Chaulaemon streperus. Feb. 16, 1911. Received a fine high-plumaged drake Gadwall. April 16, 1911. During the past few days the drake Gadwall, No. 1, has been heard to call. The note is a rather sharp quack, more like a female Mallard's than anything else. Only one note seems to be given at a time. July 5, 1911. The drake Gadwall is getting some of the dark feathers of the eclipse plumage in his back and sides. July 27, 1911. The drake Gadwall is changing quite rapidly although the feathers of the head and neck are not moulted yet. August 1, 1911. The flanks and back are now in eclipse, while the black tail coverts are rapidly giving way to those of the eclipse plumage. October 29, 1911. Passing from eclipse to high plumage.
