A passerine is any bird of the order Passeriformes which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes, which facilitates perching.
A lyrebird is either of two species of ground-dwelling Australian birds that compose the genus Menura, and the family Menuridae. They are most notable for their impressive ability to mimic natural and artificial sounds from their environment, and the striking beauty of the male bird's huge tail when it is fanned out in courtship display. Lyrebirds have unique plumes of neutral-coloured tailfeathers and are among Australia's best-known native birds.
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin oscen, "songbird". The Passeriformes contains 5,000 or so species found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song.
The Cracticinae, bellmagpies and allies, gathers together 12 species of mostly crow-like birds native to Australasia and nearby areas.
The sittellas are a family, Neosittidae, of small passerine birds found only in Australasia. They resemble nuthatches, but whilst they were considered to be in that family for many years they are now afforded their own family. They do not migrate other than for local movements.
Helpers at the nest is a term used in behavioural ecology and evolutionary biology to describe a social structure in which juveniles and sexually mature adolescents of either one or both sexes remain in association with their parents and help them raise subsequent broods or litters, instead of dispersing and beginning to reproduce themselves. This phenomenon was first studied in birds where it occurs most frequently, but it is also known in animals from many different groups including mammals and insects. It is a simple form of co-operative breeding. The effects of helpers usually amount to a net benefit, however, benefits are not uniformly distributed by all helpers nor across all species that exhibit this behaviour. There are multiple proposed explanations for the behaviour, but its variability and broad taxonomic occurrences result in simultaneously plausible theories.
Barawertornis tedfordi was a dromornithid (mihirung), a large flightless fowl hailing from Late Oligocene to Early Miocene. The only species in the genus Barawertornis, its fossil remains are found in strata of the Riversleigh deposits located at two sites in Northwestern Queensland, Australia.
The superb lyrebird is an Australian passerine songbird, one of two species from the family Menuridae, with the other being the much rarer Albert's lyrebird. It is one of the world's largest songbirds, and is renowned for its elaborate tail and courtship displays, and its excellent mimicry. The species is endemic to Australia and is found in forest in the southeast of the country. According to David Attenborough, the superb lyrebird displays one of the most sophisticated voice skills within the animal kingdom—"the most elaborate, the most complex, and the most beautiful".
The spotted catbird is a species of bowerbird (Ptilonorhynchidae) which can be found in north Queensland, the eastern Moluccas and New Guinea. Although it is a member of the bowerbird family it does not build a bower.
The black honeyeater is a species of bird in the honeyeater family Meliphagidae. The black honeyeater exhibits sexual dimorphism, with the male being black and white while the female is a speckled grey-brown; immature birds look like the female. The species is endemic to Australia, and ranges widely across the arid areas of the continent, through open woodland and shrubland, particularly in areas where the emu bush and related species occur.
The Australian logrunner is a species of bird that is endemic to eastern Australia where it uses unique foraging techniques and adaptations to search for its food on the floors of temperate, subtropical, or tropical moist lowland forests in south-eastern Australia. Until 2002, it was widely considered to be conspecific with the New Guinea logrunner, but studies showed the two differ significantly, both genetically and vocally.
The chowchilla is a passerine bird in the family Orthonychidae. It is endemic to Australia.
The logrunners are two species of birds in the family Orthonychidae. They were previously considered conspecific, but as they differ significantly, they are now generally considered separate species. The family Orthonychidae also contains a third species, the chowchilla.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1993.
Emuarius is an extinct genus of casuariiform flightless bird from Australia that lived during the early Miocene and late Oligocene. It is one of two known genera of emu. There are two known species in the genus, Emuarius gidju and Emuarius guljaruba. The birds in this genus are known as emuwaries. This name comes from a combination of emu and cassowary. This is due to its cassowary-like skull and femur and emu-like lower leg and foot. Because of these similarities it is phylogenetically placed between cassowaries and emus.
Corvitalusoides grandiculus is an extinct species of songbird, in a monotypic genus of uncertain familial affinities, from the Late Oligocene or Early Miocene of northern Australia. It was described from a distal tibiotarsal fragment found at Riversleigh, in the Boodjamulla National Park of north-western Queensland. The bone size indicates that the bird was among the largest of songbirds, within the size range of ravens and lyrebirds.
Menura tyawanoides is an extinct species of lyrebird from the Early Miocene of Australia. It was described by Walter Boles from fossil material found in terrestrial limestone at the Upper Site of Riversleigh, in the Boodjamulla National Park of north-western Queensland. It was smaller than the two living species of lyrebirds. The specific epithet comes from tyawan and the Greek suffix –oides (“resembling”).
Orthonyx kaldowinyeri is an extinct species of logrunner from the Late Oligocene to the Miocene of Australia. It was described by Walter Boles from fossil material found at the Last Minute Site of Riversleigh, in the Boodjamulla National Park of north-western Queensland. It was a relatively small logrunner. The specific epithet kaldowinyeri is an Aboriginal term for “old”, referring to the Miocene age of the species which is earlier than that of other members of the genus.
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.
Riversleigh fauna is the collective term for any species of animal identified in fossil sites located in the Riversleigh World Heritage Area.
