Diversity and abundance of avifauna in the Suba Forest area, central Ethiopia

Birds are one of the best-described taxa, but detailed knowledge about most bird species in Ethiopia remains rare, which hinders the development and evaluation of conservation strategies in the region. In this study, we estimated bird species diversity and abundance in the Suba Forest area (comprising natural forest and adjacent plantation forest and farmland) in central Ethiopia, during the dry and wet seasons in 2021. Bird data were collected using line transects or point counts in each habitat type. Two-way ANOVA was applied to evaluate the effect of habitat and season on bird species richness and abundance. A total of 132 bird species belonging to 51 families were recorded during the study. Of these, 124 are residents, 4 are endemic to Ethiopia, 11 are endemic to Ethiopia and Eritrea, and 4 are near endemics (one largely confined to Ethiopia and the others with their core populations in Ethiopia and Eritrea). Habitat type and season both had significant effects on species abundance and richness. Species diversity was highest in natural forest during the wet season, and lowest in farmland during the dry season. Plantation forest and farmland shared similar avian communities, with both being human-altered habitats in close proximity to each other. Native forest supported the highest number of bird species, which confirms the Suba Forest area’s great potential for biodiversity conservation and sustainable wildlife tourism. Continuous monitoring of this area and effective implementation of conservation measures will provide beneficial outcomes for not only avifauna but other taxa.

Diversity and abundance of avifauna in forest research centre, Mulugu, Telangana, India

A study was conducted to document the avian diversity of the Forest Research Centre (FRC) and Forest College and Research institute (FCRI) Mulugu, Telangana, India from January 2020 to December 2020. Birds were surveyed at two different timings of the day i.e. early morning from 7am to 10 am and at evening from 3pm to 6 pm using line transect and point count method. A total of 77 species belonging to 15 orders and 42 families were recorded in which the maximum abundance of the species was recorded in the order Passeriformes. The analysis of dietary preference showed the dominance of the insectivorous community (52 %) followed by Frugivores (13%). The data on residential status revealed that all the 77 species observed, are resident in India with local migratory nature. The recorded species, Black-headed Ibis (Threskiornis melanocephalus) is listed under the near threatened (NT) category in the IUCN red data list. The work highlighted the importance of green cover around urban ecosystems as a preferred habitat for avian populations. FRC supports good bird diversity and protection and management of areas in and around them will help with conservation of the species.

Conservation status, feeding guilds, and diversity of birds in Daroji Sloth Bear Sanctuary, Karnataka, India

The present study was carried out to investigate the importance of habitat quality for the diversity, distribution, and abundance of avifauna in Daroji Sloth Bear Sanctuary, Ballari District from February 2015 to January 2016. A total number of 189 species of birds, belonging to 62 families and 18 orders were recorded during the survey. A family-wise analysis showed that the families Accipitridae (12 species), followed by Muscicapidae (11 species), Ardeidae & Alaudidae (8 species each), and Cuculidae (7 species) dominated the avifauna of the region. The residential status of birds revealed that 74% (140 species) were resident, 23% (44 species) were winter, 2% (3 species) were summer and 1% (2 species) was passage migrant’s species. The study resulted in the recording of fives globally Near Threatened category, viz, Painted Stork, Black-headed Ibis, Oriental Darter, River Tern, and Pallid Harrier; and two Vulnerable species, viz, Yellow-throated Bulbul and Woolly-necked Stork. The feeding guild analysis revealed that the insectivorous guild has the most number of recorded avian species (33%, 63 species), followed by carnivorous (31%, 58 species) and least by nectarivorous (1%, 2 species). This study provides baseline data for monitoring the avifauna in the sanctuary and demonstrates the importance of the area in bird conservation. The study also highlights the negative impact of anthropogenic activities as the main cause for the loss of diversity of both birds and their habitat and the urgent need to conserve this biodiversity-rich area with long-term monitoring programs.

