"Situ Tujuh Muara sangat rawan mengalami pencemaran dan berubah alih fungsi lahan, sehingga cepatnya peningkatan jumlah penduduk dapat menyebabkan tidak seimbangnya aktivitas manusia dengan kondisi lingkungan sekitar. Beragam jenis burung dapat menjadi faktor penting untuk mengetahui keanekaragaman hayati yang dapat dijadikan sebagai usaha perencanaan dan pembangunan wilayah Situ Tujuh Muara menuju lebih baik. Tujuan dari penelitian ini yaitu menganalisis tingkat keanekaragaman, dominansi, dan kemerataan persebaran jenis burung di setiap tipe tutupan vegetasi pada Situ Tujuh Muara. Serta, menganalisis tingkat penggunaan habitat dan hubungan antara nilai keanekaragaman burung dengan tipe tutupan vegetasi di Situ Tujuh Muara. Metode yang digunakan adalah point count untuk pengamatan burung dan sampling purposive untuk menentukan titik pengamatan. Selain itu, analisis data hasil pengamatan menggunakan Indeks Shannon-Wiener, Indeks Dominansi Simpson, Indeks Kemerataan, Nilai Tingkat Penggunaan Habitat, dan Uji Kruskal Wallis. Hasil yang didapatkan pada penelitian ini yaitu nilai Indeks Keanekaragaman burung pada tipe tutupan vegetasi tinggi, sedang, dan rendah berturut-turut yaitu 1,56; 2,06; dan 2,11. Nilai Indeks Dominansi burung pada tipe tutupan vegetasi tinggi, sedang, dan rendah yaitu bernilai 0,26; 0,14; dan 0,11. Nilai tersebut menunjukkan bahwa tidak ada burung yang mendominansi pada setiap tipe tutupan vegetasi di Situ Tujuh Muara. Nilai Indeks Kemerataan burung pada tipe tutupan vegetasi tinggi, sedang, dan rendah yaitu bernilai 0,59; 0,76; dan 0,78. Nilai tersebut menunjukkan bahwa tingkat kemerataan persebaran burung pada setiap tipe tutupan vegetasi cukup tersebar merata. Nilai Tingkat penggunaan habitat pada tipe tutupan vegetasi rendah dan sedang bernilai 78,90%, serta pada tipe tutupan vegetasi tinggi bernilai 73,70%. Nilai tersebut menunjukkan bahwa tingkat penggunaan habitat pada setiap tipe tutupan vegetasi digunakan cukup baik oleh beragam jenis burung. Berdasarkan Uji Kruskal Wallis menunjukkan hasil 0,066 yaitu tidak adanya perbedaan antara keanekaragaman burung dengan tipe tutupan vegetasi. Hal tersebut membuktikan bahwa tidak ada hubungan antara keanekaragaman burung dengan tiga tipe tutupan vegetasi di Situ Tujuh Muara, Pamulang, Tangerang Selatan.

Situ Tujuh Muara is very prone to pollution and changes in land use, so that the rapid increase in population can cause an imbalance between human activities and environmental conditions. Various types of birds can be an important factor to determine biodiversity which can be used as an effort to plan and develop the Situ Tujuh Muara area for the better. The purpose of this study was to analyze the level of diversity, dominance, and even distribution of bird species in each type of vegetation cover at Situ Tujuh Muara. Also, analyze the level of habitat use and the relationship between the value of bird diversity and the type of vegetation cover in Situ Tujuh Muara. The method used is point count for bird observation and purposive sampling to determine the point of observation. In addition, the analysis of observational data used the Shannon-Wiener Index, Simpson's Dominance Index, Evenness Index, Habitat Use Rate Value, and Kruskal Wallis Test. The results obtained in this study are the value of the Bird Diversity Index in the high, medium, and low vegetation cover types, respectively 1.56; 2.06; and 2.11. The value of the dominance index of birds in the type of vegetation cover is high, medium, and low, which is 0.26; 0.14; and 0.11. This value indicates that there are no birds that dominate in any type of vegetation cover in Situ Tujuh Muara. The evenness index value of birds in high, medium, and low vegetation cover types is 0.59; 0.76; and 0.78. This value indicates that the level of even distribution of birds in each type of vegetation cover is quite evenly distributed. Value The level of habitat use in the low and medium vegetation cover types is 78.90%, and the high vegetation cover type is 73.70%. This value indicates that the level of habitat use for each type of vegetation cover is used quite well by various types of birds. Based on the Kruskal Wallis test, the result is 0.066, that is, there is no difference between bird diversity and the type of vegetation cover. This proves that there is no relationship between bird diversity and the three types of vegetation cover in Situ Tujuh Muara, Pamulang, Tangerang Selatan."

