Until recently, scientists were not aware of the existence of birds that emit or collect a potent poison, and even in large quantities.However, in the early 90-ies of the last century there were studies demonstrating that this ability of some members of the genus Pitohu (lat. Pitohui) and one of a kind Sinegolovoy efreet (Ifrita kowaldi).

Pitohu - a genus of passerine birds that live in the forests of New Guinea.The strongest toxin, similar to the poison of scorpions, frogs or snakes listolaov was found in three species: Pitohui dichrous (bi-color pitohu), Pitohui Kihocephalus (Black pitohu) and Pitohui Ferrugineus (Auburn pitohu).The people of these birds called flyc
atchers Drozdov.

pitohu body weight on average 60-65 kg, while its feathers is 2-3 mg, and in the skin - 15-20 mg of venom batrachotoxin.That would be enough to kill eight hundred mice.Presumably, the toxin is needed for self-defense flycatchers.There is also a hypothesis that the toxin is not produced by the body of the bird, but it builds up over time, as they feed on poisonous beetles nanisani.In its favor is the fact that birds from different populations of the concentration of the poison may differ materially.

batrachotoxin has a powerful cardiotoxic effects, causing an arrhythmia, the heart muscle paralysis, respiratory muscles, and sometimes limbs.Effective antidote to it is still not found between poisoning leads to heart failure.Even a small dose of poison in contact with skin causes severe burns.

Sinegolovaya Ifrit - Guinea also endemic.Locals are well aware of the dangers of this baby - the length of its body does not exceed 16.5 centimeters - but consider it sacred.Ifrit allocated colorful blue and orange feathers, a small crest and a powerful curved beak.Like pitohu in its skin and feathers accumulates batrachotoxin capable of killing any animal and even human.It is noteworthy that sinegolovaya Ifrit is endangered and included in the Red Book (IUCN Red List).

addition to the aforementioned birds to conditionally toxic to birds could be considered living in the rainforests of Australia and Oceania sorokoputovyh flycatchers, African clawed geese and quail, even ordinary, since they occasionally consume toxic insect.
