Biodiversity and habitat use of wintering and breeding waterbirds in Burullus Lake (Ramsar site), Egypt

The present study seeks to assess the bird biodiversity at the Important Bird Area (IBA) and Ramsar site,Lake Burullus, northern Egypt. Waterbirds biodiversity was assessed at 14 selected sites in the lake duringwinter and spring seasons. The assessment included richness, composition, evenness, abundance, andSimpson and Shannon-Wiener diversity indices. Bird species diversity varied spatially and temporallyamong different sites during the study period. Estimated species richness was 49 species. Winter birdswere mainly migratory waterbirds like waterfowl, distributed in the islets for foraging, which was the mainactivity of 51% of total birds, followed by 36% roosting and 13% breeding at the lake. Evidence ofbreeding was recorded, such as collecting nest material, courtship behavior and food collecting forjuveniles. The hierarchical cluster analysis separated the lake sites into four distinctive habitats: lakeshores, open water, islets and reed beds. Seven bird species showed significant affinities with differenthabitat types: Laughing dove (Streptopelia senegalensis) favored the lake shores habitat (P< 0.04); Littlebittern (Ixobrychus minutus) (P< 0.04), Pied kingfisher (Ceryle rudis) (P< 0.04), Common kingfisher(Alcedo atthis) (P< 0.02), Pied wagtail (Motacilla alba) (P< 0.04), and Graceful prinina (Prinia gracilis)(P< 0.01) were found in islands habitat. Little egret (Egretta garzetta) dominated the reed beds habitatgroup (P< 0.03). The results reflected the importance of Burullus Lake as a wintering and breeding habitatfor birds and suggested that more implemented conservation and management strategies should beadopted.

Pilot biodiversity assessment of the Hkakabo Razi passerine avifauna in northern Myanmar – implications for conservation from molecular genetics

SummaryThe Hkakabo Razi region located in northern Myanmar is an Important Bird Area and part of the Eastern Himalayan Biodiversity Hotspot. Within the framework of the World Heritage Convention to enlist the site under criterion (ix) and (x), we conducted a biodiversity assessment for passerine birds using DNA barcoding and other molecular markers. Of the 441 bird species recorded, we chose 16 target species for a comparative phylogeographic study. Genetic analysis was performed for a larger number of species and helped identifying misidentified species. We found phylogeographic structure in all but one of the 16 study species. In 13 species, populations from northern Myanmar were genetically distinctive and local mitochondrial lineages differed from those found in adjacent regions by 3.9–9.9% uncorrected genetic distances (cytochrome-b). Since the genetic distinctiveness of study populations will be corroborated by further differences in morphology and song as in other South-East Asian passerines, many of them will be candidates for taxonomic splits, or in case an older taxon name is not available, for the scientific description of new taxa. Considering the short time frame of our study we predict that a great part of undetected faunal diversity in the Hkakabo Razi region will be discovered.

Birds of Parque Estadual do Tainhas, an important protected area of the highland grasslands of Rio Grande do Sul, Brazil

Parque Estadual do Tainhas – PET (Tainhas State Park) is a protected area with significant extensions of natural grasslands located in highland grasslands of northeastern Rio Grande do Sul state, Brazil, and recognized as an Important Bird Area. Our aim was to record the bird species richness of PET with a greater sampling effort than previous studies at the site, including unpublished data such as occurrence status of most species and evidence of breeding of some of them in the park. We surveyed birds between 2012 and 2018 performing aleatory trails covering mainly the central portion of PET (1,500 ha). We also added records from published studies. We listed 208 species, of which 203 were recorded during our fieldwork (including 18 species of conservation concern). The estimated richness was 222.22 (SD = 10.91) species, according to Jackknife 1 method. This result represents a 58% increase in the species richness of the park and shows that long-term monitoring of the bird community allows to access more accurate richness and to identify the regular species (core avifauna) of the park. The presence of 55 breeders and threatened species shows the importance of this protected area for breeding and conservation of grassland birds, such as Urubitinga coronata, Cinclodes pabsti, Xolmis dominicanus, Anthus nattereri, Xanthopsar flavus, and Sporophila melanogaster.

