This bird is poisonous.
One of only a handful of poisonous bird species in the world, the hooded pitohui (Pitohui dichrous) is considered to be the most toxic. It contains a powerful neurotoxin called homobatrachotoxin in it's skin and feathers. Presumably, the purpose of this toxin is to defend against both parasites that would try to crawl onto it and visual predators like snakes and birds of prey that would learn to associate the bird's bright colors with a bad meal.
Not necessarily lethal to large predators, the toxin causes numbness, tingling, and discomfort when handled by humans.
