Question:
Which species of birds are the olny ones that urinate?


Replies:
As far as I know, all birds urinate, but their waste contains uric acid instead of urea. The white stuff you see on the ground is bird urine, the uric acid turns it white. The solid material in some bird urine is actually fecal matter. Are you asking whether some birds urine is urea-based instead of uric acid-based?

Van Hoeck


Birds do not urinate. Their cloaca combines solid and liquid wastes.
