Do birds pee?

I’m sitting here with random thoughts in my head right now, so just bare with me. But I did a little research and here’s what I found.

The short answer is yes and no.

Birds urinate, it’s just that their urine is semisolid rather than liquid.

You see, birds lack a bladder. Instead urine passes from the ureters into the cloaca, a common chamber for the passage of digestive and urinary wastes, as well as for reproductive products. A bird dropping usually contains both white uric acid crystals, and a concentrated mass of digestive wastes such as insect cuticle or seeds.

Mammals remove excess nitrogen from their bodies by converting it to a dilute solution of urea, stored in the bladder. Birds convert nitrogen to uric acid instead: this is metabolically more costly but saves water and weight, as it is less toxic and doesn’t need to be diluted so much. Your Thoughts?

Now, I know that the video below is not a bird peeing but its still equally entertaining.