"Penelitian tentang komunitas burung di kawasan penyangga Taman Nasional Ujung Kulon TNUK bertujuan untuk menjelaskan komposisi burung pada berbagai struktur vegetasi kawasan penyangga TNUK, serta menjelaskan hubungan antara komposisi burung dengan struktur vegetasi kawasan penyangga TNUK. Kondisi kawasan penyangga di sekitar TNUK didominasi oleh area perkebunan dan pertanian yang memiliki jenis vegetasi beraneka ragam. Metode pengamatan burung yang digunakan adalah metode titik hitung. Terdapat 22 titik sampel pada pengamatan yang terbagi menjadi tiga kelompok, yaitu kawasan penyangga berjarak dekat 0-500 meter, sedang 500-1000 meter dan jauh >1000 meter.
Hasil penelitian menunjukkan masing-masing kelompok kawasan penyangga memiliki struktur vegetasi yang berbeda, namun kawasan penyangga dekat dan sedang cenderung memiliki kemiripan karena hasil scatter plot Principal Component Analysis kedua kawasan saling tumpang tindih. Nilai keanekaragaman burung tertinggi terdapat pada kelompok kawasan penyangga berjarak dekat dengan Taman Nasional, namun hasil uji t Hutcheson ketiga lokasi menunjukkan nilai yang tidak berbeda nyata. Burung tipe insektivor dan nektarivor memiliki korelasi negatif dengan DBH pohon kelapa, burung tipe granivor dan omnivor memiliki korelasi positif dengan persentase kematangan buah kelapa.

Research on bird communities in buffer zone of Ujung Kulon National Park TNUK to explain bird composition on various vegetation structures of TNUK buffer zone, and to explain the relationship between bird structure and vegetation structure of buffer zone of TNUK. The condition of buffer zone around TNUK is dominated by plantation and agriculture area which have varieties of vegetation type. Bird observation method used is the method of calculating point. There are 22 sample points on the observation that are divided into three groups, namely near buffer area 0 500 meters, medium 500 1000 meters and far 1000 meters.
The results showed that each group of buffer zones had different vegetation structures, but the nearest and the nearest buffer areas were affected by the scatter plots. The Main Components Analysis of the two regions overlapped. The value of immortal bird diversity in the buffer group is close to the National Park, but the result of the Hutcheson site t test shows no significant difference. Insektivor and nectarivor birds have a negative reputation with coconut tree DBH, granivor and omnivor species have a positive reputation with coconut maturity percentage.

"The natural world contains a huge amount of constantly changing information. Limitations on, and specializations within, sensory systems mean that each species receives only a small part of that information. In essence, information is filtered by sensory systems. Sensory ecology aims to understand the nature and functions of those filters for each species and sensory system. Fluxes of information, and the perceptual challenges posed by different natural environments, are so large that sensory and behavioural specializations have been inevitable. There have been many trade-offs in the evolution of sensory capacities, and trade-offs and complementarity between different sensory capacities within species. Many behavioural tasks may have influenced the evolution of sensory capacities in birds, but the principal drivers have been associated with just two tasksforaging and predator detection. The key task is the control of the position and timing of the approach of the bill towards a target. Other tasks, such as locomotion and reproduction, are achieved within the requirements of foraging and predator detection. Information thatguides behaviours may often be sparse and partial and key behaviours may only be possible because of cognitive abilities which allow adequate interpretation of partial information. Human modifications of natural environments present perceptual challenges that cannot always be met by the information available to particular birds. Mitigations of the negative effects of human intrusions into natural environments must take account of the sensory ecology of the affected species. Effects of environmental changes cannot be understood sufficiently by viewing them through the filters of human sensory systems."

