Abstract Background Agroforestry is an integrated land-use system that plays a great role in the conservation of landscape biodiversity. The study aimed to assess the composition and diversity of avian species along with different habitat types of agroforestry in Kibet Town, Southern Ethiopia. Methods Four habitat types of agroforestry system which are home gardens, live fences, parkland, and eucalyptus woodlot were identified. Line transects were used for bird surveys. The Shannon diversity index (H′) and species evenness index (E) were used to compare diversity among habitat types. A similarity percentages (SIMPER) test was carried out to identify the main species and feeding guild that typified each habitat type. The overall significance was assessed with the ANOSIM test using PAST (version 4.03). Results A total of 50 bird species belonging to 28 families and 10 orders were recorded. Order Passeriformes (67.3%) had the highest number of species. Bird community composition differed among habitat types. The dissimilarity was mainly due to White-browed robin-chat (Cossypha heuglini), Streaky seed-eater (Serinus striolatus), Village Weaver (Ploceus cucullatus), African Paradise-Flycatcher (Terpsiphone viridis), and Black-Headed Paradise Flycatcher (T. rufiventer). The finding also revealed that insectivore was the dominant feeding guild. Conclusions The present study shows evidence that more insectivore bird species use different types of agroforestry as habitat and foraging sites. So, any concerned bodies who have engaged in avian conservation should give special consideration to this modified landscape.

AbstrakKawasan kampus Institut Teknologi Sumatera (ITERA) sedang mengalami perkembangan fisik yang pesat, seperti pembangunan gedung perkuliahan, laboratorium, asrama, juga embung untuk sumber air. Informasi mengenai keanekaragaman hayati di ITERA sendiri belum banyak diteliti, salah satunya adalah keanekaragaman burung. Burung merupakan hewan besar yang cukup sensitif dengan perubahan lingkungan. Penelitian ini dilakukan untuk mendapatkan data mengenai keanekaragaman burung di ITERA untuk memberikan informasi dasar. Metode yang digunakan adalah teknik point count, diterapkan pada lima stasiun utama yang dipilih berdasarkan pusat aktivitas pembangunan. Analisis yang digunakan adalah indeks keanekaragaman, kemerataan, juga kelimpahan. Selain itu, status konservasi dan tipe pakan jenis burung dianalisis menggunakan data sekunder. Hasil penelitian menunjukkan terdapat 19 jenis burung dari 16 famili. Keanekaragaman jenis burung berdasarkan indeks Shannon-Wiener tergolong sedang dan kemerataan jenis merata. Dari kategori kelimpahan yang digunakan terdapat dua jenis burung yang umum ditemukan. Bersumber pada PP No. 7 tahun 1999, terdapat empat jenis burung di ITERA yang termasuk ke dalam kategori dilindungi dan satu jenis termasuk kategori Appendix II di CITES. Feeding guild burung di ITERA didominasi tipe omnivora dan insektivora. AbstractInstitut Teknologi Sumatera (ITERA) campus area is undergoing rapid physical development, such as the construction of lecture buildings, laboratories, dormitories, as well as reservoirs for water sources. Information on biodiversity in ITERA has not much studied, one of which is bird diversity. Birds are large animals that are quite sensitive to environmental changes. This study aims to obtain data on bird diversity at ITERA to provide the baseline information. The method used is a point count technique, applied to five main stations selected based on the center of development activities. The analysis used is an index of diversity, evenness, and abundance. Besides, the conservation status and feed type of bird species were analyzed using secondary data. The results showed that there were 19 species of birds from 16 families. The Shannon-Wiener diversity index classified the bird community as a moderate, and the community evenness index was stable. From the abundance category, two types of birds commonly found. Based on PP No. 7 of 1999, there are four species of birds in ITERA, which included in the protected category and one species, including the Appendix II category in CITES. Omnivorous and insectivorous types dominate bird guild feeding in ITERA.

