Editing Ruddy duck (section)

== Vocalizations ==
Both male and female ruddy ducks are not known to be very vocal most of the year, though they do become more vocal when courting and raising young.<ref name=":3" /> Males are known to produce short "aa-anh" calls and other noises in short bursts. Female ruddy ducks have a much higher pitched call, often having a "raanh" sound when communicating with their brood, squeaks when chased by males, and hisses and nasal sounds towards intruders.<ref name=":0" />
