penguins make sounds like squak
by making a wierd piercing noise to warn other penguins
yup
they get stressed out and refuse to mate (reproduce)
of course they do! but I don't know how it's sorta a bird noise :)
they devolop their own call/noise to exchange with the baby
it makes a hollow noise when you pull on it but when it is a normal piece of paper it makes a crinkly noise
Penguins have spikes in their throat, so when they catch a fish (penguins don't have teeth) it gets caught in their throat and suffocates in the penguin. Once the penguin realizes that the fish is...well....dead it makes a gulping noise and the fish goes down.
They have no common because Penguins are much smaller
a parrot makes a screech noise
my BMW does not start it just makes a click noise
It means to make a noise that a Guinea pig makes. Or even more, the noise that a pig pig makes.
