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.

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.
These toxins are thought to be derived from their diet, and may function both to deter predators and to protect the bird from parasites. The toxic nature of this bird is well known to local hunters, who avoid it. The hooded pitohui is found in forests from sea level up to 2,000 metres (6,600 ft), but is most common in hills and low mountains.
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.
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 ...

A, the latter as yet unnamed) have been found to contain batrachotoxins, which may account for the toxicity of some birds such as the blue-capped ifrit and hooded pitohui which eat them. The hypothesis that Phyllobates frogs in South America obtain batrachotoxins from related genera of the Melyridae ( Choresine does not occur there) has not ...
