Mareca americana. April 7, 1911 One of the females obtained from Mr. Beck on February 16 has gotten a good many dark feathers in its breast. It is the old faded out bird. The feathers of the full plumage seem to be on the increase in the drake. The crissum is spotted with black feathers. April 13, 1911. All four of the Widgeon continue to get new feathers. The drake is improving continually and I noted that he is getting new white feathers on his side just ahead of the base of the tail. The very shabby female (or young male) which I got from Beck has gotten lots of new feathers which show particularly on the back, flanks, and breast. Both the drake and another female are getting new- tail feathers. The new feathers (on the flanks and breast, particularly the former, in the females have lighter-colored edges to the tips than the remainder of the feather. April 16, 1911. The drake appears to have chosen a mate, the other two females remaining aloof. The drake has a plaintive whistling note re- ssembling somewhat the notes of the...cock California Quail. Zirs are given in rather quick succession. April 23, 1911. Same remarks apply as made on April 13 and 16.
