Nettium formosum. June 6, 1909. A friend in Stege, Contra Costa County, has Two ducks and a drake of this species. The drake does not appear to be changing in plumage yet, all three are more or less worn. November 21, 1909. My friend has one duck and one drake now; the duck was getting into fresh winter plumage and her primaries were just ap- pearing. The drake was in the eclipse plumage, although a few vermiculated flank feathers were appearing; he had new primaries fully grown. March 4, 1911. Obtained two pairs from Robison Bros. All in high plumage, although very dirty and cage-worn. One drake had several old eclipse feathers in his flanks; otherwise he was in high plumage. March 14, 1911.
