A total of 77 species from 34 families was recorded from 11,863 observations from November 2012 to April 2013 (six months) within Universiti Malaysia Sarawak (UNIMAS) campus using line transect method. This bird list is dominated by Asian Glossy Starling (Aplonis panayensis) with 4,917 observations (41.45%) followed by Eurasian Tree Sparrow (Passer montanus) with 867 observations (7.31%) and Yellow-vented Bulbul (Pycnonotus goiavier) with 752 observations (6.34%). This study reports higher diversity (H’ = 2.5) compared to previous studies. Density of bird was estimated at 6.24 individuals/ha. In order to explore the interspecific interactions between species, 19 bird species with (1,189 observations) most observations were subjected to bipartite network analysis. Based on the network analysis it appears that birds partition food resources spatially and by food type. The highest niche overlap occurs between foraging technique (0.61) while lower overlap was observed for height (0.44), types of food (0.42) and foraging substrate (0.42). This suggests that birds were exploiting similar resources but segregated spatially. Therefore birds are partitioning their niche to allow coexistence and to adapt to human modified landscape. This study has provided valuable information in characterising the assemblage and understanding the distribution of the birds in a campus landscape.

Abstract. Izzati U, Hasibuan HS. 2019. Riparian tree and bird diversity in Cisadane River, South Tangerang City, Indonesia. Biodiversitas 20: 595-603. Riparian is a riverbank area that has unique characteristics. It is a combination of terrestrial with aquatic habitats so that riparian ecosystems have high biodiversity values. Riparian is included in a protected area that is naturally designated for vegetation, but in reality, riparian areas, especially in urban areas, have a lot of conversion of land functions by humans so that it can disrupt diversity of tree and bird species. This study aims to identify the diversity of tree and bird species and the correlation between the two. Riparian length of Cisadane River, South Tangerang City is 20.15 km. The method used was plot line with size of 20 m x 20 m for tree data and line transect for bird data by systematic sampling with a random start then analyzed using Shannon Wiener index. The results obtained were found 22 tree species included in 11 families with species diversity index (H') of 2.707 and 40 bird species belonging to 25 families with species diversity index (H') of 2.794. The diversity of tree and bird species is classified as medium. The results of the analysis using the Pearson correlation between the diversity of tree with bird species obtained that there was no relationship between the two. Based on these results, riparian zones in urban areas need to be maintained and improved in quality so that the diversity of tree and bird species increases so as to create a stable ecosystem.

Lowland Forest at the complex of Bulusaraung mountain  in the Bantimurung Bulusaraung National Park is one of important habitat of birds in South Sulawesi. This study aimed to identify bird’s diversity in the Lowland Forest of Bantimurung Bulusaraung National Park for ecotourism purposes. This research was carried out for 2 months between April and May 2018. The data were gathered by using line transect method. The data were analyzed by using Shannon-Weiner diversity index, Evenness index, Margalef species richness index, and Sorensen Similarity index. The result of the study showed that, there were 23 species of birds found in the three lines of observation tracks. There were 19 species  found in Balleanging, 12 species  in Kattokaddaro and 15 species  found in Tompobulu.The highest value of bird diversity index was found in Tompobulu (H '= 1,73) followed by Balleanging (H' = 1,54) and Kattokaddaro routes (H '= 1,43). Therefore, the diversity of bird species in the three observation pathways can be used as objects and attractions in the development of ecotourism based on bird watching in wildlife conservation efforts.

Abstract Lower mountain forest in the complex of Mount Bulusaraung Bantimurung Bulusaraung National Park, is a one of bird’s habitat in the South Sulawesi. This area is a tourist destination, especially mountain climbing activities. Thus, it is necessary to know the diversity of animals, especially birds on this hiking trail, so that the information can be used to support ecotourism activities. This study aims to analyze the diversity of bird species in the complex of Bulusaraung Mountain, Bantimurung Bulusaraung National Park in order to support ecotourism activities. This research was conducted from April to June 2018. Data was collected using the line transect method on three lines, namely the Balleanging, Kattokaddaro and Tompobulu lines. The second and third paths are hiking trails, while the rest are trails leading to community agricultural areas. The geographical position of the transect line was recorded using GPS. The GIS method was used to generate a bird watching trail map. Data analysis was carried out to calculate the individual density and frequency of bird presence. In addition, the species diversity indices, species evenness indices, and species richness indices were also calculated. The results showed that there were 44 species of birds found in the study area, which were 16 species in the Balleanging line, 27 species in the Kattokaddaro line and 37 species in the Tompobulu line. The highest bird species diversity indices value was found on the Tompobulu line (H' = 2.93), while on the Kattokaddaro line it was H' = 2.73 and the Balleanging H' = 2.55. The results of this study will support the management strategy in Bantimurung Bulusaraung National Park in order to harmonize the conservation of biological resources through ecotourism activities that involve local communities to increase their economic income.

