The repetition and frequency modulation of these quacks form the auditory basis for species identification in offspring, a process known as acoustic conspecific identification. Simmons (1977) speak of "rape-intent flights". [41] Examples of this rule in birds are rare as they lack external ears, but the bill of ducks is supplied with a few blood vessels to prevent heat loss,[42] and, as in the Greenland mallard, the bill is smaller than that of birds farther south, illustrating the rule.
