Hooded pitohui eats bugs and fruit. Scientists suspect this bird's diet is tainted with the toxin homoBTX. This poison deposits on skin, feathers, and dander. Breast, leg, and belly feathers have the most toxicity. Any contact causes tingling, numbness, wet eyes, sneezing, and burning. The bird uses this poison to ward off parasites, including humans, throughout its lifecycle.

This poisonous bird is toxic if eaten. This harmful characteristic is ancient. This hazardous occurrence is called "quail poisoning." Only during autumn migration is this bird toxic (not poisonous during their return flight in spring).
This bird may sequester poison from the insects it eats. Batrachotoxinin-A is this bird's deadly poison. It's the poison dart frog chemical. Poison is stored in the bird's feathers and skin, thus touching them causes a reaction. This poison protects the bird for as long as it can store BTX. The bird's body is resistant to poison.
This species' bellies, leg feathers, and breasts contain batrachotoxins. The blue-capped ifrita may eat BTX (the insects it consumes). The bird's entire lifespan uses BTX. Adults utilise poison to repel predators. Females brush their eggs' underbellies to repel predators, according to researchers. BTX repels parasites, too.
Mullerian mimicry has been recorded in the northern variable and hooded pitohuis. Bird feathers and skin contain BTX. This poison is utilised to prevent predation and repel parasites throughout the bird's lifespan.
Scientific evidence proves the red warbler's toxicity. Toxins in its body provide chemical protection against predators. Neurotoxic alkaloids make them unpleasant and unhuntable. Neurotoxins give them lifelong protection.
Spur-winged geese have toxic spikes on their wings, as their name suggests. The poison in these spikes comes from blister beetles, which contain cantharidin. The bird's tissue contains this toxin, making it poisonous to eat. Lethal dose is 10 milligrammes. The bird's life depends on its toxic weaponry. Its meat is deadly even after death.
This bird's tail and crest are fan-shaped. 18th and 19th-century literature documented ruffed grouse poisoning. No recent grouse-related intoxications have been documented. Consuming quaking aspen flower buds may expose the bird to coniferyl benzoate. The bird seems well-adapted to CB. This chemical made them unpalatable to predators. CB has offered the bird chemical weapons throughout its lifespan.
These birds are toxic. Their toxicity is associated to the extinction of numerous Australian mammals, notably after eating brush bronzewing pigeons. Brush bronzewing pigeons get their poison by eating Gastrolobium seeds, which are high in fluorine. Brush bronzewing pigeons are protected from predators by their tolerance for fluorine.
These birds' uropygial glands create a foul-smelling liquid high in di-methyl sulphide as a chemical defence against predators. Nestlings and breeding birds produce nasty fluids. It protects birds at crucial stages of their lives. This sort of defence is seen in the green woodhoopoe, which gives them group defence.
POISONOUS BIRDS HAVE DEVELOPED MORPHOLOGICAL AND HISTOLOGICAL ADAPTATIONS THAT ALLOW THEM TO USE TOXIC WEAPONRY AT SPECIFIC POINTS IN THEIR LIFECYCLES, MOSTLY IN THE KEEPING OF PREDATORS AND/OR PARASITES.
