The opening of this video is great, as Dr. Jack Dumbacher, Curator of Birds and Mammals at the California Academy of Sciences, talks about his field expeditions to Papua New Guinea. His hunch after being bitten while releasing a bird from a net is that it may be poisonous. He checks with locals and they all confirm "those birds are poisonous and you shouldn't be touching them."

The video description on YouTube states "Some of the best discoveries in science are completely serendipitous. Dr. Dumbacher discovered, quite by accident, that a common New Guinea bird, Variable Pitohui (Pitohui kirhocephalus) uses potent poisons for protection -- a defense never before documented in birds."
