If you are still confused and want to investigate what color is bird poop, then we need o go back to the bird’s anatomy.

#1 Birds have only one opening


Birds are truly unique. Birds are built differently than other mammals, as they have only one exit for their urine and poop, called a cloaca.

#2 Birds convert urea to uric acid


The kidney is the organ responsible for urine formation and extraction of nitrogenous waste from the body for both mammals and birds.

However, mammals eliminate these urine wastes mainly in the form of urea. Birds convert it to uric acid or guanine, making it undergo chemical reactions and making bird pee look like a more solid and white substance.

In a nutshell, uric acid is the bird’s urine, which gives people the impression that bird shit white and is probably why it gets extra sticky to your car window.

#3 Bird’s poop reflects their health


Bird poop is white and black in typical circumstances. However, these colors can change and indicate alterations in their diet and wellness.

Commonly, bird poop purple if they feed on blueberries. On the other hand, fresh fruits like grapes, peaches, and watermelons will cause a significant amount of pee in the bird droppings.

However, white and green poop can suggest liver, bacteria, and parasitic infections. For instance, a parrot fever will result in lime-green excrement.
