Sulawesi Masked Owl
The Sulawesi masked owl (''Tyto rosenbergii'') is a species of owl in the family Tytonidae. It is endemic to the Indonesian islands of Sulawesi, Sangihe and Peleng. It is listed by the IUCN as being of least concern. Taxonomy The Sulawesi masked owl was first described by the German ornithologist Hermann Schlegel in 1866 as ''Strix rosenbergii'', but was later included in the genus ''Tyto''. The specific name "rosenbergii" refers to the German surveyor and naturalist Hermann von Rosenberg who collected bird specimens in the East Indies and sent them to the National Museum of Natural History in Leiden to be classified. There are two subspecies, ''T. r. rosenbergii'' (Schlegel, 1866), found in Sulawesi and Sangihe, and ''T. r. pelengensis'' Neumann, 1939, found in Peleng in the Banggai Island group. Other common names for this bird include Rosenberg's owl, Rosenberg's barn-owl, Sulawesi owl, Sulawesi barn-owl, Celebes barn-owl, Celebes masked-owl and Celebes o ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Von Rosenberg
Hermann von Rosenberg (April 7, 1817 – November 15, 1888) was a German naturalist born in Darmstadt. He published a few books and several articles concerning his work in the East Indies. In these he describes the geography, zoology, linguistics and ethnography of the islands. Biography In late 1839 he enlisted in the Dutch ''Harderwijk'', and soon afterwards was stationed in the Netherlands East Indies as a military cartographer, tasked with making topographical surveys. He spent 30 years of his life working in the East Indies. From 1840 until 1856, Rosenberg was a topographical draughtsman on Sumatra and its neighboring islands. Afterwards he was a civil servant, working as a cartographer and surveyor in the Moluccas and western New Guinea. He was a member of the Etna expedition. Rosenberg had a keen interest in ornithology, and beginning in the 1860s, collected specimens in the Indies for study and classification by Hermann Schlegel at the natural history museum of Leiden ...

Birds Described In 1866
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. Bird ...

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] |
International Union For Conservation Of Nature
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 pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunung Ambang Nature Reserve
Gunung Ambang Nature Reserve is a preserved area in the north of the island of Sulawesi in Indonesia.

Pellet (ornithology)
A pellet, in ornithology, is the mass of undigested parts of a bird's food that some bird species occasionally regurgitate. The contents of a bird's pellet depend on its diet, but can include the exoskeletons of insects, indigestible plant matter, bones, fur, feathers, bills, claws, and teeth. In falconry, the pellet is called a ''casting''. The passing of pellets allows a bird to remove indigestible material from its proventriculus, or glandular stomach. In birds of prey, the regurgitation of pellets serves the bird's health in another way, by "scouring" parts of the digestive tract, including the gullet. Pellets are formed within six to ten hours of a meal in the bird's gizzard (muscular stomach). Ornithologists may collect one species' pellets over time to analyze the seasonal variation in its eating habits. One advantage of collecting pellets is that it allows for the determination of diet without the killing and dissection of the bird. Pellets are found in different locat ...

Rijksmuseum Van Natuurlijke Historie
The Rijksmuseum van Natuurlijke Historie (National Museum of Natural History) was a museum on the Rapenburg in Leiden, the Netherlands. It was founded in 1820 by Royal Decree from a merger of several existing collections. This happened on the initiative of Coenraad Jacob Temminck, who saw the museum primarily as a research institute for the University of Leiden. The total collection was already quite large at the time, and continued to grow from foreign expeditions and by obtaining private collections from inheritances. The location is currently used by the ''Rijksmuseum van Oudheden''. History The location was originally a hofje called ''Hof van Zessen''. In 1815 plans were made to build a museum there (the first building called a "museum" in Leiden). It opened in 1820, and until 1913, the museum normally opened to the public on Sundays. In 1913, the museum moved to a new building, with very little room available for exhibits, and in 1950, this room was also closed. After that, th ...

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] |
Tytonidae
Barn-owls (family Tytonidae) are one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the Strigidae in structural details relating in particular to the sternum and feet. Barn-owls are a wide-ranging family, although they are absent from northern North America, Saharan Africa, and large parts of Asia. They live in a wide range of habitats from deserts to forests, and from temperate latitudes to the tropics. Within these habitats, they live near agricultural areas with high amounts of human activity. The majority of the 20 living species of barn-owls are poorly known. Some, like the red owl, have barely been seen or studied since their discovery, in contrast to the common barn-owl, which is one of the best-known owl species in the world. However, some subspecies of the common barn-owl poss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
