“Tts note is seldom heard by day, but while coming into the feeding- 
grounds at night with the Widgeons, Black Ducks and Mallards, the 
hoarse, muffled quack of the duck and the mellow whistle of the drake 
are heard mingled with the whistling of the Widgeon and the loud 
calls of the Black Duck. In the springtime the drake often gives utter- 
ance to low, soft: notes which seem to flow from deep down in the throat, 
especially while performing curious courting antics in the presence of 
the ducks.” (Eaton.) The Pintail’s long, slender neck, and in the male 
the long tail-feathers, are good field-marks.
