Elegant Sunbird - Aethopyga duyvenbodei

Now, the only additions to this island is very small, they were severely fragmented population. Although they can continue to degraded habitats, and is suspected of being the subject continued decline as natural habitats are lost in the primary and secondary schools by human encroachment. They are qualified for it and threatened with extinction.

Select 12 cm. Great, brilliant color additives. Man, purple spots, red, and the coverts of the ears, a metal collar, blue and green on the crown, and ambitions over the wings - extra-coverts olive-yellow back, yellow-rumped and the lower band. Women very dull, with upper parts olive-yellow, the rump and yellow and weak. PSP similar. Brown said throat throat malacensis Anthreptes additions, and purple-brown wings and tail. It lacks the yellow rump and women. His voice is not recorded, but it requires a high degree of competence and invites the chirping song, such as congeners nearby.

It is currently known distribution of the population and duyvenbodei Aethopyga Sangihe North Sulawesi, Indonesia, despite the existence of the historical proximity Siau. In 1995, found regularly in the low density in seven locations in the period 1998-1999, and most commonly encountered species of forest on Gunung Sahendaruman, indicating a high density of population at local level. It was also found to occur in low densities in secondary habitats are isolated from primary forests, which refers to the flexibility loss1 habitats. It is, however, in the absence of large areas of the island, and the continuing loss of forest habitat in the primary and secondary schools indicate that the population continues to decline.
Find justification for investigations in the population 1998-1999 (Riley 2002) High density in primary and secondary forest habitats nearby. Also recorded a low density in the secondary habitats that were isolated from primary forests. As such, population estimates have been revised to reflect both the highest abundance of key habitats, and its presence in large areas of secondary habitats, leading to estimates of the increase 18.900 to 43.800 people.

Although the trend is unwarranted tolerance of this type of secondary habitats, and is suspected of moderate population decline continues, forest habitats are also affected by the primary and secondary education by the offense and the dispersion throughout the range. Ecology and living in primary forests, and the edge of the forest, bush and the surrounding farms (where the steel is still in the green zone and sub-floor is available) from 75 to 1,000 meters. Typically be encountered singly or in pairs, often in flocks of mixed species.

The threats of the original forest on Sangihe almost completely erased. It is now known of these species to survive in habitats of primary forests without adjacent patches1 secondary, but agricultural intensification in reducing the available area of ​​these habitats to the change. A small area of ​​remaining primary forests, which focused around the main population, and insufficient protection and continued to suffer from encroachment of agriculture on the bottom margin. Forest cover in the active volcanic island of Siau in very limited and there is off, or remain in small numbers.

Forest conservation measures under way to be saved Sahendaruman Gunung dimensions, despite the actions of a few. Since 1995, achieved a "work Sampiri" project work in the field of conservation education and development programs and ideas for future land use through agreements between the parties concerned. As a result, plans are underway for the reclassification of four "protection forest" Gunung km2 Sahengbalira as a nature reserve. Some protected forests in the valley Kentuhang as the plan for watershed hydro.

Conservation measures proposed conduct surveys to monitor population trends and to locate the remains of primary forests, to provide them protection. Meet the environmental requirements of species that can be an effective strategy to save. Ensure the effective protection of the habitat at the Gunung Sahendaruman. Proposals to support the rapid implementation of the remaining forests on Gunung Sahengbalira Strict Nature Reserve. Conservation education programs continue. Encourage forest staff to establish a permanent presence on the island.
