Do penguins make noise ?
Yes, and lots of it ! Pass your mouse over the first few pictures above to hear them. They have a very loud voice similar to a donkey braying. Those calls are essential since they recognize themselves only through voice, not visually. They call to attract mates, when doing courtship, when greeting a returning mate, when threatening other penguins (or a human coming too close), or sometimes when bored alone. Different species of penguins have different calls, and in some species like the Emperors the male and female have a distinct voice that one can tell apart with a little training (listen to the samples below).
