The plumage of the hooded pitohui is dichromatic, black and reddish brown. The hooded pitohui is 22 to 23 cm (8.7–9.1 in) long and weighs 65–76 g (2.3–2.7 oz). The adult has a black upperwing, head, chin, throat and upper breast and a black tail. The rest of the plumage is a reddish brown.
Hooded pitohui. The pitohuis / p ɪ t oʊ ˈ w iː / [1] are bird species endemic to New Guinea.The onomatopoeic name is thought to be derived from that used by New Guineans from nearby Dorey (), but it is also used as the name of a genus Pitohui which was established by the French naturalist René Lesson in 1831.
The hooded pitohui. The neurotoxin homobatrachotoxin on the birds' skin and feathers causes numbness and tingling on contact. The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested.
The first research done on toxic birds was published in 1992 by Dumbacher et al., [4] which found traces of the neurotoxin homobatrachotoxin, a steroid alkaloid with the ability to polarize Na+ channels, in the feathers and body tissue of many species of New Guinea passerine birds of the genus Pitohui and Ifrita.

[2] [3] Several other genera have been proposed to split up the genus Oriolus. For example, the African black-headed species are sometimes placed in a separate genus, Baruffius . The family Oriolidae is not related to the New World orioles , despite their similar size, diet, behaviour and contrasting plumage patterns.
Pitohui is a genus of birds endemic to New Guinea.The birds formerly lumped together as pitohuis were found by a 2008 study that examined their evolutionary history on the basis of the genetic sequences to have included birds that were quite unrelated to each other.
Several species of bird endemic to New Guinea have the toxin in their skin and on their feathers: the blue-capped ifrit (Ifrita kowaldi), little shrikethrush (aka rufous shrike-thrush, Colluricincla megarhyncha), and the following pitohui species: the hooded pitohui (Pitohui dichrous, the most toxic of the birds), crested pitohui (Ornorectes ...
