Mareca Americana July 27, 1911. The drake has taken on the eclipse plumage & a considerable extent, notably in the back, flanks, and crissum. Aug. 14, 1911. The three female Widgeon looks to be in fine fresh plumage except for lesser wing coverts. The drake looks very much like the ducks now; a few of the characteristic drake feathers of the back still remain. October 29, 1911. 2 females in fresh plumage including tails. 1 female in fresh plumage except primaries. The male is in eclipse except for ver- miculated feathers appearing in flanks and back and white feathers on sides of tump. New primaries, secondaries and tertiaries. No bald pate. No new tail or tail-coverts. I note in all the drakes that eclipse feathers show- but little wear when moulting and do not look worn out like high plumaged feathers when they are moulted. November 5, 1911. The female mentioned above is now without pri- mary; new one still in their sheaths are just appearing.
