MARMARONETTA ANGITSTIROSTRIS 247 



The voice has been variously described as a whistling croak, a low 

 croaking whistle, a rather hoarse quack, and a quack like that of 

 the domestic duck, but very harsh and abrupt. It is probable that 

 these descriptions apply to two notes, and that this duck, like some 

 others, has two distinct calls, one more or less of a whistle, the 

 other somewhat of the nature of a quack. 



It is practically omnivorous and as an article of diet itself it 

 is not first-class.
