In addition to their use as weapons, both sexes of the Rodrigues solitaire also used their wings for communication. The wings could create low-frequency sounds for communicating with mates, or to warn rivals, but it is unknown exactly how this sound was created. The sound could be heard 200 yards (182 m) away, and this may therefore be the size of the territory of an individual. Other species of birds (e.g., club-winged manakin) are also known to use their wings to create sounds that attract mates or mark their territory.
