Marabou Stork - Standing up to 5 feet, with a wingspan reported to extend over 10 feet, this stork often kills children who wander too close and are called the undertaker of the bird world due to their ghastly appearance.

African Crowned Eagle - Found in East Africa, this bird can often be found taking down large monkeys, and the occasional human child. Believe it or not, they've also been found to kill antelope.

Greater Honeyguide -Ok this is gruesome. This chick is hatched along with several brothers and sisters. Each comes with a razor sharp beak that won't dull until adulthood. Why does it stick around during its youth? Because this chick will eat its siblings until only one survives. Gross.

Vulturine Guinea Fowl -These highly aggressive, sharp beaked ground stalkers hunt in groups, and unusually for a relative of chickens, capture and kill small mammals. Not too mention they're incredibly creepy looking vultures!

Anhinga -Also known as Snake Birds, these all black birds often rise up from the depths of the water where only their sliver of a beak is exposed. Combined with their penchant for an unusual mating call and slinking back in the water, you never know what they'll go after for dinner next

Hood Mockingbird -Found on the Galapagos Islands, these birds have conquered the lack of food sources on the island by learning to drink the blood of young seabirds while they sit in their nests. Oddly enough, they typically leave the "victim" alive, to one day feast on more blood.

Vampire Finch -Another blood drinker, the small vampire bird is hard to shake off, and will quickly return for more due to its high metabolism

Antarctic Giant Petrel -Weighing up to 18 pounds with a wingspan of 7 feet, the ghastly Giant Petrel stalks the colonies of multiple penguin species. Seriously, they'll take down ANY of them, and you won't see it in any penguin documentary

Great White Pelican -These birds have often been seen eating huge fish and animals...whole. Indeed the Great White was recently filmed at a London park capturing a live pigeon in its massive jaws, before swallowing the bird... alive. Whoa.

Great Gray Shrike -This bird learns to mimic songs sung by other birds, lures them in, and kills them. Just for sport. Seriously

Greater Adjutant - Similar to the Marabou Stork, this bird is a scavenger that can often be seen in India's garbage dumps where it favors human and dog feces
