Distribution, Ecology and Conversation
Limited spread eagle on the island of Java, from the west (Park is home) to the eastern end of the peninsula Blambangan Purwo. However, distribution is now limited in the area of primary forest and wooded hills in the area at the turn of the low plains to the mountains. Some found in the southern part of the island of Java. Presumably these birds live that specializes in the incline.
Java falcon as the rainforest is always green, lowland, and in places higher. Starting from the area close to the beach as in Ujung Kulon and Meru Betiri, to the forests and mountains with a height of 2200 meters and sometimes 3000 meters above sea level.
In general live eagle Java difficult to achieve, though not always far from human activity. Presumably this bird is highly dependent on the existence of primary forest as a place of life. Although the eagle was found that the use of secondary forests as hunting and nesting, but is close to the primary forest.
Birds of prey that hunt from perches high in the trees in the forest. With quick and agile attack victims various branches of trees or on the ground that, as a variety of reptiles, birds similar Walik, pigeons, and even chicken. Also small mammals such as squirrels secondary and squirrels, bats, raccoons, monkeys children.
Spawning period recorded from January to June. Nest set high pile of leafy twigs, made in branches high above the ground 20-30. Eggs from the point, which was incubated for approximately 47 days.
Nest tree is kind of tall forest trees, such as Rasamala (Altingia excelsa), pairs (Lithocarpus sundaicus), tusam (Pinus), flowers (Schima wallichii), and ki sireum (Eugenia clavimyrtus). Not always deep in the forest, only a few nests found 200-300 m from the recreation.
Habitat, spread eagle rare Java. So even though the share of the total area is only about 137 to 188 pairs of birds, or the estimated number of individuals ranged from 600 to 1000 tail hawks. small populations face the greatest threat to sustainability, because of habitat loss and exploitation genre. Illegal logging and forest conversion into agricultural land has reduced the primary forest cover in Java. Meanwhile, the eagles continue to be hunted for trade on the black market as pets. Because of its scarcity, the birds seemed to defend the pride, and in turn make this bird soaring prices.
Given the small population, limited distribution and high pressure faced by the district, the global conservation organization IUCN including Java eagle into the status of EN (Endangered, threatened). Similarly, the Government of Malaysia to set as protected by law.