Shannon’S Diversity Index

In a suburb (c. 100 ha) of Ongwediva, a total of 30 breeding bird species were recorded in 2018. Shannon’s Diversity Index was 2.01. Passer domesticus comprised almost half of all breeding pairs (36.4 pairs / 10 ha). Granivores were by far the most numerous feeding guild, comprising 77.5 % of all birds breeding. Birds nesting on/in buildings were represented by two species only, but they comprised almost half (49.9 %) of all breeding birds. In comparison with other southern African towns, the number of bird species breeding in Ongwediva was low. This was compensated by high population densities of some species.

AbstractIn the Indian subcontinent there is hardly any study that compares the bird community structure of urban/suburban areas with those of forest habitat. The present survey identified diverse assemblages of birds in the Pauri district at different elevations. A total of 125 bird species belonging to 40 families including two least count species (Lophura leucomelanos and Pucrasia marcolopha) were recorded during this survey in the forest and urbanized habitats of Pauri District (Garhwal Hiamalaya) of Uttarakhand state, India. The high elevation (Pauri 1600–2100 m a.s.l.), mid elevation (Srikot-Khanda 900–1300 m a.s.l.) and low elevation (Srinagar 500–900 m a.s.l.) contributed 88.8%, 63.2% and 58.4% of the total species respectively. Rarefaction analysis and Shannon diversity index showed that the high elevation forest habitat had highest bird species richness (BSR) and bird species diversity (BSD) followed by the mid and then the low elevation forests. BSR and BSD fluctuated across seasons at all elevations but not across habitat types. Present study provides a base line data about avian community composition in urbanized and natural habitats along altitudinal gradient in the study area. This information may be useful to the conservation biologists for the better management and conservation of the avifauna in the Western Himalaya, a part of one of the hot biodiversity spots of the world.

Species diversity and composition of bird community at South Lake Wetland Park in Hohhot city were investigated from October 2013 to September 2014. In total，64 bird species belonging to 33 families and 14 orders were recorded. There are 36 summer migrant species, 15 resident species, 11 traveling species and 2 winter migrant species found. The habitats of birds were grouped into four types (wetland, woodland, grassland and residential area) according to topography and vegetation types in the survey area．Shannon-Weiner Diversity Index (H`) was 2.9450 in wetland area and 1.0768 in grassland area the highest and the lowest values, respectively. The evenness of bird species was 0.4058 lowest in woodland and 0.7581 highest in residential area. The dominance index of bird species was 0.0733 lowest in the wetland and 0.4319 highest in the woodland, respectively. This paper analyzed the relationship between the main dominant bird species and their habitat characteristics，explained the main reasons for the increased bird species number.

Forest is the most significant habitat for birds by supporting around 75% of all bird species while only 45% of all bird species have adapted to humans modified habitats. The research was conducted in the Montane Forest Research Station, Jos, Plateau State, in other to determine the abundance, diversity and effect of habitat types on bird’s species diversity. Fifteen transects of 200m were laid in the three habitat types (riparian forest, farmland and residential area) using stratified random sampling method. The data collected were analysed using R console. Shannon Weiner diversity index was used to analyse species diversity while generalized linear model was used to determine the effect of the habitat variables on bird species diversity. The result showed a total number of 1466 individual birds belonging to 17 families and 60 bird species were sighted. The abundance of birds was highest in riparian forest (2252), farmland (1732) and Residential area (1094) with no significance difference (p=0.177). Species richness was higher in the riparian forest (57), farmland (49), and the residential area (44). It also revealed that bird diversity index was highly significant. Riparian forest had the highest diversity (4.77), and the species were more evenly distributed (0.6) as compared to the other habitat types. The higher the number of trees and canopy cover the higher the diversity of species as was observed in the riparian forest where forest species that weren’t seen in the other habitats were found. The farmland and residential areas also hold a considerable number of some generalist bird species due to some patches of vegetation found in the habitat. Therefore, conservation efforts should be directed towards keeping vegetation intact in human dominated areas, as it serves as repository for bird species which are ecologically important. Hence, planting trees (economic, fruit and ornamental) should be encouraged.

