Why is bird scat black and white, while everyone else's is brown.

As someone who has to park their car under a tree, I know bird droppings are multicoloured, depending on the particular berries they're eating at various times of year. It's true that a lot are monochrome, but not all by any means.Mammalian scat is typically brown because that is the colour of the breakdown products (mainly stercobilin) of the red haemoglobin from the blood, broken down by the liver, and excreted in bile.
Interesting subject, this site gives more info on other than brown colors, in some cases diagnostic of medical conditions (Stool color: When to worry http://www.mayoclinic.com/health/stool-color/AN00772), or what you've been eating. Bingeing on black licorice yields dark green for some.
Interesting... but I think I'll pass  (that might have been a pun!)
Indeed, science allows us to boldly go where others fear to tread.
