Nettium formosum. Drake. Obtained January 1, 1912. March 10, 1912. Has apparently ceased moulting and is evidently now in high plumage. The buff feathers of head still have black tips and the feathers of the crown seem to have brownish or rufous tips. At a distance the black tips do not show on the buff of the head. Perhaps these tips will be lost by wear. April 7, 1912. Aside from wear there seems to be no change. May 2, 1912. This morning I found this bird dead in the pond. Upon skinning the bird I could find no apparent cause for its death, as it seemed in perfect condition. It was no fatter than wild birds of other species which I have skinned. Bill black; iris brown. A.A.S. No. 18729. As a rule the drake of this species carries the head close to the shoulders, giving it a very round appearance. When speaking to the female in a low cluck, the bill is inclined up- wards a little. In giving the long call which re- sembles a small section of a turkey gobbler, the head is lifted straight up and the bill opened wide, the bird having the appearance of belching.
