Communication/Vocalization
Giraffes are mainly quiet animals and the majority of their communication takes place on a non-verbal level. However, certain noises have been observed in the wild and captivity. The vocalization of giraffes becomes more prevalent during the mating season. The males will make what appears to be similar to a human coughing in order to attract the attention of females. When a female is making a constant low whistling sound is when she is communicating with her calf.
