觀察細節
Odd looking yellow brown duck the same size as a Mallard, with a gray bill, and a narrow black line running down the center of the neck. The bird gave its diagnostic whistling sounds. Multiple photographs obtained, along with audio recordings. There are also Mallards and Great tailed Grackles calling in the background. Mallards and Coots keep harassing the Fulvous Whistling Duck.
