We have two birds, an African Grey Parrot and a Blue and Gold Macaw. Yes they do urinate...it comes out with the poo. You know that white stuff.....well that's the urine and the greeny stuff that's the poo!
So when someone says a bird pooed on them often they got weed on!!

Birds urinate, it's just that their urine is semisolid rather than liquid.
Birds excrete their nitrogenous wastes, derived mostly from the breakdown of proteins, in the form of uric acid rather than urea as mammals do. Unlike urea, uric acid is almost insoluble in water, and is excreted in the form of crystals that form a semisolid white paste. Not needing to store liquid wastes, 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.
Most aquatic vertebrates excrete nitrogenous wastes in the form of ammonia, which is highly toxic but very soluble and easily gotten rid of if water is in ample supply. Uric acid excretion may have first developed in the first vertebrates to evolve shelled, fully terrestrial eggs. Such eggs must retain the waste products produced by embryonic metabolism within the shell until hatching. Toxic, soluble ammonia would soon poison a developing embryo, while non-toxic, insoluble uric acid can simply be stored inside the shell as long as necessary. In developing live birth, mammals may have switched to back to a more soluble compound, urea, so that embryonic waste products could be diffused into the blood stream of the mother and thus excreted.

Yeah, I'm full of useless knowledge today. Birds do urinate, but its in a different form to what you think it would be. A bird's wee is basically the white bit that is mixed in with the green bit when they poop. Sorry to be graphic!

Everybody urinates. Including birds and all other animals. Anyone who doesn't would poison themselves from the inside. In answer to your other question, I haven't yet had the pleasure of a bird pi**ing on me.

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?

I don't think birds urinate in the same way that humans do. It's done at the same time the bird dropping lands on your head, meaning they sh1t and piss in one drop.

Birds have their urine and feces exiting from the same source. This is why their feces is always semisolid.
