Quack vs. Chirp

Most of the time that Gary is making noise, it's her "Mean Quacks" Or her "WHERE IS EVERY BODY?????" Chirps. Whenever I give her fresh water she will make her "happy chirps" anyone else who has a duck would know what the difference between the three. Whenever she's complaining about anyone she will sound like she had failed at a quack mixed with a chirp!
