4. Spatula clypeata. November 21, 1909. The drake Shoveller shows no change; still retains old wing quills. December 26, 1909. The drake Shoveller moulted his wing quills some time ago. His head is beginning to show some dusky spots particularly near the base of the bill. The bill is horn color instead of black as when in high feather. Some white feathers are beginning to appear on one shoulder. January 11, 1910. The blackish spots at the base of the bill of the drake Shoveller are becoming more pronounced, and this morning I noted a blackish spot about the size of a dime on the side of the neck. January 29, 1911. The one remaining female Shoveller "Zelda" has been in fresh plumage for some time.
