DIVERSITY AND DISTRIBUTION OF RAPTORS AT GUNUNG HALIMUN NATIONAL PARK WITH PARTICULAR REFERENCE TO JAVAN HAWK- EAGLE
Although the role of raptors as the top predators in the food chain is important to maintain the balance of an ecosystem, in Indonesia they have rarely been studied.This paper presents the most comprehensive study on the diversity and distribution of raptors with emphasize on Javan Hawk-eagle at Gunung Halimun National Park, the largest remnant forest in Java.The raptor study has been done by field surveys,long watches at selected observation sites and collecting information from previous reports.The results showed that there are 17 raptor species recorded in the area.Furthermore, the Crested Serpent eagle (Spilornis cheelo),Black Eagle (Ictinaetus malayensis), and Javan Hawk-eagle {Spizaetus bartelsi) were recorded in many locations.However,the Black-winged Kite {Elanus caeruleus), Brahminy Kite (Haliastur Indus), Lesser Fish-eagle (Ichthyophaga ichthyaetus),Japanese Sparrowhawk (Accipiter gularis) and the White-bellied sea-eagle (Haliaeetus leucogaster) were observed only in one location. In addition, the Javan Hawk-eagle was recorded at 14 locations namely G. Halimun Utara, G. Buligir Putih, Pasir Cangkuang, G. Malang, West Halimun, G. Bodas, G. Tumpeng, G. Citimur, G. Bengreng, G. Batu, Cadas Mahpar, G. Kempul, G. Kendeng and G. Botol.The number of observed Javan Hawk-eagle individuals at G. Botol was higher than in other locations
Review of The Origin and Evolution of Social Signals in Ducks; in Particular The Function of Courtship Displays
Recently, there has been an increase in the use of behavioural characteristics, especially courtship behaviour, in evolutionary studies. This is because such behaviour is thought to be of fixed pattern and species specific.In waterfowl, the study of the courtship behaviour was pioneered by Heinroth (191 1). His study has been elaborated by Lorenz (1941). Following this, Johnsgard (1962) and McKinney (1975) also have contributed much in this field of study. In the beginning, Heinroth and Lorenz used the evolution of courtship displays in waterfowl as indicators of taxonomic relationships. Then, Johnsgard investigated the distribution of homologous display repertoires of Anatidae and found out the relationships of all species. Since then, the study has been directed towards the search forfactors which have been responsible for the evolution af spec if^ differences, such as the difference in frequency, in the order of displays linked in sequences and in the degree ofelaboration of plumage features reinforcing signal movements. As examples, Johnsgard (1960a) studied the courtship displays in North American black duck (Anas nrbripes) and mallard (Anas platyrhynchos), McKinney (1970) observed four species of bluewinged ducks (Anas cyanopteta, A. discors, A. clypeata and A. smithi) and Prawiradilaga (1985) investigated the grey teal (Anas gibberifrons) and chestnut teal (Anas castanea).So far, not all of these specific factors have been brought up.It is the aim of this review to examine and discuss aspects of evolution of courtship displays which have been presented; in particular the origin and evolutioh of social signals in ducks, especially those referred to specifically as courtship displays

Role of Birds on Population Control of Destructive Insects
Approximately 331 species of birds or 67% of the total number of buds on Java island are primary and secondary insectivores. These buds were found to feed on 14 orders of insects (72%) which are potential as crop destructives. The orders of Coleoptera, Lepidoptera and of Orthoptera were eaten by more than 100 birds species. In order to promote the use of birds to control destructive- insect population, it is important to study the bio-ecology of insectivorous buds in details

Pengaruh Pemberian Bui Phaseolus Lunatus Dalam Ransum Terhadap Konsumsi Pakan Dan Pertambahan Bobot Badan Ayam Kampung