Biodiversitas 20: 1753-1757.  Bird community is an important indicator of ecosystem health. A study was conducted in Gunung Tunak Nature Park to analyze the composition of bird species and the abundance and diversity of bird species. Data were collected by survey method from May to August 2017 on three trails. The bird fauna of  Gunung Tunak Nature Park consisted of 32 species belonging to 27 families and 10 orders. The order Passeriformes accounted for the dominant family and species, with an abundance of 61.6%. The species with the highest abundance is Zosterops chloris (13.9%), following by Orthotomus sepium (12.2%), and Streptopelia chinensis (10.4%). While the diversity index was 3.03, indicating that the bird community in Gunung Tunak Nature Park is still well preserved. Five species are of high conservation priority based on protected by Indonesian Law, Endemicity of Wallacea, and the IUCN Red list i.e., Megapodius reinwardt, Pitta elegans, Caloenas nicobarica, Lalage sueurii, and Dicrurus densus.

This paper presents the results of a study on the habitat preferences of selected species of the bird community in the Morgi Forest, the Kolbuszowa Forest Division (SE Poland), with the use of the point-stand bird census method. The aim of the study was to test the effectiveness of the method in determining the frequency of colonisation of stands with different habitat parameters by the most abundant bird species. In 270 tree stands of a forest complex with diverse habitats, a bird census was carried out with four counts per each stand. Next, a list of the tree stands and the bird species recorded in the stands was compiled. The stands were divided into categories according to the forest habitat type, dominant species and age class. In the next step, the occurrence frequency of the most abundant bird species was calculated for each stand category. Among the analysed species, the majority showed a positive correlation between the frequency of occurrence and habitat fertility. The influence of the dominant stand species on the occurrence frequency of bird species was largely driven by habitat fertility. The lowest average frequency of the identified avian species was found in stands dominated by pine Pinus sylvestris, birch Betula sp. and black alder Alnus glutinosa. There was generally a positive relationship between age class and the bird community parameters. It is concluded that the point-stand method of bird census provides informative results for research on the habitat selectivity of bird populations.

The paper is aimed to assessment of diversity and structure of bird community in floodplain forest ecosystem. Authors present results of analyses data on bird communities obtained at two transects in the Litovelské Pomoraví Protected Landscape Area (Czech Republic) in the period 1998–2012. Research of bird communities was carried out using the point-count method. The article deals with qualitative and quantitative representation of breeding bird species, including their relation to habitat type (closed floodplain forest, ecotone). Altogether 63 breeding species were recorded at the Vrapač transect and 67 at the Litovelské luhy transect, respectively. To be able to detect all recorded species, 11 out of 14 years of monitoring were needed at the Vrapač transect and all 8 years of monitoring at the Litovelské luhy transect, respectively. Authors show that the values in dominant bird species change significantly among the particular census dates within one season, mainly with respect to their activity and detectability. Results are discussed in the frame of sustainable forest management in floodplain forest ecosystems. The presented article can promote to discussion aimed to management strategy for floodplain forest ecosystems, which ranks among natural habitat types of Community interest protected under the Natura 2000 European network.

Tropical forests have undergone extensive transformation because of increasing tourism development, in addition to historic clearing for agricultural and cattle grazing activities. Altogether, these activities have had an important effect on bird diversity, reducing the habitat available to many species. In this study, the role of tropical forest remnants located between different land use types was evaluated for species diversity, composition, and distribution of the bird community at Akumal region in Quintana Roo, Mexico. Point counts were used to quantify the avifauna by habitat, and Shannon´s and Simpson´s diversity index were used to determine bird diversity. Additionally, bird species were classified according to seasonality and trophic guild by type of habitat. A total of 160 species and 50 families was recorded, of which 100 species were permanent residents, 47 winter visitors and 11 transients. Mature tropical forest and tropical forest remnants had higher species richness than those of modified environments. This study supports the importance of tropical forest remnants as shelters for bird species in landscapes with tourism developments, and the relevance of these remnants to maintaining high bird diversity.
