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 64 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 John Swainson in 1832. [1] [2]

The genera Pachycare , Hylocitrea , the crested bellbird and the crested shriketit were previously included in the family Pachycephalidae until moved to the families Acanthizidae, Hylocitreidae and Oreoicidae and Falcunculidae respectively. [3] Some authorities have also placed the genus Mohoua , classified in the monotypic family Mohouidae, within the family Pachycephalidae. [4]

The whistler family has five extant genera as follows: [3]

Pachycephalidae

Pseudorectes – pitohuis (2 species)

Colluricincla – strikethrushes (11 species)

Melanorectes – black pitohui

Coracornis – whistler and strikethrush (2 species)

Pachycephala – typical whistlers (48 species)

Description

The whistlers are stout birds with strong bills, and the group was once known as the thickheads due to the large rounded heads of many species. Their plumage is rufous, brown, or grey in the majority of species. Nevertheless, a few species, particularly the golden whistler and its close relatives, have bright plumage. One of the more unusual traits of this family is found in the feathers of some of the pitohuis, which have toxins. [6] These toxins are probably a deterrent to parasites and may also serve to dissuade predators from taking the birds.

Vocalisations

Several species belonging to this family are outstanding songsters: the whistlers produce an astonishing volume for their size, and the lyrebirds aside, the grey shrikethrush is often regarded as the finest, most inventive songbird of them all.[ citation needed ]

Distribution and habitat

The whistlers are birds of forests and wooded areas. Most species inhabit rainforest, particularly in the Asian and Papuan parts of their range, but Australian species inhabit a wider range of habitats including woodlands, arid scrubland and mangrove forests. Some species are restricted to a particular ecosystem, whereas others are more catholic and will inhabit a range of habitat types.

Behaviour and ecology

Breeding

Little is known about the breeding biology of most of the family; what is known generally comes from a small number of Australian species and the three New Zealand Mohoua species. They are monogamous and generally nest as simple pairs, although breeding groups have been recorded in some species.

Food and feeding

They are insectivorous, picking insects off leaves, branches, or leaf litter. While insects make up the majority of the diet they will also feed on spiders, worms, centipedes, snails, and small crabs; larger species will also tackle small vertebrates such as frogs, geckos and baby birds. They are generally sedate foragers and do not engage in hawking to obtain prey, instead being gleaners and probers. Only a few species migrate, most remaining resident in their tropical environment.

The birds-of-paradise are members of the family Paradisaeidae of the order Passeriformes. The majority of species are found in eastern Indonesia, Papua New Guinea, and eastern Australia. The family has 45 species in 17 genera. The members of this family are perhaps best known for the plumage of the males of the species, the majority of which are sexually dimorphic. The males of these species tend to have very long, elaborate feathers extending from the beak, wings, tail, or head. For the most part, they are confined to dense rainforest habitats. The diet of all species is dominated by fruit and to a lesser extent arthropods. The birds-of-paradise have a variety of breeding systems, ranging from monogamy to lek-type polygamy.

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.

<i>Lanius</i> Genus of birds

Lanius, the typical shrikes, are a genus of passerine birds in the shrike family Laniidae. The majority of the family's species are placed in this genus. The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.

<i>Pachycephala</i> Genus of birds

Pachycephala is a genus of birds native to Oceania and Southeast Asia. They are commonly known as typical whistlers. Older guidebooks may refer to them as thickheads, a literal translation of the generic name, which is derived from the Ancient Greek terms pachys "thick" + kephale "head". This lineage originated in Australo-Papua and later colonized the Indonesian and Philippine archipelagos to the west and the Pacific archipelagos to the east.

Shrikethrushes are generally insectivorous, though have been recorded eating molluscs and berries. They build cup-shaped nests in the forks of trees.
