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.
The birds' bright colours are suggested to be an example of aposematism (warning colouration), and the similarity of the hooded pitohui and some forms of the variable pitohui might then be an example of Müllerian mimicry, in which dangerous species gain a mutual advantage by sharing colouration, so an encounter with either species trains a ...
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.
Some birds are poisonous to eat or touch (e.g. hooded pitohui) though no bird species is known to be venomous. [3] There are only a few species of venomous amphibians; certain salamandrid salamanders can extrude sharp venom-tipped ribs. [4] [5]

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.
