5/2/2002: Shit-eating bird

This is the Egyptian vulture. Scientists believe that its beautiful orange beak and yellow face helps it to attract mates.

But it has a problem: that coloring is produced by beta-carotene, and the bird needs a ton of beta-carotene to produce good coloration.

The best place to find beta-carotene, it turns out, is in the feces of hooved animals. And so the bird scarfs down that dung.
