Blue-capped ifrit

The blue-capped ifrit (Ifrita kowaldi), also known as the blue-capped ifrita, is a small insectivorous bird endemic to the rainforests of New Guinea. It is the only species in the genus Ifrita, which historically has been placed in the family Cinclosomatidae or the Monarchidae. It now appears the bird is more properly placed in its own family, Ifritidae.[2]

Description

They are between 16 and 17cm long and weigh between 34 and 36 g.[3] Their plumage is yellowish brown with a crown that is blue and black.[4] Males of this species have a white streak behind their eyes and the females have a dullish yellow stripe instead.[5]

Poison

This bird is one of only a few birds known to have poisonous members, the others being the little shrikethrush (Colluricincla), and several members of the Pitohui, also from New Guinea. It, like the hooded pitohui, sequesters batrachotoxin in its skin and feathers, which causes numbness and tingling to those who handle the bird. The toxin is acquired from part of its diet, specifically Choresine spp. beetles.[6]

Distribution and conservation

They are found on New Guinea and Papua New Guinea. The blue-capped ifrit is evaluated as least concern on the IUCN Red List of Threatened Species, though there is an unknown number of mature individuals. the range is unfragmented. There are conservation areas in parts of its range.[7]

It is of least concern because is has a large range, seems to have a stable population and is thought to have quite a large population size.[8]

Batrachotoxin

Batrachotoxin (BTX) is an extremely potent cardiotoxic and neurotoxic steroidal alkaloid found in certain species of beetles, birds, and frogs. Batrachotoxin was derived from the Greek word βάτραχος bátrachos "frog". Structurally-related chemical compounds are often referred to collectively as batrachotoxins. It is an extremely poisonous alkaloid. In certain frogs this alkaloid is present mostly on the skin. Such frogs are among those used for poisoning darts. Batrachotoxin binds to and irreversibly opens the sodium channels of nerve cells and prevents them from closing, resulting in paralysis - no antidote is known.

Choresine

Choresine is a genus of beetles that belong to the Melyridae family. This genus of beetle is known to have high levels of batrachotoxins and is believed to be a possible toxin source for Pitohui and Blue-capped ifrit birds in New Guinea. Collections from Herowana in the Eastern Highlands Province that tested positive for batrachotoxins included the more abundant C. pulchra, the less abundant C. semiopaca and the two infrequent C. rugiceps and C. sp. A, the latter as yet unnamed. The locals advise against allowing these beetles to touch the eyes or sweaty face as a severe burning sensation can result. These species are all described as having metallic blue-violaceous elytra and a yellow and blackish pronotum. The name "nanisani" is used by villagers in Herowana equally for this group of insects, the numbing, tingling, burning sensation they cause and the Blue-capped ifrit.

The hypothesis that Phyllobates frogs in South America obtain batrachotoxins from related genera of the Melyridae (Choresine does not occur there) has not been tested due to the difficulty of field-work in Colombia.

Hooded pitohui

The hooded pitohui (Pitohui dichrous) is a species of bird in the genus Pitohui found in New Guinea. The species was long thought to be a whistler (Pachycephalidae) but is now known to be in the Old World oriole family (Oriolidae). Within the oriole family this species is most closely related to the variable pitohuis in the genus Pitohui, and then the figbirds.

A medium-sized songbird with rich chestnut and black plumage, this species is one of the few known poisonous birds, containing a range of batrachotoxin compounds in its skin, feathers and other tissues. These toxins are thought to be derived from their diet, and may function both to deter predators and protect the bird from parasites. 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 species is well known to local hunters, who avoid it. This species is one the most poisonous species of pitohui, but the toxicity of individual birds can vary geographically.

The hooded pitohui is found in forests from sea-level up to 2,000 m (6,600 ft), but is most common in hills and low mountains. A social bird, it lives in family groups and frequently joins and even leads mixed-species foraging flocks. The diet is made up of fruits, seeds and invertebrates. This species is apparently a cooperative breeder, with family groups helping to protect the nest and feed the young. The hooded pitohui is common and not at risk of extinction.

List of least concern birds

As of May 2019, the International Union for Conservation of Nature (IUCN) lists 8405 least concern avian species. 76% of all evaluated avian species are listed as least concern.

No subpopulations of birds have been evaluated by the IUCN.

Melyridae

Melyridae (common name: soft-wing flower beetles) are a family of beetles of the superfamily Cleroidea.

Painted berrypecker

The painted berrypeckers, Paramythiidae, are a very small bird family restricted to the mountain forests of New Guinea. The family comprises two species in two genera: the tit berrypecker (Oreocharis arfaki) and the crested berrypecker (Paramythia montium). These are colourful medium-sized birds which feed on fruit and some insects. These species were formerly included in the Dicaeidae, but DNA–DNA hybridization studies showed these species were related to each other but distinct from the flowerpeckers. Some sources group painted berrypeckers as two genera belonging to the berrypecker family Melanocharitidae.

Passerine

A passerine is any bird of the order Passeriformes, which includes more than half of all bird species. Sometimes known as perching birds or – less accurately – as songbirds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching, amongst other features specific to their evolutionary history in Australaves.

With more than 110 families and some 6,409 identified species, Passeriformes is the largest order of birds and among the most diverse orders of terrestrial vertebrates. Passerines are divided

into three clades, Acanthisitti (New Zealand wrens), Tyranni (suboscines) and Passeri (oscine).The passerines contain several groups of brood parasites such as the viduas, cuckoo-finches, and the cowbirds. Most passerines are omnivorous, while the shrikes are carnivorous.

The terms "passerine" and "Passeriformes" are derived from the scientific name of the house sparrow, Passer domesticus, and ultimately from the Latin term passer, which refers to sparrows and similar small birds.

Psophodidae

Psophodidae is a family of passerine birds native to Australia and nearby areas. It has a complicated taxonomic history and different authors vary in which birds they include in the family. In the strictest sense, it includes only the 5 or 6 species of whipbirds and wedgebills (Psophodes and Androphobus), but some authors also includes at the quail-thrushes (Cinclosoma), 8 species of ground-dwelling birds found in Australia and New Guinea, and the jewel-babblers (Ptilorrhoa), 3 or 4 species found in rainforest in New Guinea. The Malaysian rail-babbler (Eupetes macrocerus) was formerly sometimes placed in this family, which would then be called Eupetidae.
