Most mistletoe seeds are spread by birds who eat the 'seeds' (in actuality drupes). Of the many bird species that feed on them, the mistle thrush is the best-known in Europe, the phainopepla in southwestern North America, and Dicaeum flowerpeckers in Asia and Australia. Depending on the species of mistletoe and the species of bird, the seeds ...
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.
The close resemblance of this species to other unrelated birds also known as pitohuis which are also poisonous is an example of convergent evolution and Müllerian mimicry. Their appearance is also mimicked by unrelated non-poisonous species, a phenomenon known as Batesian mimicry. The toxic nature of this bird is well known to local hunters ...
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 birds' bright colours are suggested to be an example of aposematism (warning colouration), and the similarity of the hooded pitohui and some forms of the variable pitohui might then be an example of Müllerian mimicry, in which dangerous species gain a mutual advantage by sharing colouration, so an encounter with either species trains a ...
