Why is bird poop white?
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. This material, as well as the output of the intestines, emerges from the bird's cloaca. The cloaca is a multi-purpose hole for birds: their wastes come out of it, they have sex by putting their cloacas together, and females lay eggs out of it.

It's not always white. You should see the colour of the seagull **** on my car when they've been eating blackberries !
because it has a high lime content
It must be something in what they eat and their own body chemistry
For the same reason yours isn't.... Ewww... Who cares why it's any color???
because they mainly eat seeds, maize and bread which contributes to the colour of their doodies
Not all bird poo is white... it basically depends on what they eat and on the digestive system... this goes to all living creatures not just birds. For example, I had a pigeon once that ate lots of dried green peas... she used to poo green.
