Didn't know it's illegal to own them. I'm glad they're being protected. I think they lay only one egg a year? And it's a good percentage of their body size! I can see how that would make them slow to breed and prevent their population from rapidly increasing.
Not even Kiwis are completely wingless. They have rudimentary wing stubs that can't be seen under all those body feathers. It's so interesting how the ratites evolved to be flightless, yet never completely lost the physical protrusions that may, at one time, have been fully developed wings, or which never fully developed into wings to begin with. Instead, they became runners and kickers.
Bird evolution is fascinating ...
