Abstract

The majority of wild orangutans are found outside of the protected areas, including in coal mining areas which generally overlapping with orangutan habitat. Thereby, mining ensured a direct impact on orangutans. Opportunities orangutans to survive in the mining area depends on various factors, one of them is the ability of orangutan to adapt to habitat change. We investigated habitat characteristics in the coal mining area consist of land cover types, species composition, and the structure of vegetation. Data were collected from April to September 2014 in the coal mining rehabilitation area (CMRA) of PT KPC in East Kutai. Mining caused the natural habitat fragmented into smaller patches in the form of CMRA and natural forests remaining. The forest stand in CMRA compiled by the small trees of the same species and age class. It caused the canopy is not always continue. Food trees and nest trees were limited in CMRA. Exotic species dominated in CMRA, namely: Senna siamea, Falcataria moluccana, and Senna surattensis. CMRA is not the good habitat for orangutan if seen from the aspect of either structure or vegetation composition. The quality of habitat can be improved by modifying the structure and vegetation composition, build the ecosystem corridors, increase public awareness, and involve various stakeholders at the landscape level.

Abstract

A guild is a group of species that have similar requirements of resource and foraging behavior. The knowledge of insectivorous guild could explain foraging patterns, niche exploitation, and competition in a tropical forest. This information could help to monitor the forest by understanding the guild composition and their response to the habitat condition. In order to describe the guild composition and niche overlap of insectivorous birds, we observed all of the individual birds found foraging in the evergreen forest, Baluran National Park. Bray-Curtis similarity index and Pianka niche overlap index were used to analyze the data and grouping the birds into a guild. The cluster analysis consists of 27 bird species revealed 4 guilds: ground gleaner, foliage gleaner, aerial sallier, and bark prober. Based on species richness, foliage gleaner dominates the other groups while bark prober had the least species richness in the evergreen forest. The scarcities of feeding substrate affect guild existence and proved that the diversity of habitat substrate could affect the diversity of guild in an area. Ten congeneric species were found in this habitat and most of them are grouped into foliage gleaner. The junglefowl has the highest niche overlap than any other congeneric species. It seemed that the more specific the foraging substrate niche, the higher the competition among sympatric species. The level of congeneric/sympatric species competition could become the indicator to monitor a specific habitat or forest by understanding their niche partitioning, especially if the species is protected by the law.

Abstract

Green open spaces can be potential habitats for birds in urban landscapes. Due to high number of land development, the green open spaces in urban landscapes tend to be small and scattered. Indeed, analysis about effectivity of green open spaces as bird habitats in Bogor City and its surroundings is needed. We investigated bird habitat patches on 14 locations in Bogor City and its surroundings. This study aimed to analyze the effectiveness of bird habitat patches for bird species richness using two variables (size and complexity). The data were analyzed using the Pearson Correlation and multiple linear regression. The results showed that there were no significant differences between bird species richness and size of patches. Conversely, there were significant differences between bird species richness and complexity of patches. The Pearson Correlation revealed that there were high correlation between bird species richness and complexity of patches. Finally, we propose three recommendations of green open spaces as bird habitat patches in Bogor City and its surroundings, such as protecting and managing both small and large bird habitat patches, increasing number of vegetation strata and number of vegetation in some strata in small bird habitat patches, and increasing number of vegetation in some strata in large bird habitat patch with low bird speciess richness.

Abstract

Birds of prey are one of environmental changes indicators because of their position as top predator. Many of them are migratory species that migrate from northern hemisphere to southern hemisphere, and use Rupat Island (in Riau Province) as stopover habitat. One of them is Oriental Honey Buzzard (Pernis ptilorhynchus) whose satellite tracking information (from 2006-2009) are available. This study aimed at identifying distribution characteristics of stopover habitats of Oriental Honey-buzzard in Rupat Island based on satellite tracking data using geographic information system (GIS). Several environmental variables (i.e. slope, elevation, land cover) were processed into distance to the nearest map and analyzed using logistic regression analysis. The result showed that distribution of stopover habitats covered 1 276.67 km2 (87%) of totally Rupat Island (1 461.95 km2). This distribution was mostly influenced by food availability and thermal wind. Identification of these habitat characteristics provides a baseline data for managing their stopover habitats and ecologically-based development of Rupat Island. Keywords: Logistic Regretion, Pernis ptilorhynchus, Rupat Island, Sattelite-tracking, Stopover habitat characteristic

