1. Hooded Pitohui: The hooded pitohui of New Guinea is the only documented example of a poisonous bird (yes, a bird). In 1992 researchers discovered that the feathers and skin of the hooded pitohui contain a powerful neurotoxin called homobatrachotoxin, which causes numbness and tingling skin in people who touched the birds. Be carefull.
