Lesser Sooty Owl
The lesser sooty owl (''Tyto multipunctata'') is an owl that lives in the wet tropics region of Australia. It is sometimes considered conspecific with the greater sooty owl, ''Tyto tenebricosa'', by some authors. The birds are then together commonly referred to as sooty owl. Like other birds of prey, the female () is bigger than the male (). The lesser sooty owl is part of the masked group of owls: an important part of the environment because they are efficient predators that keep down rodent populations. Diet They feed mostly on animals like bandicoots and rodents such as rats Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus ''Rattus''. Other rat genera include ''Neotoma'' ( pack rats), ''Bandicota'' (bandicoot ..., but occasionally eat arboreal animals like birds and squirrel gliders. Lesser sooty owls live long and have low production rates with a breeding season ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
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 provide sc ... [...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] |
Gregory Mathews
Gregory Macalister Mathews Order of the British Empire, CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England. Life He was born in Biamble, New South Wales, Biamble in New South Wales the son of Robert H. Mathews. He was educated at The King's School, Parramatta. Mathews made his fortune in mining shares, and moved to England in 1902. In 1910 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were William Eagle Clarke, Ramsay Heatley Traquair, John Alexander Harvie-Brown and William Evans (naturalist), William Evans. Ornithology Mathews was a controversial figure in Australian ornithology. He was responsible for bringing trinomial nomenclature into local taxonomy, however he was regarded as an extreme splitter. He recognised large numbers of subspecies on scant evidence and few notes. The extinct Lord Howe Pigeon was described by Mathews in 1915, using a painting as ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Sooty Owl
The greater sooty owl (''Tyto tenebricosa'') is a medium to large owl found in south-eastern Australia, Montane rainforests of New Guinea and have been seen on Flinders Island in the Bass Strait. The lesser sooty owl (''T. multipunctata''), is sometimes considered to be conspecific with this species, in which case they are then together referred to as sooty owls. It is substantially smaller and occurs in the wet tropics region of North Queensland, Australia. Description Greater sooty owls have a finely white spotted head with scattered white spots on the wings. The females are lighter colored than the males. They appear to be the heaviest of the living species in the barn owl family, however the Tasmanian subspecies of the Australian masked owl is larger still. The females' length is and weighs . The smaller male has a length of and weighs . The wing length is 30–40 cm. The large dark eyes are set in a round large facial disk. The facial disk is dark gray-silver or ...

Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frogmouths.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Bandicoot
Bandicoots are a group of more than 20 species of small to medium-sized, terrestrial, largely nocturnal marsupial omnivores in the order Peramelemorphia. They are endemic to the Australia–New Guinea region, including the Bismarck Archipelago to the east and Seram and Halmahera to the west. Etymology The bandicoot is a member of the order Peramelemorphia, and the word "bandicoot" is often used informally to refer to any peramelemorph, such as the bilby. The term originally referred to the unrelated Indian bandicoot rat from the Telugu word ''pandikokku'' (పందికొక్కు). Characteristics Bandicoots have V-shaped faces, ending with their prominent noses similar to probosces. These noses make them, along with bilbies, similar in appearance to elephant shrews and extinct leptictids, and they are distantly related to both mammal groups. With their well-attuned snouts and sharp claws, bandicoot are fossorial diggers. They have small but fine teeth that allow ...

Rats
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus ''Rattus''. Other rat genera include ''Neotoma'' (pack rats), ''Bandicota'' (bandicoot rats) and ''Dipodomys'' (kangaroo rats). Rats are typically distinguished from mice by their size. Usually the common name of a large muroid rodent will include the word "rat", while a smaller muroid's name will include "mouse". The common terms ''rat'' and ''mouse'' are not taxonomically specific. There are 56 known species of rats in the world. Species and description The best-known rat species are the black rat (''Rattus rattus'') and the brown rat (''Rattus norvegicus''). This group, generally known as the Old World rats or true rats, originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over in the wild. The term ''rat'' is also used in the names of other small mammals that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squirrel Glider
The squirrel glider (''Petaurus norfolcensis'') is a nocturnal gliding possum. The squirrel glider is one of the wrist-winged gliders of the genus '' Petaurus''. Habitat This species' home range extends from Bordertown near the South Australian/Victorian Border through south-eastern Australia to northern Queensland. This species was thought to be extinct in South Australia since 1939 until a genetic test confirmed their inhabitance in this area. The squirrel glider lives in south-eastern Australia in the dry sclerophyll forest and woodlands. In Queensland, however, they occupy a wetter eucalypt forest. The glider will make a den in the hollow tree and line it with leaves. Here it will sleep and usually lives in groups of one male, 2 females, and offspring. Appearance Like most of the wrist-winged gliders, the squirrel glider is endemic to Australia. It is about twice the size of the related sugar glider (''P. breviceps''). Its body is 18–23 cm long and its tail measur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breeding Season
Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and changes in the predation behaviors of other species. Related sexual interest and behaviors are expressed and accepted only during this period. Female seasonal breeders will have one or more estrus cycles only when she is "in season" or fertile and receptive to mating. At other times of the year, they will be anestrus, or have a dearth of their sexual cycle. Unlike reproductive cyclicity, seasonality is described in both males and females. Male seasonal breeders may exhibit changes in testosterone levels, testes weight, and fertility depending on the time of year. Seasonal breeders are distinct from opportunistic breeders, that mate whenever the conditions of their environment become favorable, and continuous breeders that mate year-round. T ...

Tyto
''Tyto'' is a genus of birds consisting of true barn owls, grass owls and masked owls that collectively make up all the species within the subfamily Tytoninae of the barn owl family, Tytonidae. Taxonomy The genus ''Tyto'' was introduced in 1828 by the Swedish naturalist Gustaf Johan Billberg with the western barn owl as the type species. The name is from the Ancient Greek ''tutō'' meaning "owl". The barn owl (''Tyto alba'') was formerly considered to have a global distribution with around 28 subspecies. In the list of birds maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC) the barn owl is now split into four species: the western barn owl (''Tyto alba'') (10 subspecies), the American barn owl (''Tyto furcata'') (12 subspecies), the eastern barn owl (''Tyto javanica'') (7 subspecies) and the Andaman masked owl (''Tyto deroepstorffi''). This arrangement is followed here. Some support for this split was provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
