Marica americana. December 10, 1911. The drake seems to be getting new tail feathers. The "bald-pate" is beginning to show a little. Black under-tail-coverts seem to be apparently fully developed. The bird looks quite shabby as though and extensive loss of feathers was taking place. December 17, 1911. Drake is a little farther along than last Sunday. Females in fine fresh feather, apparently having undergone at least a partial body moult.
