above the water in the east side of a small ash stub, The hole descended about twelve inches. The female flew from the hole when we were about twenty yards away; her bill was wide open, but, save for the whistling of her wings, she went off in silence. The cavity contain- ed three whole eggs, from one of which a duckling was trying to escape, and three recently hatched young. There was no nest, only a little of the birds down about the eggs and young.