DARJONO & DEWI MALIA PRAWIRADILAGA 1987. Effect of level of Phaseolus lunatus seeds in the native chicken ration on feed consumption, and body weight gain Suppl. Berita Biologi 3 :61 -65. The experiment was aimed to obtain a basic guide of the amount of P., lunatus in chicken ration during growing period. Observation using 25 cockerels and 25 pullers, was based on Completely Randomized Design. The treatment consisted of level of P. lunatus in the ration, namely RK (as control ration), RI, RII, RIII, and RIV, containing 0%, 5%, 10%, 15%, and 20% respectively. Data was analyzed using Analysis of Variant, and the difference was tested by Honestly Significant Different Test. The results showed that the level of P. lunatus up to 20% had no significant effect (P > 0,05), on feed consumption and body weight gain during growing period. The highest feed efficiency for the cockerels was RI (0,0593) followed by RK (0,0559), RIII (0,0506), RIV (0,0478), and RII (0,0350) respectively; whereas for the pullets was RII (0,0267) followed by RK (0,0262), RI (0,0225), RIII (0,0220), and RIV (0,0102) respectively
ADDITIONAL NEW RECORDS OF BIRDS OF GUNUNG HALIMUN NATIONAL PARK BASED ON BANDING STUDIES [Rekaman Baru Burung (Tambahan) dari Taman Nasional Gunung Halimun Berdasarkan Studi Pemitaan]
MONITORING THE BIRD COMMUNITY AT G. KENDENG-GUNUNG HALIMUN NATIONAL PARK*[Pemantauan Komunitas Burung di G. Kendeng-Taman Nasional Halimun]
Untuk mengetahui dinamika komunitas burung di Taman Nasional Gunung Halimun dilakukan pemantauan setiap bulan mulai bulan Januari 2000 sampai Desember 2001.Pemantauan dilakukan di kaki G. Kendeng menggunakan metode tangkap lepas dengan jaring kabut yang dipasang di atas tanah dan pada tajuk pohon. Dalam makalah ini disampaikan hasil pengamatan dari periode kedua yang dilakukan mulai Januari sampai Desember 2001.Hasil pengamatan menunjukkan bahwa keragaman jenis burung di tajuk pohon (26 jenis) hampir sama dengan pada permukaan tanah (25 jenis). Sedangkan 12 jenis tercatat dapat dijumpai di tajuk pohon dan pada permukaan tanah.Burung yang sangat umum dijumpai adalah Cinclidium diana dan Ficedula dumetoria diikuti Arachnothera longirostra.Burung yang sangat jarang dijumpai adalah Accipiter trivirgatus Macropygia unchall, Batrachostomus cornutus, Lacedo pulcheila, Iole virescens,Enicurus leschenaulti, Tesia superciliaris, Phylloscopus trivirgatus, Abroscopus superciliaris, Seicercus grammiceps, Muscicapa daurica,Muscicapaferruginea, Arachnothera ajfinis, Anthreptes singalensis, Zosterops montanus dan Lophozoplerops javanicus
Understorey birds of Cikaniki Research Station, Gunung Halimun-Salak National Park, West Java: Report of the Indonesian Bird Banding Scheme Training Programme
This report summarises findings from the first Training of Trainers (ToT) programme of the Indonesian Bird Banding Scheme (IBBS), which took place at Cikaniki Research Station (1000- 1100 m asl), Gunung Halimun-Salak National Park, during July 2009, and compares them with the results of previous banding studies conducted at the site by PPB-LIPI staff since 1996. Over the seven days from 13 to 19 July 2009, a total of 97 individuals representing 29 species were captured, and in most cases, banded. Juvenile birds belonging to 13 species comprised 28% of all individuals captured, and early primary moult was found on 32% of adults captured, suggesting that many species had recently completed breeding. The two most frequently captured species were the Little Spiderhunter Arachnothera longirostra and the Javan Fulvetta Alcippe pyrrhoptera. A comparison with previous banding studies between 1996 and 2002 at the same site shows that the latter species was repeatedly misidentified as the Fulvous-chested Jungle Flycatcher Rhinomyias olivacea, a species otherwise unknown for the park. This finding negates the conclusions of previous reports that R. olivacea is an important component of the understorey avifauna of the park at this altitude. Nine individuals, representing six species, were recaptured during the IBBS programme, including a Sunda Forktail Enicurus velatus that was at least 9 years old when re-trapped, and a Horsfield’s Babbler Malacocincla sepiaria that was at least 8.75 years old
