Question:
Why is there a Black Dot in the middle of otherwise White Bird Droppings?

Options:
1. It is left over bird seed.
2. It is really poop.
3. It is ungrown feathers.
4. I don't know.

Answer:
That black dot is fecal matter. The white stuff is urine. The urine and fecal matter of birds collect together and are discarded simultaneously out the same orifice. Feces tend to sit directly in the middle of droppings because the urine, slightly sticky in consistency, clings to them.
