There are quite a few species of birds that are poisonous. They do not inject venom like snakes, but in its place, generate toxic compounds that reside in their feathers and pores and skin, equivalent to the defenses of some Colombian poison dart frogs. Two of the birds reside solely in New Guinea, these getting the pitohui and the ifrita.
Pitohui is essentially the identify of the genus, and there are 6 species in this genus: Pitohui kirhocephalus, or the Variable Pitohui Pitohui dichrous, or the Hooded Pitohui Pitohui incertus, or the White-bellied Pitohui Pitohui ferrugineus, or the Rusty Pitohui Pitohui cristatus, or the Crested Pitohui and Pitohui nigrescens, or the Black Pitohui.
Pitohuis are omnivorous, ingesting each bugs and vegetation. The pores and skin and feathers of these birds contain batrachotoxins. These are utilized as defenses versus parasites that would live on their pores and skin and feathers, or against predators this kind of as snakes, people, and raptors, which would want to eat the chicken. In point, the Papua New Guineans simply call these birds “rubbish birds” mainly because they are inedible.
Interestingly, the birds do not make the poisons on their own instead they come from a beetle that the birds eat. The other fowl that is harmful, the ifrita, also gets its harmful toxins by ingesting the identical beetles.
The ifrita meaures 16.5 cm prolonged. It is carnivorous, taking in bugs that dwell on tree trunks and branches. The fowl is yellowish brown, with a blue and black crown.
Western researchers discovered the pitohui’s toxicity when trying to totally free the birds from nets that they had set up to catch various birds. John Dumbacher, when he was a doctoral candidate, was just one of the researchers that experienced the neurotoxins 1st hand. The scientists freed the birds from the nets, but, in the approach, bought minimize by the birds’ beaks and claws. The toxin brought on “numbness, burning, and sneezing on call.”
