Wild Fauna

With the fast depletion of area under forest cover due to various anthropogenic factors, it is important that conservation of wild fauna must be focused in human-dominated landscapes such as agroforestry systems. It important to understand the bird diversity of agroforestry systems to develop a baseline to formulate policies encouraging trees in agricultural fields. Fixed radius point counts were placed across the agroforestry systems in Ayodhya district, Uttar Pradesh to determine the diversity and distribution of birds in these systems. A total of 148 bird species belonging to 53 families and 16 orders were recorded from the study area. Passeriformes (76) had the maximum number of bird species. Omnivore (51%) was the dominant feeding guild. According to their residential status, the maximum bird species were resident (76%), followed by winter visitors (21%) and summer visitors (3%). Out of the 148 bird species recorded, eight species were in the threatened category of IUCN Red List and 28 species were rarely sighted birds. This result proves that the agroforestry systems provide a good habitat for the terrestrial as well as waterbirds thus, highlighting the conservation value of this system. Such land use types must therefore be promoted and widely practiced all across the state.

Anthropogenic Threats

Anthropogenic threats to wetland ecosystems, including discharge of industrial effluents, municipal sewerage, land reclamation, erosion and deforestation, have contributed to the rapid declines in populations of many bird species. The present study aimed to document avian diversity, including birds on the IUCN Red List, at Nangal Wetland, Punjab from February 2013 to January 2015. A total of 155 species belonging to 48 families (resident and migratory) under 17 orders were recorded, of which 13 come under various IUCN Red List categories: one ‘Endangered’—Egyptian Vulture Neophron percnopterus; five ‘Vulnerable’—Common Pochard Aythya ferina, Greater-Spotted Eagle Aquila clanga, Sarus Crane Grus antigone, Lesser White-Fronted Goose Anser erythropus, and Woolly-necked Stork Ciconia episcopus; and seven ‘Near Threatened’—Ferruginous Duck Aythya nyroca, River Lapwing Vanellus duvaucelii, Indian River Tern Sterna aurantia, Painted Stork Mycteria leucocephala, Oriental Darter Anhinga melanogaster, Blossom-headed Parakeet Psittacula roseata, and Alexandrine Parakeet Psittacula eupatria. The Shannon-Weaver index of diversity was highest during winter (H’= 1.9) followed by autumn (H’= 1.9) then spring (H’= 1.5), and was lowest during summer (H’= 1.4). Though this wetland is highly productive and provides homes to many threatened species, untreated industrial effluents from adjoining areas sometimes create problems. The discharge of pollutants should be stopped through strict enforcement of environmental laws and policies.

Population decline is a process, yet estimates of current extinction rates often consider just the final step of that process by counting numbers of species lost in historical times. This neglects the increased extinction risk that affects a large proportion of species, and consequently underestimates the effective extinction rate. Here, we model observed trajectories through IUCN Red List extinction risk categories for all bird species globally over 28 years, and estimate an overall effective extinction rate of 2.17 × 10 −4 /species/year. This is six times higher than the rate of outright extinction since 1500, as a consequence of the large number of species whose status is deteriorating. We very conservatively estimate that global conservation efforts have reduced the effective extinction rate by 40%, but mostly through preventing critically endangered species from going extinct rather than by preventing species at low risk from moving into higher-risk categories. Our findings suggest that extinction risk in birds is accumulating much more than previously appreciated, but would be even greater without conservation efforts.

Comprehensive Survey

SummaryAlthough birds are among the best studied taxa, many of the globally threatened species lack the information required to fully assess their conservation status and needs. One such species is the Anjouan Scops Owl Otus capnodes which was presumed extinct until its rediscovery to science in 1992. Based on the limited extent and decline of the moist forests in the highlands of Anjouan in the Comoro Islands, a population size of only 100–200 pairs was estimated and the species was classified as ‘Critically Endangered’. The current study is the first comprehensive survey ever conducted on this species, and aimed to establish the current distribution and population size. Point counts with distance sampling were conducted across the agroforestry and forest zones of Anjouan in both a dry and wet season. A niche suitability model predicted the species distribution to be wider than expected with owls observed as low as 300 m altitude and in highly modified agroforestry habitats. However, the encounter rate in natural relatively undisturbed forest was significantly greater than in other habitats. The wider than expected geographic range of O. capnodes supports a possible downlisting of this species on the IUCN Red List to ‘Endangered’. Population size was found to be far greater than previously thought, at approximately 3,450 individual owls in the dry season and 5,450 in the wet season. These results show the importance of investing in robust surveys of poorly known and cryptic bird species, and provide up to date and important information for landscape scale conservation planning in the Comoros Islands.

