Kookaburra Close-up
Kookaburras are terrestrial tree kingfishers of the genus ''Dacelo'' native to Australia and New Guinea, which grow to between in length and weigh around . The name is a loanword from Wiradjuri ''guuguubarra'', onomatopoeic of its call. The loud, distinctive call of the laughing kookaburra is widely used as a stock sound effect in situations that involve an Australian bush setting or tropical jungle, especially in older movies. They are found in habitats ranging from humid forest to arid savannah, as well as in suburban areas with tall trees or near running water. Though they belong to the larger group known as "kingfishers", kookaburras are not closely associated with water. Taxonomy The genus ''Dacelo'' was introduced by English zoologist William Elford Leach in 1815. The type species is the laughing kookaburra. The name ''Dacelo'' is an anagram of ''alcedo'', the Latin word for a kingfisher. A molecular study published in 2017 found that the genus ''Dacelo'', as currently ...

Laughing Kookaburra
The laughing kookaburra (''Dacelo novaeguineae'') is a bird in the kingfisher subfamily Halcyoninae. It is a large robust kingfisher with a whitish head and a brown eye-stripe. The upperparts are mostly dark brown but there is a mottled light-blue patch on the wing coverts. The underparts are cream-white and the tail is barred with rufous and black. The plumage of the male and female birds is similar. The territorial call is a distinctive laugh that is often delivered by several birds at the same time, and is widely used as a stock sound effect in situations that involve a jungle setting. The laughing kookaburra is native to eastern mainland Australia, but has also been introduced to parts of New Zealand, Tasmania, and Western Australia. It occupies dry eucalypt forest, woodland, city parks and gardens. This species is sedentary and occupies the same territory throughout the year. It is monogamous, retaining the same partner for life. A breeding pair can be accompanied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onomatopoeia
Onomatopoeia is the process of creating a word that phonetically imitates, resembles, or suggests the sound that it describes. Such a word itself is also called an onomatopoeia. Common onomatopoeias include animal noises such as ''oink'', ''meow'' (or ''miaow''), ''roar'', and ''chirp''. Onomatopoeia can differ between languages: it conforms to some extent to the broader linguistic system; hence the sound of a clock may be expressed as ''tick tock'' in English, in Spanish and Italian (shown in the picture), in Mandarin, in Japanese, or in Hindi. The English term comes from the Ancient Greek compound ''onomatopoeia'', 'name-making', composed of ''onomato''- 'name' and -''poeia'' 'making'. Thus, words that imitate sounds can be said to be onomatopoeic or onomatopoetic. Uses In the case of a frog croaking, the spelling may vary because different frog species around the world make different sounds: Ancient Greek (only in Aristophanes' comic play ''The Frogs'') probably ...

Shovel-billed Kookaburra
The shovel-billed kookaburra (''Clytoceyx rex''), also known as the shovel-billed kingfisher, is a large, approximately 33 cm (13 in) long, dark brown tree kingfisher with a heavy, short, and broad bill that is unique among the kingfishers. It has a dark head with a rufous stripe behind the eyes, a white throat, a rufous neck collar and underparts, a bright blue rump, brown iris, brownish-black bill with paler mandible (entire bill often appears brownish due to earth), and pale feet. Both sexes are similar in appearance, but are easily recognized from the colour of the tail. The male has a dark bluish tail while female's is rufous. The juvenile has a female-like plumage with scale-patterned feathers. The sole representative of the genus ''Clytoceyx'', the shovel-billed kookaburra is endemic to New Guinea. No subspecies are recognised because the differences in plumage between the races ''imperator'' and ''septentrionalis'' is small. It primarily occurs in hill forests, ...

Australia (continent)
The continent of Australia, sometimes known in technical contexts by the names Sahul (), Australia-New Guinea, Australinea, Meganesia, or Papualand to distinguish it from the country of Australia, is located within the Southern and Eastern hemispheres. The name "Sahul" takes its name from the Sahul Shelf, which is a part of the continental shelf of the Australian continent. The continent includes mainland Australia, Tasmania, the island of New Guinea (Papua New Guinea and Indonesian Western New Guinea), the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands. Situated in the geographical region of Oceania, Australia is the smallest of the seven traditional continents. The continent includes a continental shelf overlain by shallow seas which divide it into several landmasses—the Arafura Sea and Torres Strait between mainland Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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 dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aru Islands Regency
The Aru Islands Regency ( id, Kabupaten Kepulauan Aru) is a group of about 95 low-lying islands in the Maluku Islands of eastern Indonesia. It also forms a regency of Maluku Province, with a land area of . At the 2011 Census the Regency had a population of 84,138;Biro Pusat Statistik, Jakarta, 2011. the 2020 Census produced a total of 102,237. Some sources regard the archipelago as part of Asia, while others regard it as part of Melanesia. Administration At the time of the 2010 Census, the regency was divided into seven districts (''kecamatan''), but subsequently an additional three districts have been created by the splitting of existing districts. The districts are tabulated below with their areas (in km2) and their populations at the 2010 Census and 2020 Census. The table also includes the locations of the district administrative centres, the number of villages (''desa'') in each district, and its postal code.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Paraphyly
In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and most of its descendants, excluding a few monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia ( reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor, including all extant reptiles as well as the extinct synapsids, ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Kingfisher
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly colored birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species found in the tropical regions of Africa, Asia, and Oceania, but also can be seen in Europe. They can be found in deep forests near calm ponds and small rivers. The family contains 114 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests. They consume a wide range of prey usually caught by swooping down from a perch. While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates. Like other members of their order, they nest in cavities, usually tunnels dug into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
