Australasian Treecreeper
There are seven species of Australasian treecreeper in the passerine bird family Climacteridae. They are medium-small, mostly brown birds with patterning on their underparts, and all are endemic to Australia-New Guinea. They resemble, but are not closely related to, the Holarctic treecreepers. The family is one of several families identified by DNA–DNA hybridisation studies to be part of the Australo-Papuan songbird radiation. There is some molecular support for suggesting that their closest relatives are the large lyrebirds. As their name implies, treecreepers forage for insects and other small creatures living on and under the bark of trees, mostly eucalypts, though several species also hunt on the ground, through leaf-litter, and on fallen timber. Unlike the Holarctic treecreepers they do not use their tail for support when climbing tree trunks, only their feet. Australasian treecreepers nest in holes in trees. The species in the family hold breeding territories, although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Treecreeper
The brown treecreeper (''Climacteris picumnus'') is the largest Australasian treecreeper. The bird, endemic to eastern Australia, has a broad distribution, occupying areas from Cape York, Queensland, throughout New South Wales and Victoria to Port Augusta and the Flinders Ranges, South Australia. Prevalent nowadays between 16˚S and 38˚S, the population has contracted from the edges of its pre-European range, declining in Adelaide and Cape York. Found in a diverse range of habitats varying from coastal forests to mallee shrub-lands, the brown treecreeper often occupies eucalypt-dominated woodland habitats up to , avoiding areas with a dense shrubby understorey. Taxonomy Coenraad Jacob Temminck and Meiffren Laugier de Chartrouse described the brown treecreeper in 1824, and it still bears its original name today. It is one of six species of treecreeper found in Australia, and is most closely related to the rufous treecreeper (''Climacteris rufus'') of Western Australia and t ...

White-throated Treecreeper
The white-throated treecreeper (''Cormobates leucophaea'') is an Australian treecreeper found in the forests of eastern Australia. It is unrelated to the northern hemisphere treecreepers. It is a small passerine bird with predominantly brown and white plumage and measuring some 15 cm (6 in) long on average. It is insectivorous, eating mainly ants. Unlike treecreepers of the genus ''Climacteris'', the white-throated treecreeper does not engage in cooperative breeding, and wherever it overlaps with species of that genus, it feeds upon much looser bark besides typically using different trees. Taxonomy It was first described by ornithologist John Latham in 1801 as ''Certhia leucophaea''. For many years it was classified in the genus ''Climacteris''. The generic name is derived from the Ancient Greek ''kormos'' ' trunk of a tree', and 'batēs' from the verb 'to go' or 'to travel', and refers to its mode of walking up and down trees.Higgins ''et al.'' p. 197 Its specific ...

Red-browed Treecreeper
The red-browed treecreeper (''Climacteris erythrops'') is a species of bird in the family Climacteridae. It is endemic to temperate and subtropical eastern Australia. It is found in mature eucalypt forests and woodlands in both coastal and mountainous regions, from central Victoria to south-eastern Queensland.

White-browed Treecreeper
The white-browed treecreeper (''Climacteris affinis'') is the smallest of the Australo-papuan treecreepers and sole family member adapted to arid environments. The species foraging strategy involves climbing the trunks of trees in search of invertebrate prey on and under bark. Although some populations within the species range have declined, the species IUCN conservation status is of Least Concern. Taxonomy and evolution The white-browed treecreeper (''Climacteris affinis'') is one of 7 species of Australo-Papuan endemic treecreepers (Family: Climacteridae). Prior to the development of molecular diagnostic techniques, the relationship of Climacteridae to other avian families was long debated. Phylogenetic analysis has since revealed the family to be most closely related to bowerbirds and catbirds (Family: Ptilonorhynchidae). Together these two families are thought to represent one of the most ancient linages of ‘songbirds’ (oscines, suborder Passeri), diverging early dur ...

New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; id, Papua, or , historically ) is the world's second-largest island with an area of . Located in Oceania in the southwestern Pacific Ocean, the island is separated from Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf. Numerous smaller islands are located to the west and east. The eastern half of the island is the major land mass of the independent state of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Papua, Central Papua, Highland Papua, South Papua, Southwest Papua, and West Papua. The largest cities on the island are Jayapura (capital of Papua, Indonesia) and Port Moresby (capital of Papua New Guinea). Names The island has been known by various names: The name ''Papua'' was used to refer to parts of the island before contact with the West. Its etymology is unclear; one theory states that ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated ...
