Deployment, Habitat and Conservation Javanese eagle.

Distribution of Javanese eagles is only limited on the island of Java, from the west end (Ujung Kulon National Park) to the eastern tip of the peninsula Blambangan purwo. But so is currently limited distribution in areas with primary forest and wooded hills where exactly on the transition to the low-lying mountain areas. Most of the Javanese eagle can be found in at least half of the hemisphere south of the island of Java. Presumably this eagle bird life cycle specializes in location.

Javanese eagles like tropical rain forest ecosystem is always green, in the lowlands or in places higher. Starting from the location near the beach like in the west end and Meru Betiri, up to the mountain forests under and above up to an altitude of 2 200 m and sometimes 3. 000 meters above sea level.

Living area typically Javanese eagle difficult to achieve, although not always far from human activities. Presumably this bird is highly dependent on the presence of primary forest as an area of his life. Although the eagle was found that utilize secondary forests as hunting and nesting area, however it is located adjacent to the vast primary forest.

The hunting of birds of prey perch area in tall trees in the forest. With a swift and agile ambush prey variety in a tree branch or on the ground that, like various types of reptiles, birds such as walik, pigeon, and even more chicken. Also the small to medium sized mammals like squirrels and squirrels, bats, raccoons, until the child monkey.

Spawning period was recorded starting in January until June. Nest-shaped pile of leafy twigs arranged high, made on a tree branch high above the ground 20-30. Eggs amounted to one point, which is incubated along approximately 47 days.

Eagles nest tree where Java is some kind of tall forest trees, like Rasamala (Latin name: Altingia excelsa), pairs (Latin name: Lithocarpus sundaicus), pine (Latin name: pine merkusii), puspa (Latin name: Schima wallichii), and ki sireum (Latin name: eugenia clavimyrtus). Not always by far is in the forest, there is also the nests are found only within 200-300 m from the recreation area.

The habitat, distribution of Java Eagles are extremely rare. Although spacious the habitat, the overall number only 137-188 pairs kuran more birds, or according to the estimated number of individuals Eagles range of about 600 to 1,000 animals. This small population facing a huge threat to the survival of sustainability, which is caused by loss of habitat as well as the type of exploitation. Illegal logging and forest conversion so make agriculture a reduction in primary forest cover in Java. In addition, the existence of Java Eagle also continue to be hunted by humans to be traded on the black market to be made in the pet. Due to its rarity, this bird preserve so as pride, and in turn make the price of this Javanese eagles soar.

Taking into account the size of the population, the location of its habitat is limited and high pressure encountered it, the IUCN World Conservation Organization enter into in the Javanese eagle en status (endangered, threatened with extinction). Thus also, the Indonesian government set as animals are protected by law.

Taxonomic or classification Javanese eagle.

Actually existence has been known since the Javanese eagle ago around 1820, when van hasselt and Kuhl collected two specimens of this bird on the location of the mountain bark to be brought to the museum leiden, Netherlands. However at that point until the end of the 19th century, this bird specimens still calculated as a type of hawk eagle.

But new in 1908, on the basis of the specimen collection Max Bartels made from sand flat, in Sukabumi in 1907, a bird expert at the German country, o. Finsch, recognizing Javanese eagle as a kind of new taxon. He believed it was a child of Spizaetus kelaarti type, a type of falcon in sri lanka. Until then in 1924, prof. Stresemann give the name of the new taxon with bartelsi Specific epithet, as an effort to honor Max Bartels above, as well include it as a child type Spizaetus nipalensis mountain eagle.

This bird is then recognized by the world scientific name is Spizaetus Nipalensis bartelsi, until later in 1953 D. Amadon had proposed to raise the ranking of Javanese eagles and put him to type in a stand-alone, ie Spizaetus bartelsi.
