Comprehensive Description

Hooded Pitohui

The Hooded Pitohui, Pitohui dichrous is a songbird of New Guinea with black and orange plumage.

This species and its two close relatives, the Variable Pitohui and the Brown 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.

The Hooded Pitohui acquires its poison from part of its diet, the Choresine beetles of the Melyridae family. These beetles[verification needed] are also a likely source of the lethal batrachotoxins found in Colombia's poison dart frogs.[1]

Common and widespread throughout New Guinea, the Hooded Pitohui is evaluated as Least Concern on the IUCN Red List of Threatened Species.

Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Hooded pitohui

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. 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]
