..have bladders.

No other birds have bladders 'cos if you fly you don't want to carry a bottle of heavy liquid around. But if you don't..... God is damn clever. So what about emus?

From what I can find, ostriches and emu do not have bladders, although there do seem to be some folks online saying that they do.

Not a subject that I have ever cared about, but what is your point?


Under a government which imprisons any unjustly, the true place for a just man is also in prison. Thoreau: Civil Disobedience (1846)

"Give me your tired, your poor, your huddled masses yearning to breathe free, the wretched refuse of your teeming shore. Send these, the homeless, tempest-tossed to me, I lift my lamp beside the golden door!

We got a thousand points of light for the homeless man. We've got a kinder, gentler, machine gun hand. Neil Young, Rockin' in the Free World.

I'm seeing contradictory evidence too.

My preconception is that ostriches evolved from flighted birds so I'd expect them to have the same urinary structures. The development of a bladder and all the mechanisms that go with it is non-trivial - so if true, it's rather amazing.

However, birds descended from reptiles and apparently some reptiles do have bladders so maybe the answer is parallel development.

Would that explain why you can't hear the Pterodactyl pee?