The Abundance of Avifauna in an Agricultural Landscape: A Benefit of Community Conservation Initiatives in Haryana, India

Agricultural practices have the potential to negatively impact local ecosystems. Further, the clearing of native vegetation to make way for farming land could give rise to the loss of various faunal species. If properly managed, such practices have the potential to adopt a holistic approach combining agricultural produce and local species conservation. To examine such a prospective approach, the community conservation initiatives started by the agricultural village of Kanalsi, Haryana was the focus of attention. To begin with, the land use within the village and nearby areas was considered to examine the forest and agriculture dominated areas. Secondly, a survey was conducted in the month of December, 2012 to record the number of avian species present within this landscape. In total, 79 species of birds were recorded. Despite being an agriculture dominated region, the ecosystem conservation initiatives started by the local village communities had played a positive role for the protection of local avifauna.

survey. Sampling sites were established following the established transect on the terrestrial area and on the edge around the lake, with an interval of 200 m apart. A total of 67 species, 28 families and 12 orders were identified. Family Ploceidae had the highest number of bird species (nine species) followed by Charadriidae (seven species), Ardeidae and Sturnidae (five species) each and Estrildidae, Nectariniidae and Anatidae (three species) each. Species abundance and diversity varied between the two habitats. Terrestrial habitat had the high species abundance and diversity compared to aquatic habitat. Shannon's diversity index indicated that

Comparison of avifaunal diversity in and around Neora Valley National Park, West Bengal, India

Anthropogenic intervention has led to conversion of much of the global diversity by means of habitat alterations. The present study was carried out to investigate the importance of habitat quality and habitat heterogeneity for the diversity, distribution and abundance of avifauna in and around Neora Valley National Park (NVNP) during April-May 2010. A total of 73 bird species belonging to 25 families were recorded during the present study applying a modified point count method. Forest edges were found to be most diverse with a total count of 54 bird species having an abundance of 172.53 number of birds ha-1. Study areas with human settlements was represented by a total species count of 24 with an abundance of 130.39 number of birds ha-1 while a total species count of 22 with an abundance of 69.32 number of birds ha-1 was recorded from thick vegetation assemblage with close canopy cover. This site specific occurrence pattern for avifauna was reflected in the study of diversity indices. The highest Shannon-Wiener general diversity score of 3.77 was recorded for bird species from forest edges. Study areas with dense canopy closure were found to support more habitat specialist bird species while areas having human settlements harboured more opportunistic bird species. An overall negative influence of human settlements on bird diversity, distribution and abundance was evidenced from the present study and needs further investigation. Moreover, intensive studies will certainly enrich our knowledge of avian diversity and distribution pattern from the present study location.

Comparing conventional and organic olive groves in central Greece: plant and bird diversity and abundance

AbstractThe present study was conducted in Magnesia Prefecture, central Greece, during the period May–June 2007. It aimed at the comparison between conventional and certified organic olive groves with regard to olive and olive oil production, diversity of plants (herbaceous and woody) and diversity and abundance of avifauna. Correlations between variables within herbaceous plants (linear regression) and woody plants (Principal Component Analysis), and the role of integration time of olive groves to the organic system were investigated. Also, finding easily measurable parameters indicating high bird diversity levels within organic and conventional management systems was a main target of the study. According to our findings, neither edible olive yield nor olive oil yield showed significant differences between conventional and certified organic olive groves. There is an increasing trend for alpha and beta diversity of herbaceous plant species, woody plant beta diversity, density and cover of woody plants, and density of breeding birds in certified organic olive groves (10 years) in comparison with conventional ones. The effect of time since the adoption of organic procedures is very important and produces benefits for the biodiversity. In the total olive groves 15 insectivorous, six granivorous and three insectivorous/granivorous birds species were recorded. Nine bird species distinguished by Ward's hierarchical clustering were identified as typical (indicator value, IndVal>50%) of specific farming systems. Among them, the Eurasian jay, associated with the 10-year certified organic olive groves, and the common cuckoo, Orphean warbler and Red-backed shrike, associated with the 6-year certified organic olive groves, should be regarded as characteristic species (IndVal>70%). Conclusively, organic farming favors some aspects of diversity of herbaceous and woody plants of olive grove ecosystems. On the contrary, similar effects on breeding bird diversity and density were not clearly recorded. However, breeding bird density proved a good indicator of their richness.

