Little Grassbird
The little grassbird (''Poodytes gramineus'') is a species of Old World warbler in the family Locustellidae. It is found in Australia and in West Papua, Indonesia. These sexually monomorphic birds are found in reed beds, rushes, lignum swamps and salt marshes of Southeastern Australia. The little grassbird is an inconspicuous and dull-coloured bird that is heard more regularly than it is seen, known for readily engaging in conversation with people. They feed on insects and small arthropods, usually remaining in densely covered areas of vegetation and living nomadically with no regular migration patterns.Pizzey, G., Knight, D., Pizzey, S,. (1997). The Field Guide to the Birds of Australia by Graham Pizzey and Frank Knight. 470(3). Retrieved 13 June 2018 Taxonomy Old World warblers are a large group of birds formerly grouped together in the family Sylviidae. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Grass warblers are so ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Slater Field Guide To Australian Birds
''The Slater Field Guide to Australian Birds '' is one of the main national bird field guides used by Australian birders. Description The guide was first published in 1986 in Sydney by Rigby Publishers and authored by Peter Slater and other members of his family. It is 215 mm high by 113 mm wide and weighs 440 g. The imprint page asserts copyright of the paintings for Peter Slater, of the text for Pat Slater, and of the maps for Raoul Slater. History In 1970-74 Slater had produced a two-volume guide to Australian birds which was the first of the new generation of Australian field guides to appear after the Second World War. It was shortly followed by guides authored by Graham Pizzey in 1980 and by Ken Simpson and Nicolas Day in 1984. Slater's second guide continued the evolutionary succession only two years later. In a review in the ornithological journal ''Emu The emu () (''Dromaius novaehollandiae'') is the second-tallest living bird after its ...

Birds Of Western New Guinea
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Australia
Australia and its offshore islands and territories have 898 recorded bird species as of 2014. Of the recorded birds, 165 are considered vagrant or accidental visitors, of the remainder over 45% are classified as Australian endemics: found nowhere else on earth. It has been suggested that up to 10% of Australian bird species may go extinct by the year 2100 as a result of climate change. Australian species range from the tiny weebill to the huge, flightless emu. Many species of Australian birds will immediately seem familiar to visitors from the Northern Hemisphere: Australian wrens look and act much like northern wrens, and Australian robins seem to be close relatives of the northern robins. However, the majority of Australian passerines are descended from the ancestors of the crow family, and the close resemblance is misleading: the cause is not genetic relatedness but convergent evolution. For example, almost any land habitat offers a nice home for a small bird that specia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Australasian Swamphen
The Australasian swamphen (''Porphyrio melanotus'') is a species of swamphen (''Porphyrio'') occurring in eastern Indonesia (the Moluccas, Aru and Kai Islands), Papua New Guinea, Australia and New Zealand. In New Zealand, it is known as the pukeko (from the Māori ). The species used to be considered a subspecies of the purple swamphen. Distribution The Australasian swamphen occurs in mainland Australia, eastern Indonesia, the Moluccas, Aru and Kai Islands, and in Papua New Guinea. It is also found on New Zealand's main islands and in the Chatham and Kermadec Islands. It has a small shield, black upperparts, and a purple throat and breast. ''P. p. pelewensis'' (Hartlaub & Finsch, 1872) from Palau, resembles ''melanotus'' but has greener upperparts and is smaller. ''P. p. melanopterus'' (Bonaparte, 1856) is found from the Lesser Sundas and Moluccas to New Guinea. It is as ''melanotus'' but smaller, more variable and less blue in the upperparts.

Striated Fieldwren
The striated fieldwren (''Calamanthus fuliginosus'') is a species of bird in the family Acanthizidae, endemic to Australia. Description The striated fieldwren is a small bird, 140mm in size. It is light brown and olive-colored, with a white stomach, and black streaks all over. Its tail is cocked and whitish with black and brown streaks. The striated fieldwren’s front is buff with dark gray and brown streaks; their wings are also brown and gray but with darker and bolder streaks. The bird’s flight feathers, however, do not have streaks. Instead, they have fine light gray edges. A whitish line over the eye can also be found on the striated fieldwren. Striated fieldwrens can be difficult to spot as they forage quietly in thick vegetation or on the ground. If approached, the bird’s tail will elevate and sometimes move side to side, while continuing its song until it feels trapped, then it will fly away and relocate. Sounds and vocal behavior During the springtime, the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tawny Grassbird
The tawny grassbird (''Cincloramphus timoriensis'') is a large songbird that is part of the grass- and bush-warbler family (Locustellidae) commonly found in grassland and reedbed habitats. It is streaked above and has a distinctive rich brown cap. Its underside is paler and it has a long graduated tail. They call often with "loud, grumpy churring calls and a longer call that starts ''tick-tick-tick-tick'' and ends with an explosive descending trill". The tawny grassbird has 10 identified sub-species found in Australia, Indonesia, Papua New Guinea and the Philippines. Taxonomy The family ''Locustellidae'' was named by Bonaparte in 1854 and is derived from the genus name ''Locustella'' named by Kemp in 1829. The term "grassbird" was used by Gould during the mid 19th century to signify a strong correlation to long grass habitats. The tawny grassbird has also been known as tawny sphenoeacus, grassbird, tawny or rufous-capped marshbird, rufous-capped grass-warbler and rufous-cappe ...

The Australian Bird Guide
''The Australian Bird Guide'' (The Guide) was published by CSIRO Publishing in 2017. Written by Peter Menkhorst along with Danny Rogers and Rohan Clarke and illustrations by Jeff Davies, Peter Marsack and Kim Franklin, the book took almost eight years to produce. It includes 936 birds including 160 vagrants and information on the evolution and classification of birds. Upon its release, the book was praised for its comprehensiveness, images, and text detail, however, the index and measurements were criticised. A compact version of the guide was also released in 2022. Description The foreword to ''The Australian Bird Guide'' was written by Paul Sullivan, Chief Executive of Birdlife Australia, Australia's peak ornithological body. This foreword states that the authors and artists of this book are considered leaders in their field and that the details of species and sub-species is a first for Australian birds. It also describes how the maps are derived from data collected by thou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locustellidae
Locustellidae is a newly recognized family of small insectivorous songbirds ("warblers"), formerly placed in the Old World warbler "wastebin" family. It contains the grass warblers, grassbirds, and the ''Bradypterus'' "bush warblers". These birds occur mainly in Eurasia, Africa, and the Australian region. The family name is sometimes given as Megaluridae, but Locustellidae has priority. The species are smallish birds with tails that are usually long and pointed; the scientific name of the genus ''Megalurus'' in fact means "the large-tailed one" in plain English. They are less wren-like than the typical shrub-warblers (''Cettia''), but they are similarly drab brownish or buffy all over. They tend to be larger and slimmer than ''Cettia'' though, and many have bold dark streaks on wings and/or underside. Most live in scrubland and frequently hunt food by clambering through thick tangled growth or pursuing it on the ground; they are perhaps the most terrestrial of the "warblers". Ve ...
