You know how when your trying to be hush hush about something, you tell people a secret in a whisper. We seem to have great control of the volume of our voices and use it accordingly. Do other animals have this same control? I feel like dogs, horses etc might be able to but I started wondering about birds. I can’t think of a time where their chirps were any quieter than the usual loud pitch they do. Do they have the vocal ability to chirp quieter? Maybe they are able to, but have no reason to. If they do I wish they would whisper in the early mornings, rather than waking me up at the crack of dawn!