Profil Avifauna dalam Ekosistem Urban Kota Denpasar

The objective of this survey was to estimate species richness and abundance of avifauna in several main habitats in urban ecosystem at Denpasar City. For these purposes 18 urban areas consisting of three types of habitats, i.e. mangrove forest, rice field, and city parks (including garden and shrub) were selected. The point count method was applied to observe birds with three-time observation in the respective urban area. Thirty-six species of birds were recorded and seven bird species were met once with one individual only. Based on Jackknife index, probably 43 bird species have been living in urban ecosystem at Denpasar City. There were five species belonging to common birds yellow-vented bulbul (Pycnonotus goiaver) , spotted dove (Streptophelia chinensis) , bar-winged prinia (Prinia familiaris) , scaly-breasted munia (Lonchura punctulata), and olive-backed sunbird (Nectaria jugularis) which tend to live in all types of urban areas. Variance analysis showed that both Simpson (F 2:17 =6.330;P=0.010) and Shannon-Wiener (F 2:17 =12.870;P=0.001) diversity indeces of birds in mangrove forest were significantly different from those in rice field and city park. Profil of avifauna in mangrove forest is better than that in rice field and city parks.

Distribution and abundance of avifauna on the foothills of Mt. Pangasugan, Baybay, Leyte, Philippines

This study determined the distribution and abundance of avifauna on the foothills of Mount Pangasugan using the standard transect method. A total of 46 avifaunal species belonging to 12 orders and 27 families with 24% endemism were found in the three selected sites based on habitat types, degree of disturbance and elevation range. Most represented order is Passeriformes while the most represented family is Columbidae. Patterns of distribution and abundance of avifauna tend to be associated with habitat type and degree of disturbance. The most abundant and most frequently encountered species are the generalists, which can tolerate various degree of disturbance in a wide range of habitats; the least frequently occurring and least abundant species are mostly endemic interior species which prefer relatively intact forest at higher elevations where disturbance is very minimal. These specialist groups of avifaunal species, which are mostly internationally recognized as threatened, show unique association with particular habitat type, thus considered to be highly sensitive to habitat change. Protection of the remaining forests in Mount Pangasugan is deemed necessary for the survival of these interior species.

Distribution and abundance of forest birds in Ghana

Ntiamoa-Baidu, Y., Owusu, E.H., Asamoah, S. & Owusu-Boateng, K. 2000. Distribution and abundance of forest birds in Ghana. Ostrich 71 (1 & 2): 262–268. Forest reserves within the Ghanaian rain forest have been classified into categories (Condition I-VI) on the basis of their botanical importance and status of the vegetation. We present data on the distribution and abundance of avifauna of 28 Condition II and III forest reserves in southern Ghana based on line transect counts and mist-net captures. A total of 227 species were recorded for all the sites; species records for individual sites ranged from 78–119. The dominant groups in the overall survey were Muscicapidae (represented by 40 species), Pcynonotidae (21) and Cuculidae (12). The most abundant bird species in the Ghanaian forests were Yellow-whiskered Greenbul, Green Hylia, Green Pigeon and Olive Sunbird. Species encounter rates ranged from 16.7 to 50.7 species per km with individual bird encounter rates of 27.9 to 172.0 birds per km. Capture rates in mist-nets ranged from 1.2 to 3.9 birds per 100 metre net-hr (mnh). A total of 183 species were recorded in Condition II forest as compared with 167 in Condition III forests. The effects of forest condition and vegetation types on the total number of species recorded were, however, not statistically significant. The Similarity Index for bird communities within Condition II and III forests was 0.72. Bird species composition in the two forest types also differed: e.g., seven primary forest species, as well as 40% of the species associated with primary and matured secondary forest which were recorded in Condition II forests, were absent from Condition III forests. Bird communities of Moist Evergreen, Upland Evergreen and Moist semi-Deciduous were more similar than communities in the Wet Evergreen forest type. The implication of the results for conservation of the Ghana's forests is discussed.

Effect of Streamside Management Zone Width on Avifauna Communities

Abstract We analyzed 2 yr of bird population data in streamside management zones (SMZs) of three widths (50 ft, 100 ft, and 164 ft), adjoining ≤5 yr old pine plantations, and mature riparian areas in the Georgia Upper Coastal Plain. We evaluated relationships between SMZ width and bird abundance and density. Breeding and wintering avifaunal abundance were greater in SMZs than in the surrounding pine plantation. Breeding forest interior birds and forest interior neotropical migrant species were abundant in the mature forest control, but were essentially absent in SMZs and pine plantations. However, SMZs did provide habitat for an abundant avifauna community including several interior-edge and edge species not found in the pine plantations. Avian abundance was similar among SMZ widths, although densities were highest in the narrow SMZs. Forest managers should regard SMZs as important for maintaining avifauna abundance and diversity across pine dominated landscapes. South. J. Appl. For. 19(4):166-169.
