Flying birds toiletry

No idea lol
I think it's all in one....

You're right - not that this was a question I ever expected to see.

Well you know when you are walking and a drip of "water" hits you.

Its not water.

Thanks to all respondents!
I did a web search and now know that most birds have one outlet but just a few do have two.

I was not aware that some had two. For the others, want to know where your eggs come from?

It's all done through a common duct, the cloaca, just the same as reptiles. Both these groups eliminate nitrogen in the insoluble form of uric acid, the white part of the crap. Eliminating nitrogen as uric acid greatly conserves water.