Abstract. Isworo S, Oetari PS. 2020. Mangrove vegetation and bird communities around Tegal Port, Central Java, Indonesia. Biodiversitas 21: 1551-1560. The ecological balance in Tegal harbor area needs to get serious attention due to the impacts of Tegal Port activities. For this purpose, the diversity of mangrove and avifauna (bird) can be used as bio-indicators of the ecological stability of the area. This study aimed to assess and analyze the diversity of plants and avifauna (birds) that live in mangrove and coastal zones around Tegal Port development area. Data collection was conducted using purposive random sampling method on two sites for vegetation and three sites for avifauna. The importance value index, Shannon-Wiener diversity index and Sorensen’s similarity index was calculated for the vegetation. For birds, we calculated the diversity and similarity index as well as identified their conservation status based on the IUCN Red List, CITES and government regulations. In terms of vegetation, Rhizophora mucronata and Avicennia marina dominate Site 2 (Tegalsari) while Casuarina equisetifolia and R. mucronata dominate Site 3 (Alam Indah Beach). Overall, the vegetation has low biodiversity index and similarity between sites is also low. For bird, there are 37 species from 18 families. Site 1 (Muara Reja) has the highest number of species with 29 species, followed by Site 2 (Tegalsari) with 25 species, and Site 3 (Alam Indah Beach) with 22 species. The three sites have moderate diversity index and there is high similarity index between sites. All bird species found in the study sites are listed as Least Concern under IUCN Red List, while there are two species protected under national protection law, i.e. Ardea alba and Glareola maldivarum. In general, the condition of mangrove vegetation around Tegal Port has low diversity. This suggests that the pressure on the environment is quite high, causing only few plant species to be able to live and dominate the ecosystem. The limited vegetation also causes birds community, especially the protected A. alba and G. maldivarum in Site 2, becomes increasingly difficult to find, because places to find food, breeding places and places to rest are disturbed.

SummaryThirty-two percent of bird species in South-East Asia are likely to become extinct by the end of this century. However, due to a lack of data this number may be an underestimate. The Chestnut-headed Partridge Arborophila cambodiana found in south-west Cambodia’s Cardamom Mountain range is a largely unknown potentially at-risk species. We used line transects and camera traps to survey A. cambodiana in four protected areas in the Cardamom Mountains to estimate population densities. We also assessed their current distribution range and broad scale habitat changes from 1996 to 2016. We found A. cambodiana in evergreen and semi-evergreen forest at a density of 1.23 calling males/km2, and at altitudes above 400 m and where the slope was between 11 and 43o. From 1996 to 2016 A. cambodiana’s potential habitat decreased by 11%, whilst the total evergreen forest cover in the Cardamom Mountains decreased by 20%. A. cambodiana has a very restricted range within which the habitat has been fragmented. Compounded by human disturbance and development activities that negatively affect the species, we suggest a revision of its IUCN Red List status from ‘Least Concern’ to ‘Near Threatened’ as it partially meets a range of threatened Red List species criteria.

Baseline Information

Birds are ecological indicators of ecosystem health. Baseline information on bird diversity are, therefore, important for ecological monitoring. Such information is, however, sorely lacking for many areas outside the protected areas. Here, we explore the avian diversity and present a comprehensive checklist for the non-protected regions of Trashiyangtse District in northeastern Bhutan. We also categorise the bird species by their residency pattern, feeding guilds, abundance, and IUCN Red List status. We conducted an avifauna exploration for a period of four years from 2017 to 2020, mostly through opportunistic encounters coinciding with regular field visits. We recorded a total of 273 bird species belonging to 173 genera, 69 families and 19 orders. Passeriformes was the most dominant order with 41 families and 174 species and Muscicapidae was the most dominant family with 12 genera and 32 species. Most birds were altitudinal migrants (39%), insectivorous (45%), and occasional (44%) in terms of residency pattern, feeding guild, and abundance, respectively. Only one species (Ardea insignis) was listed as Critically Endangered and one (Haliaeetus leucoryphus) as Endangered. Our study identified the non-protected regions of Trashiyangtse District as an important bird diversity area in Bhutan.

Located in the Trans-Gangetic Plains of India, Kurukshetra is dotted with a number of man-made, perennial, sacred ponds of great historical and religious importance.  These wetlands also serve as important wintering and stopover sites for birds coming from the Palearctic region.  Surveys were conducted from April 2014 to March 2015 to recordthe diversity and status of avifauna in four sacred ponds of Kurukshetra. Point counts and direct observations were used to record the bird species.  A total of 126 bird species of 98 genera belonging to 45 families and 16 orders were identified, of which 41 were winter migrants, six were summer migrants, and 79 were residents.  Anatidae (n=15) was the most common family, followed by Ardeidae (n=8), and Motacillidae and Muscicapidae (n=7 each).  Based on the guilds, 37 species were carnivorous, 36 omnivorous, 29 insectivorous, six herbivorous, six frugivorous, five granivorous, four insectivorous/nectarivorous, and three piscivorous.  Of the species recorded, five species are classified as Near Threatened and one species as Vulnerable in the IUCN Red List of Threatened Species; nine species are listed in Appendix II of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and six species are included in Schedule I of the Indian Wildlife (Protection) Act, 1972.  We hope that this study will provide a baseline for future research on monitoring the population and seasonal changes in the bird assemblageof sacred ponds.
