The hooded pitohui (Pitohui dichrous) is a pitohui of New Guinea with black and orange plumage. Both male and female birds have colored patches in their plumage. It is the only known poisonous bird, along with the variable pitohui and the rusty pitohui. This species now usually placed in the family Oriolidae.

Toxin[edit]

This species and its two close relatives, the variable pitohui and the rusty pitohui, were the first documented poisonous birds. A neurotoxin called homobatrachotoxin, found in the birds' skin and feathers, causes numbness and tingling in those touching the bird.[2][3]

The hooded pitohui may acquire its poison from part of its diet, the Choresine beetles of the Melyridae family.[4] These beetles are also a likely source of the lethal batrachotoxins found in Colombia's poison dart frogs.[5][6]

Conservation status[edit]

Common and widespread throughout New Guinea, the hooded pitohui is evaluated as least concern on the IUCN Red List of Threatened Species.[7]
