The research paints a clearer picture of how vultures’ strong stomach acid permits a diet of rotten carcasses, a fact that scientists have known for years.

Researchers specifically focused their study on the DNA of bacteria found in the vulture’s stomach, discovering that of the hundreds of bacteria present on the beak, only two dominated their guts, a “remarkably conserved low diversity of gut microbial flora,” the study said.
