Pitohui
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''. Taxonomy and systematics The Pitohui species were formerly all classified in the genus '' Pitohui'', which at the time was in the family Pachycephalidae. In 2013 they were separated into several different genera in several different families. The species are now separated into three families as follows: Oreoicidae * Crested pitohui ('' Ornorectes cristatus'') Pachycephalidae * Black pitohui ('' Melanorectes nigrescens'') * White-bellied pitohui ('' Pseudorectes incertu ...

Pitohui (genus)
''Pitohui'' is a genus of birds endemic (ecology), endemic to New Guinea. The birds formerly lumped together as pitohuis were found by a 2008 study that examined their evolutionary history on the basis of the genetic sequences to have included birds that were quite unrelated to each other. They have since been separated into other genera. Taxonomy and systematics The genus ''Pitohui'' was introduced in 1831 by the French naturalist René Lesson. Lesson omitted to specify the type species but this was designated as the northern variable pitohui by Richard Bowdler Sharpe in 1877. The genus name is a Papuan languages, Papuan word for the variable pitohui. The common group name pitohui includes several species of birds that were all historically classified in the genus ''Pitohui''. But now they have been separated into three families and multiple genera. The genus ''Pitohui'' in its strict sense is now placed in the family Oriolidae, while the other pitohui genera have been placed ...

Rusty Pitohui
The rusty pitohui (''Pseudorectes ferrugineus'') is a species of bird in the family Pachycephalidae. It is found throughout the lowlands of the Aru Islands and New Guinea.

Batrachotoxin
Batrachotoxin (BTX) is an extremely potent cardiotoxic and neurotoxic steroidal alkaloid found in certain species of beetles, birds, and frogs. The name is from the Greek word . 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. History Batrachotoxin was discovered by Fritz Märki and Bernhard Witkop, at the National Institute of Arthritis and Metabolic Diseases, National Institutes of Health, Bethesda, Maryland, U.S.A. Märki and Witkop separated the potent toxic alkaloids fraction from '' Phyllobates bicolor'' and determined its chemical properties in 1963. They isolated four major toxic steroidal alkaloids including batrachotoxin, homobatrachotoxin (is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pachycephalidae
The Pachycephalidae are a family of bird species that includes the whistlers, shrikethrushes, and three of the pitohuis, and is part of the ancient Australo-Papuan radiation of songbirds. The family includes 69 species that are separated into five genera. Its members range from small to medium in size, and occupy most of Australasia. Australia and New Guinea are the centre of their diversity and, in the case of the whistlers, the South Pacific islands as far as Tonga and Samoa and parts of Asia as far as India. The exact delimitation of boundaries of the family are uncertain, and one species, the golden whistler, has been the subject of intense taxonomic scrutiny in recent years, with multiple subspecies and species-level revisions. Taxonomy and systematics The family Pachycephalidae was introduced (as the subfamily Pachycephalinae) by the English ornithologist William Swainson in 1832. The genera ''Goldenface, Pachycare'', ''Hylocitrea'', the crested bellbird and the crested sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
