Poisonous birds – Not venomous discovered so far
Poisonous birds – No venomous bird has been discovered so far. That is, one whose body would produce a poisonous substance. That would then be transmitted by pecking or wounding with a claw. There are several groups of poisonous birds, that is, poisoning us when we touch or eat them. Their organisms are also probably not producing toxins, but they are able to obtain them from poisonous insects or plants.
Most of them live in New Guinea. Where are several species of Pitohui. Also representatives of the families, store the strong neurotoxin (batrachotoxin) in the skin.
The Gambian Goose from the Anatidae family living in Africa. It accumulates in its tissues another poison, a kantaridine (it gets it from the eaten beetles). Plectropterus gambensis, however, are poisonous only after their consumption. So they gain little thanks to this weapon (except revenge from beyond the grave). On the other hand, other animals of this species benefit from this – a predator who once encountered goose meat will avoid it.
A similar phenomenon applies to the European Common Quail, whose meat is also poisonous, although only for part of the year. Probably quails get their toxin from being eaten plants, and poisoning them are known for a long time and referred to as a coturnism (from the Latin name of the quail Coturnix coturnix).
