It is believed that these birds gain their toxicity through the consumption of a toxic beetle.

The Hooded Pitohui is one of a small number of birds known to be poisonous. In fact, The Guiness Book of World Records says that the Hooded Pitohui is the "Most Poisonous Bird". The bird, native to Papua New Guinea, was discovered in 1990, and has puzzled scientists ever since. I was curious about the beetle, nova. More research required for that ; )
