Gustav Hartlaub
Karel Johan Gustav Hartlaub (8 November 1814 – 29 November 1900) was a German physician and ornithologist. Hartlaub was born in Bremen, and studied at Bonn and Berlin before graduating in medicine at Göttingen. In 1840, he began to study and collect exotic birds, which he donated to the Bremen Natural History Museum. He described some of these species for the first time. In 1852, he set up a new journal with Jean Cabanis, the ''Journal für Ornithologie''. He wrote with Otto Finsch, ''Beitrag zur Fauna Centralpolynesiens: Ornithologie der Viti-, Samoa und Tonga- Inseln''. Halle, H. Schmidt. This 1867 work which has handcoloured lithographs was based on bird specimens collected by Eduard Heinrich Graeffe for Museum Godeffroy. A number of birds were named for him, including Hartlaub's Bustard, Hartlaub's Turaco, Hartlaub's Duck, and Hartlaub's Gull Hartlaub's gull (''Chroicocephalus hartlaubii''), also known as the king gull, it is a small gull. It was formerly sometimes cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of New South Wales
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 17 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Agriculture, Water and the Environment. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely based on a number ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collared Sparrowhawk
The collared sparrowhawk (''Accipiter cirrocephalus'') is a small, slim bird of prey in the family Accipitridae found in Australia, New Guinea and nearby smaller islands. As its name implies the collared sparrowhawk is a specialist in hunting small birds. It is characterised by its slight brow ridges and slender feet. The last segment of their middle toe projects beyond the claws of the other toes. Description The collared sparrowhawk is 29–38 cm (tail about half ), with a wingspan 55–78 cm, the average male weighs 126 g, female 218 g. They are small, fierce, finely built with rounded wings, long square tail, yellow eyes and long legs. Adults have slate-grey upper parts, sometimes with a brown wash, and a chestnut half collar. The underparts are finely barred rufous and white. The under wing and tail are finely barred. The cere is cream to olive-yellow, the eyes yellow and the legs and feet yellow. The sexes are similar in appearance but males are smaller than fema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Goshawk
The brown goshawk (''Accipiter fasciatus'') is a medium-sized bird of prey in the family Accipitridae found in Australia and surrounding islands. Description Its upperparts are grey with a chestnut collar; its underparts are mainly rufous, finely barred with white. Thus it has similar colouring to the collared sparrowhawk but is larger. The flight is fast and flexible. The body length is ; the wingspan, . Females are noticeably larger: adult males weigh , and adult females, . Distribution and habitat The brown goshawk is widespread through Australia, Wallacea, New Guinea, New Caledonia, Vanuatu and Fiji. In Australia, it is found mainly in eucalypt forests and woodlands, as well as farmland and urban areas. In the Pacific, it mainly inhabits rainforest. It was also found on Norfolk Island to about 1790, and this may be another undescribed subspecies. However, the lack of specimens from Norfolk Island (1 historical skin and 9 subfossil bones is all the material that has been ...

Australian Hobby
The Australian hobby (''Falco longipennis''), also known as the little falcon, is one of six Australian members of the family Falconidae. This predominantly diurnal bird of prey derives its name ‘''longipennis''’ from its long primary wing feathers. It occurs throughout Australia and other neighbouring countries with migrating individuals found on the islands of Indonesia and New Guinea.Debus, S. (1998). The birds of prey of Australia. Oxford University Press, Australia. Taxonomy The Australian hobby is a member of the family Falconidae and the order Falconiformes. Five major clades have been established in the genus ''Falco''. These include kestrels, merlins, hobbies, hierofalcons and peregrines. Hobbies are somewhat removed from these groups but are still a component of a more inclusive clade. Three subspecies of Australian hobby are usually recognised. These are: * ''Falco longipennis longipennis'', (Swainson, 1838) * ''Falco longipennis hanieli'' (Hellmayr, 1914) bei ...

Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known as the peregrine, and historically as the duck hawk in North America, is a Cosmopolitan distribution, cosmopolitan bird of prey (Bird of prey, raptor) in the family (biology), family Falconidae. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world, as well as the Fastest animals, fastest member of the animal kingdom. According to a ''National Geographic (U.S. TV channel), National Geographic'' TV program, the highest measured speed of a peregrine falcon is . As is typical for avivore, bird-eating raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Falcon
The brown falcon (''Falco berigora'') is a relatively large falcon native to Australia and New Guinea. A number of plumage morphs occur, with the primary distinction being between the pale morph and the dark morph. Both morphs usually have dark brown upper parts and wing coverts. Dark morph birds have predominantly dark under parts, although some light streaking is common. Pale morph birds have white underparts that are varyingly streaked with brown, sometimes heavily so. Pale individuals may also have prominently white under tail coverts and these may be diagnostic. A distinctive aspect of their behaviour is shown in the breeding season when Brown Falcons make a loud, high pitched, cackle call (like a laying hen) and screeching while in flight. The species name ''berigora'' has Aboriginal origins. Description Adults are usually long. They are found in light and dark forms and a variety of intermediates. Animals typically have red-brown heads with narrow black streaks with a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Sentinel
Sentinel species are organisms, often animals, used to detect risks to humans by providing advance warning of a danger. The terms primarily apply in the context of environmental hazards rather than those from other sources. Some animals can act as sentinels because they may be more susceptible or have greater exposure to a particular hazard than humans in the same environment.National Research Council (U.S.). Committee on Animals as Monitors of Environmental Hazards, "Animals as Sentinels of Environmental Health Hazards: Committee on Animals as Monitors of Environmental Hazards," National Academy Press: 1991, . People have long observed animals for signs of impending hazards or evidence of environmental threats. Plants and other living organisms have also been used for these purposes. Historical examples Canaries There are countless examples of environmental effects on animals that later manifested in humans. The classic example is the "canary in the coal mine". The idea o ...
