Birds have bowels and kidneys, just like mammals, but they don’t dispose of the wastes separately. When they dump, you get both feces and urine, not very well mixed. And the colour varies quite a bit. I suppose it depends mostly on diet. ---

Moreover, a bird’s urinary system is set up to conserve water so it excretes a concentrated uric acid as opposed to the dilute urine we do. Hence the sticky pellet like consistency. ---

It does depends on what the bird has eaten. Our east-side neighbor had large streaks of purple all over his white siding until he convinced our west-side neighbor to remove his grape arbors. Evidently the birds would get far enough beyond our house to miss our white siding most of the time. Just curious, not sarcastic - why are you asking this here in MPSIMS and not GQ? ---

Could be that jay’s just being nice to the mods. This thread would probably have been moved here eventually. ---

“Why is bird shit coloured?” —Bird is shit coloured to blend in with trees. So bird not get eaten. Why you talk like Tonto? ---
