The Pitohui - Idi Nachui
Ladies and gentlemen science has finally triumphed as we have managed to successfully hybridize the wasp and the crow. This little cunt of a birb is known as the Pitohui.
So what sets this cawbuzz apart from other birds. Well this nasty little bugger has a habit of excreting a powerful toxin out of its skin and feathers. This toxin is otherwise known as batrachotoxin.
Now what is Batrachotoxin exactly? Batrachotoxin was a toxin originally found in frogs. It is a neurotoxin that has the ability to numb the nervous system, which can later on lead to full on paralysis. This bird does not play any games.
So in which section of Blighttown does the Pitohui naturally appear in? All Pitohui species are native to New Guinea. Australians can rejoice knowing that they don't have to deal with toxic birds, they just have to dodge and cull gigantic raptors.
For what reason does the Pitohui need to carry poison for? The batrachotoxin that the Pitohui carries is used a defense system against visually guided predators like snakes, raptors and humans. Humans can still eat their meat in dire situation via thorough process which involves carefully roasting it. I don't know why you'd want to eat a toxic animal however, but I'm no Duke Venomania.
The Pitohui proves that it doesn't take gigantic claws or a sharp beak to defend oneself. All it takes is a nice thin layer of toxin and you're all set. If you ever feel like you're weak or bullied, then just start excreting bathrachotoxin from your skin and hair. It does great work on acne.