"ABSTRACT
Jalak putih Acridotheres melanopterus merupakan burung endemik yang tersebar di daerah Jawa, Bali dan Lombok. Karena maraknya kasus perdagangan burung kicau, saat ini Jalak Putih telah termasuk dalam kategori Critically Endangered menurut IUCN. Pada habitatnya khususnya di daerah savana Bekol, Jalak Putih menempati relung tetentu. Selain Jalak Putih, teramati burung lain yang menempati habitat yang sama. Burung-burung yang menempati suatu habitat yang sama tentunya berbagi relung sebagai salah satu cara untuk menghindari kompetisi antar jenis. Oleh sebab itu, penelitian ini bertujuan untuk mengetahui pembagian relung antara Jalak putih dan jenis burung lainnya. Penelitian ini dilaksanakan di 6 area yang ditentukan pada daerah di sekitar savana Bekol, Taman Nasional Baluran, Jawa Timur, pada 16 April hingga 23 Mei 2018. Penelitian dilakukan menggunakan metode jelajah bebas dengan mengunjungi tempat dan waktu yang berbeda setiap harinya. Penggunaan habitat Jalak Putih paling besar yaitu di pohon Pilang Acacia leucopholea sebanyak 27 kali perjumpaan dan Rusa Timor Cervus Timorensis sebanyak 10 kali perjumpaan. Teramati ada dua jenis burung yang kemungkinan berbagi relung dengan Jalak Putih yaitu Srigunting Hitam Dicrurus macrocercus dengan tingkat tumpang tindih relung 0,93 dan Kerak Kerbau Acridotheres javanicus dengan tingkat tumpang tindih relung 0,70. Hasil tersebut menunjukkan bahwa kedua spesies terbukti memiliki nilai tumpang tindih relung yang cukup besar yang kemungkinan disebabkan oleh kesamaan sumber pakan atau adanya interaksi interspesifik, diantara lain yaitu kompetisi atau simbiosis yang terjadi diantara burung tersebut. Jalak putih berbagi sumber daya dengan cara pengambilan pakan yaitu dengan cara probing dan penggunaan sumber daya di waktu dan tempat yang berbeda.

ABSTRACT
Black Winged Myna Acridotheres melanopterus is one of endemic species which distribute at Java, Bali and Lombok. Black Winged Myna is one of endangered species and categorized to Critically Endangered according to IUCN because of song bird trade crisis. Black Winged Myna lived at their habitat especially at Bekol savannah at their certain niche. Birds that lived at same habitats, usually part their niche to avoid competition among species. Therefore this study supposed to knows about niche partitioning and niche overlap between Black Winged Myna and another bird species. This study was conducted at six area which is determined before at Bekol savannah, Baluran National Park, East Java. Study held from April 16th to May 23rd 2018. Method that use for observation and study is encounter survey, we visited different area and different time for each day. Black Winged Myna rsquo s habitat use mostly found at Pilang tree Acacia leucopholea with 27 encounter and Deer Cervus Timorensis with 10 encounter. We found two bird species which is mostly found at same habitat or interact each other, probably part their niche at their habitats with Black Winged Myna. The bird species is Black Drongo Dicrurus macrocercus with 0,93 niche overlap. and Javan Myna Acridotheres javanicus with 0,70 niche overlap. The result represent that those two species have high niche overlap value. That can be happens probably because of same food resource or any interspecific interaction, which is competition or symbiosis among those bird. Black Winged Myna share their resource with difference their way to take the food, which is probing and difference their foraging time and place. "
