观察细节
Black Scoter's very interesting repeated head-dipping behavior was seen several times while swimming and prior to an underwater dive. See Sibley: "throws head downward when exercising wings, a distinctive motion". My observations did not involve the scoter exercising wings. However, on the Black Scoter's several takeoffs, I heard shrill whistling as described also in Sibley. First time this species has been seen by me on the Herring River.
