They don't urinate. So all the urea (which would normally be in urine) is passed out at the same time as their faeces. Urea is white and their faeces is brown, which is why when you look at it, their droppings are white and brown.

Why is bird poop black with white dot?

Birds do not urinate as people do. Their urine is excreted with their feces. Their feces is actually brownish-black in color and the white you see mixed in with it is the "urine", which is actually very concentrated urea, not urine itself. Also, usually the bird feces can be white with a black spot or dot, not the other way around.

Why is bird poop white?

Bird poop is white because it contains high levels of uric acid, which birds excrete through their waste. Uric acid is a byproduct of protein metabolism and is not water soluble, so it appears as a white paste in the feces. The white color of bird poop also comes from the presence of other waste products and pigments.
