Pitohui
Latin
CONT

The birds concerned are species of the genus Pitohui, common medium-sized omnivores that are old endemics of the island of New Guinea. When Dumbacher and colleagues collected and handled a pitohui, they noticed a strong smell and felt numbness and a burning sensation of the mouth... Ethanol extracts yielded the steroidal alkaloid homobatrachotoxin, a nerve and muscle poison previously known only as an active principle of poison-dart frogs(skins of the frogs are used by Amerindians to poison their blowgun darts).

CONT

Il semble que seules trois variétés de pitohuis [...] peut-être quatre, soient venimeuses, d'autres ornithologues ayant disséqué des dizaines d'entre elles sans avoir ressenti des symptômes particuliers. Les concentrations de la toxine [homobatrachotoxine] varient d'une espèce à l'autre et les plus fortes se trouvent chez le pitohui à crête.

[Le pitohui] ayant été sacrifié, on a isolé de sa peau et de ses plumes un poison neurotoxique et curarisant, l'homobatrachotoxine, qu'on avait trouvé que dans la peau de certaines grenouilles venimeuses. Un extrait de 10 mg de peau, injecté à une souris, l'a tuée en quelques minutes.
