Trivia: Ever heard of a poisonous bird?

The poisonous Pitohui has the same coloration as the poisonous dart frog.

One day in 1989, Jack Dumbacher caught a bird, called a Hooded Pitohui, in a net in New Guinea. The bird bit and scratched at Jack while he was removing it from the net. At some point, Jack put his finger in his mouth. Sometimes, from such things are scientific discoveries made. Well, when Jack Dumbacher put his finger in his mouth, his tongue and lips went numb. After a little panic and a little investigation, it turned out that the pitohui (pronounced "pit-oo-eey," kind of like spitting) was poisonous.

The Hooded Pitohui (Pitohui dichrous, also called the "garbage bird") and the Ifrita (Ifrita kowaldi) from Papua, New Guinea are the first documented poisonous birds. The toxin (homobatrachotoxin, a steroidal alkaloid) is concentrated in these bird's feathers and skin, and is probably obtained from some plant that they eat.

The poison of the pitohui was identified, and it turned out that the poison is a very special one, and had only been seen once before - in dart poison frogs (of the genus Phyllobates in the family Dendrobatidae). Interestingly, the pitohuis and dart poison frogs are also somewhat similar in coloration.

Not much is known about pitohui biology. Major aspects of their life histories remain to be discovered. One of the most important unknown things is how they make homobatrachotoxin, and how the birds themselves survive the poison in their bodies. There is enough unknown to provide several people with lifetime research projects.
