The blue-capped ifrit (Ifrita kowaldi), also known as the blue-capped ifrita, is a small and insectivorous passerine species currently placed in the monotypic family, Ifritidae. [2] [3] Previously, the ifrit has been placed in a plethora of families including Cinclosomatidae or Monarchidae. [2] Blue-capped ifrits are considered an ancient relict species endemic to New Guinea. This corvoid species originally dates back to the Oligocene epoch, on a series of proto-Papuan islands, with minimal known evolutionary divergences. [4]
The blue-capped ifrit is 16–17 cm (6.3–6.7 in) long and weighs 34-36 g (1.2–1.3 oz). [5] Species plumage is yellowish brown with a blue-black crown atop their broad head. It is a sexually dimorphic species, with ear streak coloration being white in males and more tawny yellow in females. [2] Ifrits tend to have more stout body shapes with broad sternums and shallow keels. [2] Their wings are short and rounded while their legs are booted, having feathers down to their stout and clawed feet. [2] Additionally, blue-capped ifrits have batrachotoxin within their feathers and skin. [6]
Blue-capped ifrits are endemic to New Guinea and Papua New Guinea, being found nowhere else on earth and having a distribution of 388,000 km2. [7] Ifrits inhabit montane rainforest of New Guinea, living in altitude ranges of 1,000–4,000 meters (3,280–13,123 feet) above sea level. [2] Typically, they are found at altitudes of 1,500 meters (4,921 feet) or above. [3]
As birds with weak flight abilities, blue-capped ifrits build nests about 1–3 meters (3–10 feet) above the ground in the branches of denser rainforest vegetation. [2] These nests are made of plant fibers with some feathers. The parents tend to camouflage the outside of the nest with moss and liverworts. Ifrits lay small clutches with a typical nest containing only a single offspring. [3] The nest camouflage, toxin excretion, and small clutch sizes may have derived from historically high rates of depredation and nest parasitism. [8]
Blue-capped ifrits are among a small group of avian species that are poisonous, the others being the little shrikethrush ( Colluricincla ), and several members of the Pitohui, also from New Guinea. Ifrits excrete batrachotoxin into their feathers and skin in order to defend themselves against predators. [8] Generally, batrachotoxin binds and permanently opens the sodium channels in nerve cells and can cause paralysis. [9] The accumulation of toxins varies in individuals based on the region they are found in and this could be due to the availability of Choresine beetles, which are speculated to be the dietary source of the toxin itself. [10]
Ifrits are of least concern because they have a large range. Ifrits seem to have a stable population and are thought to have quite a large population size. [5] Part of their range lies within conservation sites. [11]
The grey fantail is a small insectivorous bird. There is no sexual dimorphism. It is a common fantail found in Australia, the Solomon Islands, Vanuatu and New Caledonia. The species is considered by many to be conspecific with the New Zealand fantail ; however, differences in its calls lead some authorities to treat it as a separate species. The studies of grey fantail in 1999 by Richard Schodde and Ian Mason recommended that Tasmanian grey fantail was formally classified as R. albiscapa and New Zealand fantails populations as R. fuliginosa
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 five or six species of whipbirds and wedgebills, but some authors also include the quail-thrushes (Cinclosoma), eight species of ground-dwelling birds found in Australia and New Guinea, and the jewel-babblers (Ptilorrhoa), three or four species found in rainforest in New Guinea. Others place them in their own family, the Cinclosomatidae. The Malaysian rail-babbler was formerly sometimes placed in this family, which would then be called Eupetidae.
The pitohuis are bird species endemic to New Guinea. The onomatopoeic name is thought to be derived from that used by New Guineans from nearby Dorey (Manokwari), but it is also used as the name of a genus Pitohui which was established by the French naturalist René Lesson in 1831. The unitalicized common name however refers to perching birds that belong to several genera of multiple bird families. The genera include Ornorectes, Melanorectes, and Pseudorectes apart from Pitohui.
The hooded pitohui is a species of bird in the genus Pitohui found in New Guinea. It 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.
The black-naped monarch or black-naped blue flycatcher is a slim and agile passerine bird belonging to the family of monarch flycatchers found in southern and south-eastern Asia. They are sexually dimorphic, with the male having a distinctive black patch on the back of the head and a narrow black half collar ("necklace"), while the female is duller with olive brown wings and lacking the black markings on the head. They have a call that is similar to that of the Asian paradise flycatcher, and in tropical forest habitats, pairs may join mixed-species foraging flocks. Populations differ slightly in plumage colour and sizes.
Batrachotoxin (BTX) is an extremely potent cardio- and neurotoxic steroidal alkaloid found in certain species of beetles, birds, and frogs. The name is from the Greek word βάτραχος, bátrachos, 'frog'. Structurally-related chemical compounds are often referred to collectively as batrachotoxins. 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 and death. No antidote is known.
The painted berrypeckers, Paramythiidae, are a very small bird family restricted to the mountain forests of New Guinea. The family comprises three species in two genera: the tit berrypecker in Oreocharis, and the eastern crested berrypecker and western crested berrypecker in Paramythia. 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.
The golden poison frog, also known as the golden dart frog or golden poison arrow frog, is a poison dart frog endemic to the rainforests of Colombia. The golden poison frog has become endangered due to habitat destruction within its naturally limited range. Despite its small size, this frog is considered to be the most poisonous extant animal species on the planet.
The magnificent riflebird is a species of passerine bird in the birds-of-paradise family Paradisaeidae.
Phyllobates is a genus of poison dart frogs native to Central and South America, from Nicaragua to Colombia. There are 3 different Colombian species of Phyllobates, considered highly toxic species due to the poison they contain in the wild.
The lesser melampitta is a medium-sized enigmatic terrestrial songbird of mountain forests of New Guinea. It is the only species in the genus Melampitta. It is now classified in the family Melampittidae, but in some other sources it is variously considered close to or in the Orthonychidae (logrunners), Paradisaeidae, Corcoracidae, Cnemophilidae (satinbirds) or Monarchidae.
The wattled ploughbill is a small bird from New Guinea. It is the only member of the monotypic genus Eulacestoma and family Eulacestomatidae. It is also known as the wattled shrike-tit or ploughshare tit.
The yellow-billed kingfisher(Syma torotoro) is a medium-sized tree kingfisher.
The Golfodulcean poison frog or Golfodulcean poison-arrow frog is a species of frog in the family Dendrobatidae endemic to Costa Rica.
The melampittas are a family, Melampittidae, of New Guinean birds containing two enigmatic species. The two species are found in two genera, the greater melampitta in the genus Megalampitta and the lesser melampitta in the genus Melampitta. They are little studied and before being established as a family in 2014 their taxonomic relationships with other birds were uncertain, being considered at one time related variously to the pittas, Old World babblers and birds-of-paradise.
Melyridae are a family of beetles of the superfamily Cleroidea.
Toxic birds are birds that use toxins to defend themselves from predators. Although no known bird actively injects or produces venom, toxic birds sequester poison from animals and plants they consume, especially poisonous insects. Species include the pitohui and ifrita birds from Papua New Guinea, the European quail, the spur-winged goose, hoopoes, the bronzewing pigeon, and the red warbler.
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.
Cinclosomatidae is a family of passerine birds native to Australia and New Guinea. It has a complicated taxonomic history and different authors vary in which birds they include in the family. It includes the quail-thrushes and jewel-babblers.
The Arafura shrikethrush is a species of bird in the family Pachycephalidae.
