A group of vultures— called a “wake”— can consume an entire 150-pound corpse in just a few hours! Of course, those corpses are generally deer, but if you find yourself in a post-apocalyptic scenario surrounded by zombies, your vulture neighbors would come in handy.
These amazing birds are quickly attracted to the smell of decay and will descend on anything dead (or, presumably, undead). Their cast-iron stomachs are full of powerful, acidic compounds that disinfect whatever they eat. A vulture’s belly can kill salmonella, E. coli, anthrax, and presumably whatever zombifying plague is going around.
Maybe we’re not likely to need them as zombie destroyers, but these animals are important to our world. Vultures keep our entire planet cleaner and healthier for everyone.