Abstract

The study of birds using mist nets in Indonesia is still small, but this method is good enough to see how the structure of a type of bird. A study of Eurasian Sparrow (Passer montanus) in IPB Darmaga Campus expected to provide information updates on community structure and see this type of variation in body weight in the different seasons. The study was conducted at the end of the rainy season and the beginning of the rainy season in 2012 with the installation of a total of 4514 net hours. During the study 125 individuals caught Eurasian Sparrow (71 individual at the beginning of the rainy season, 56 individuals at the end of the rainy season) and 12 individuals of which the individual retrap. No difference of body weight between the beginning of the rainy season and the end of the rainy season, but there are daily variations in body weight at the end of the rainy season between morning, afternoon and evening (df = 2 , Fvalue = 5.06 , P < 0.01). Individuals in different age classes juvenile are very real in the second season (χ2 = 7.80 ,df = 1 , P < 0.01). In the adult age class, the number of individuals in the second season was not significantly different (χ2 = 0.62 , df = 1 , P > 0.05). Keyword: body weight, structure of age, beginning of the rainy season, end of the rainy season

Abstract

The Critically Endangered Cacatua sulphurea abbotti is a unique subspecies of cockatoo, endemic to a single tiny Masakambing Island in Indonesia. Data procurement on the status and distribution of their wild population is necessarily urgent in order to determine the best conservation strategy for this species. Data were collected annually from 2008-2018 by a direct roost count method in a roosting tree. Only 10 cockatoos were recorded in 2008, but the number continually increased up to 22 birds in 2018 (42.86% increase in a decade). The population was distributed in about 71% of the total size of the island, concentrated in the north-western part with a density of 1.56 (~ 2 birds/km2) in 2008 which raised up to 3.44 (~ 3 birds/km2) in 2018. The zero trapping policy enforced by the local government was probably effective in preventing the population decline, although the population is still vulnerable due to nesting failure, presumably low genetic quality and habitat destruction.

Abstract

Crescent-chested Babbler is endemic to the island of Java and Bali, Indonesia and protected by the Indonesian Government Regulation No. 7/ 1999. Its population is suspected to be declining due to ongoing habitat destruction and fragmentation. Information on its eco-biology is very poorly known. There is a need to obtain the information in order to conserve this species and its habitat. Morphometric and molt stages were recorded from 23 individuals captured by mist-nets between February and April 2016. There were variations in morphometric measurement in weight, head bill length, wing length and tail length in Cisarua Forest habitat, but no significant difference was found (F2.19 = 0.822, P> 0.05) in body weight among the three different habitats. This habitat has sufficient resource for Crescent-crested Babbler for molt activity during the study.

Abstract

Bird diversity has been known to be affected by various factors, including elevational gradient. The objective of this study was to describe the bird community trend and its associated habitat conditions on lower mountain and sub-mountain areas. The study was conducted in September-October 2017 in Gunung Halimun Salak National Park, West Java, Indonesia. Bird data were collected using point count method. Data were analyzed by using Shannon-Wiener (H’) diversity index, Margalef’s richness index (DMg), and Bray-Curtis similarity index. Birds were grouped into guilds according to their major diet. There were 54 bird species (23 families) in both altitudes, of which 23 species were found in the lower altitude and 33 species were found in the higher altitude. Contrary to most studies elsewhere, the diversity and richness indices were significantly higher at the sub mountain (H’=2.85; DMg=5.96) than at lower mountain (H'=2.38; DMg=3.79). Insectivores were dominant in both altitudes, although similarity index was low (5%). Bird diversity was higher in the higher altitude due to habitat condition. Lower montain had a higher anthropogenic disturbance than the sub-mountain.

Abstract

The bird nest adoption program in Jatimulyo is one of the activities to protect birds from extinction. This activity is carried out by keeping birds that are breeding in nests in community forest habitats. The development of this concept was expected to protect the birds and increase the economic value of the community-owned forest from the non-timber sector that supported environmental sustainability. However, the program is not yet implemented in the whole area of Jatimulyo Village. This study aimed to determine the strategy for developing the bird nest adoption program in Jatimulyo Village. Data was collected through in-depth interviews with expert respondents with extensive experience and knowledge of the studied problems. The data that has been collected was analyzed using SWOT analysis. The SWOT analysis results showed that an offensive strategy is needed to develop the bird nest adoption program, which can be carried out by utilizing strengths to seize opportunities. There are five alternative strategies, i.e. (1) increase the number of nest findings to be adopted to increase people's incomes; (2) take advantage of the attention of the government and other institutions to strengthen farmer groups and support the management of adoption programs; (3) opening access to birdwatching special interest tours by involving the community as local guides; (4) encourage bird protection in the Jatimulyo area and jointly promote bird nest adoption program; and (5) expanding the adoption area in Jatimulyo Village.
