  3. Unlike mammals, birds don't urinate. Their kidneys extract nitrogenous wastes from the bloodstream, but instead of excreting it as urea dissolved in urine as we do, they excrete it in the form of uric acid. Uric acid has a very low solubility in water, so it emerges as a white paste

  4. Interesting...We pee to get rid of ammonia, which is converted to urea by liver (I think). Pee is yellow from byproducts of breakdown of bile pigment bilirubin (again done in liver?)
