The toxic and unpalatable nature of the hooded pitohui has long been known to local people in New Guinea, and this knowledge has been recorded by Western scientists as far back as 1895. [34] In spite of this, and reports of toxicity in birds going back to classic antiquity, before the discovery that the hooded pitohui was toxic, toxicity was ...
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.
Toxic insects, primarily beetles, in the diets of these toxic birds are the most common sources for the bird’s toxicity. In the New Guinea bird species of Pitohui and Ifrita, the beetles of genus Choresine, natively known as nanisani, are pivotal food sources, and toxin sources, of these birds. [6]
The hooded pitohui, found in New Guinea, is a medium-sized songbird with rich chestnut and black plumage. It is one of the few known poisonous birds, containing a range of batrachotoxin compounds in its skin, feathers and other tissues. These toxins are thought to be derived from their diet, and may function both to deter predators and to ...
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 ...

Another odd avifauna from New Guinea is the poisonous birds, notably the hooded pitohui. In 1989, scientists discovered that the hooded pitohui is poisonous. Later, they learned that the feathers and other organs of the pitohui were found to contain batrachotoxin. Since then, six other songbirds in New Guinea have been found to possess the same ...
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.
