Vocalization
Honking: The most commonly heard vocalization of the Orinoco goose is a distinctive honking sound. The honk is a loud, resonant call that is often described as a low-pitched "honk" or "huhonk." This call is believed to serve as a means of communication between individuals, especially during flight or to establish territory boundaries.
Trumpeting: The goose also produces a characteristic trumpeting sound, which can be a series of short, sharp notes or a prolonged, melodious sound. This vocalization is often associated with courtship or territorial displays and may serve as a signal to attract mates or communicate with other geese in the vicinity.
Hissing: When threatened or alarmed, the Orinoco goose may emit a hissing noise. This sound is created by expelling air through its bill and is often accompanied by defensive posturing, such as raising the head, extending the neck, or fluffing the feathers as a warning to potential threats.
