Not one, but six species of poisonous birds have been found so far and they all live in the rainforests of Papua New Guinea, Southeast Asia. One of the species is Pitohui (see photo). Poisonous birds have high concentrations of batrachotoxin in their belly, breast and leg feathers. The toxin can numb or paralyze on contact. Needless to say, the poison protects them from the predators.