Abstract To determine the conservation status and population structure of avian species living in various subtropical broadleaved urban forests, namely Dob Ghar, Kamal Khan, Kityari, Palamar, Seya Sar and Shahabad of Pakistan, we aimed to use the distance sampling line transect process. To avoid double counting of the same bird individual, a total of 180 counting points were set at 250 m from each other. In all, between December 2017 and November 2018, 2,879 individuals representing 53 species, 28 families and 9 orders were detected. One species was vulnerable (VU) out of 53 bird species, while the remaining 52 species were the least concerned (LC). In particular, the results of the distance analysis indicate that, in six subtropical broad-leaved forests, the bird population can vary. For eg, Palamar (0.954 ± 0.221 birds/ha) and Kityari (0.938 ± 0.162 birds/ha) were densely populated by bird species, while Kamal Khan (0.102 ± 0.178 birds/ha) was less concerm. Similarly, the CAP findings showed that bird species in Dob Ghar were more diverse (H’ = 33.92 ± 1.368) and equally distributed (E = 0.9657 ± 0.004) and that the Shahabad ecosystem was rich in bird species (R1 = 8.007 ± 0.053) compared to other habitats. In addition, the length of the twigs and topological changes in the dendrogram have shown that bird diversity may vary from habitat to habitat. The bird species were classified into eight foraging guilds. Insectivores were the most abundant bird species using all habitats in abundance. By cons, Carnivore/Piscivore/Insectivore averted to use the forest habitats Dob Ghar and Frugivore Kamal Khan and Dob Ghar. The findings of this study revealed that broad-leaved subtropical urban forests are home to a wide range of avian species. However, habitat selection among bird species varied across habitats according to vegetation structure and composition, food resources, adjoining habitats, and human settlements.

Bird Watching

Birds are important indicators to determine the quality of habitat. They played an important role in maintaining the balance of our ecosystem. This study aims to determine the species of birds and its diversity within the Central Mindanao University main campus. A line transect method combined with bird watching technique were used within the two month avian survey. A  total  of  27 species belonging to 21  families were  recorded namely, Accipitridae, Alcedinidae, Apodidae, Ardeidae, Artamidae, Bucesotidae, Campephagidae, Columbidae, Corvidae, Dicaeidae, Estrildidae, Hirundiniidae, Laniidae, Meropidae, Nectariniidae, Phasianidae, Pycnonotidae, Sturnidae and Sylviidae. Out of the 27 bird species observed, 18 resident, 3 resident-migrant, 5 Philippine endemic and 1 island endemic. The most observed species are Euarasian Tree Sparrow (Passer montanus) and followed by an introduced species which was Feral Pigeon (Columba livia). Most of the species observed were commonly found in urban communities, agroecosystem and along the forest edge. Some species of birds belonging to family Nictariniidae and Dicaeidae are associated in areas with flowering trees and there are seldom observed in other points. The average diversity of all points H’= 0.94 which is quiet low and it requires more sampling effort and other technique to record silent or shy species.

Birds play a crucial role in many food webs of aquatic ecosystem and the birds are known as good ‘bio-indicators’ as they are very sensitive to minor environmental changes. The present study was carried out in Purbasthali bird sanctuary of West Bengal (India) and its surroundings from January 2016 to December 2016 to explore the current status and diversity of avian fauna. The point count and line transect methods were implemented in bird counting. A total of 86 species of birds belonging to 31 families were recorded from the study area. Anatidae and Ardeidae were the dominant families with highest relative diversity. Residential status, IUCN Red list status and Relative abundance of bird species were also considered. Different diversity indices were also calculated. Purbasthali bird sanctuary supports a huge amount of bird diversity. So continuous monitoring of avian fauna and health condition of the ecosystem by local or state levels on taking integrated management programs will helpful to maintain a sustainable development of the habitat.

Quality degradation, modification, and habitat loss are significant threats to bird species. The natural habitat of birds has been modified into residential land and facilities to meet the needs of human life as happened at Tanjungpura University. This study aims to determine of birds species at Tanjungpura University. Observations were carried out from January to March 2019. The method used in collecting the data from bird was “Encounter rates” which was conducted in the morning starting at 6 – 9 am and at 3 - 6 pm. The data obtained were analyzed with the formula of simple abundance scale and frequency of attendance. The birds found at Universitas Tanjungpura are 28 species classified into 23 genera, 17 families, and seven orders. Birds found to have an abundance order scale are classified into abundant, general, frequent and, unusual categories. Birds included in the abundant category are Collocalia fuciphaga and Passer montanus. The types of bird foods at Tanjungpura University consist of frugivore, insectivore, granivore, herbivore, carnivore, piscivore, omnivore, molluscivore, and nectarivore. The value of attendance frequency have range between 10-100%. The bird species with highest frequency of attendance’s value is Passer montanus, Pycnonotus aurigaster, Pycnonotus goiavier, Collocalia fuciphaga, and Anthreptes malacensis.

Abstract Characterizing the diversity and structure of host-parasite communities is crucial to understanding their eco-evolutionary dynamics. Malaria and related haemosporidian parasites are responsible for fitness loss and mortality in bird species worldwide. However, despite exhibiting the greatest ornithological biodiversity, avian haemosporidians from Neotropical regions are quite unexplored. Here, we analyse the genetic diversity of bird haemosporidian parasites (Plasmodium and Haemoproteus) in 1,336 individuals belonging to 206 bird species to explore for differences in diversity of parasite lineages and bird species across five well-differentiated Peruvian ecoregions. We detected 70 different haemosporidian lineages infecting 74 bird species. We showed that 25 out of the 70 haplotypes had not been previously recorded. Moreover, we also identified 81 new host – parasite interactions representing new host records for these haemosporidian parasites. Our outcomes revealed that the effective diversity (as well as the richness, abundance, and Shannon-Weaver index) for both birds and parasite lineages was higher in Amazon basin ecoregions. Furthermore, we also showed that ecoregions with greater diversity of bird species also had high parasite richness, hence suggesting that host community is crucial in explaining parasite richness. Generalist parasites were found in ecoregions with lower bird diversity, implying that the abundance and richness of hosts may shape the exploitation strategy followed by haemosporidian parasites. These outcomes reveal that Neotropical region is a major reservoir of unidentified haemosporidian lineages. Further studies analysing host distribution and specificity of these parasites in the tropics will provide important knowledge about phylogenetic relationships, phylogeography, and patterns of evolution and distribution of haemosporidian parasites.
