 Discovery of its toxicity

The bicolor Pitohui is so common that it has been known for more than a century. However, it was not until 1990 that its toxicity was discovered.

Indeed, Jack Dumbacher was scratched with a paw. He noticed that his lips and tongue began to tingle and burn as he licked his wound, the effect of the poison lasting for several hours. Later, he put a pitohui feather in his mouth and the same effect happened, but stronger: “like a 9V battery”.

He later published his discovery, as no poisonous birds were then known to the scientific community.

One of the main toxins of this bird is homobatrachotoxin, an alkaloid with a steroid structure similar to batrachotoxin found in the venom of frogs of the genus Phyllobates.