Predicting hydrological impacts of the Yangtze-to-Huaihe Water Diversion Project on habitat availability for wintering waterbirds at Caizi Lake

Quantifying the relationship between hydrological regime and habitat availability is the first step to predict potential impacts of water engineering projects on waterbirds, particularly in periodically flooded wetlands. The proposed Yangtze-to-Huaihe Water Diversion Project (YHWD) cuts through Caizi Lake, which is of international importance for wintering waterbirds. In order to explore the potential impacts of the project on habitat availability for the wintering waterbirds, we first built linear models to fit relationships between land cover patterns and water level dynamics in the lake, and then used generalized linear mixed models to test effects of habitat variables (water area, grassland area and mudflat area) on bird abundances of different functional groups. The avian habitat use differed among guilds, and was correlated with the land cover pattern, which was strongly dependent on seasonal water level fluctuations. Following water recession in autumn, the exposure of riparian habitats was more prominent in the eastern part of the lake, where the channel of the proposed YHWD project is located. This part of the lake is also where we located most of the important bird areas. Compared to the current situation, 54.3% of the grassland and 60.5% of the mudflats are predicted to be lost during winter due to the projected water level rise, resulting in reduced habitat availability for grass foragers, invertebrate eaters and tuber feeders. In order to mitigate potential impacts of the YHWD project, we suggest habitat compensations by construction of artificial habitats, and maintenance of water level regime at the whole lake by restoring similarity in water level fluctuations between Xizi Lake and Caizi Lake.

Bird diversity in the coastal talukas of Sindhudurg District, Maharashtra, India

The list of birds of Sindhudurg coastal district was compiled based on primary and secondary information. All observations were made along the Sindhudurg coast, i.e., from Terekhol to Vijaydurg. Wetland birds were recorded during sampling while terrestrial birds were recorded opportunistically. Besides, we also collated bird occurrence records from published literature (including grey literature and online resources) to prepare a comprehensive list of birds for Sindhudurg coast. During our study, we recorded 283 species, and 24 more species were compiled from secondary sources. Altogether, 307 species belonging to 78 families and 22 orders were recorded from the Sindhudurg coast. Order Passeriformes was dominant with 111 species. Among the 307 species, four species are endemic to the Western Ghats. Three species of vultures had been reported earlier but two were not encountered in recent years. Great Knot (EN), Woolly-necked Stork (VU) and 14 other species (NT) fall under various threat categories of IUCN. Species richness was higher in Vengurla (256) followed by Malvan (247) and Devgad talukas. Construction of homestays, unregulated tourism in coastal areas, and conversion of natural habitats to meet increasing tourism are the major threats to the coastal avifauna of the district. A high species richness of birds in Sindhudurg coast is attributed to the availability of a wide array of habitats (coastal to woodlands with different degrees of anthropogenic disturbances). Considering the high species richness of birds and livelihood dependency of humans on the coastal zones, a few estuaries namely Mochemad, Karli and Mitbav estuaries may be recognized as community/ conservation reserve to manage the ecosystem sustainably for long-term conservation of these estuaries and sub-habitats therein. Also, those sites can be perceived as Important Bird and Biodiversity Areas of IBCN as they fulfill the IBA criteria.

Selecting a suite of potential partner sites for the Adelaide International Bird Sanctuary to aid shorebird conservation in the East Asian–Australasian Flyway

Migratory shorebird species depend on a suite of interconnected sites and protection of these sites as part of a network is an increasingly used conservation approach. Partnering sites based on shared migratory bird species can be a powerful tool for implementing conservation action. To assist the Adelaide International Bird Sanctuary (AIBS), South Australia, in expanding their conservation impact across the East Asian-Australasian Flyway, we generated a list of 81 sites to consider for potential partnerships. We developed the list using existing shorebird count data for seven high priority migratory shorebirds that spend the austral summer at AIBS, such as Bar-tailed Godwit (Limosa lapponica) and Great Knot (Calidris tenuirostris). We computed a scaled abundance across all species to develop a categorical indicator of importance of each potential site for its shared species richness and abundance. Based on assessments of literature, existing conservation plans, and interviews with experts, we also evaluated each potential site’s feasibility for ecotourism, conservation management, and existing or potential partnerships. This process resulted in a list of 20 sites for the AIBS to consider for possible partnerships in nine countries that met some combination of values for shared shorebird species, inclusion in one or more current site designation schemes, existing or potential opportunities for tourism, habitat management, or partnerships. Additional sites that either have high or medium abundances of shared shorebird species or that have been designated as important by other criteria (Ramsar, Important Bird and Biodiversity Area) were identified. We recommend this methodology be applied to other sites seeking to form cross-boundary partnerships to help further the conservation of highly mobile species.

Urgent conservation needs in the Sikkim Himalaya biodiversity hotspot

ABSTRACTSikkim is the second smallest state in India. It has a human population of approximately 619,000 and covers a mountain-locked area of 7,096 km2. Recognised as a biodiversity ‘Hot Spot’ of global significance, it is situated within the Eastern Himalaya Biodiversity Hotspot and is rich in affluent flora and fauna diversity. Eighty-three per cent of Sikkim’s land area is covered with forest distributed in five ecoregions: 1) Tropical, 2) Sub-Tropical, 3) Temperate, 4) Alpine Forest and Scrub, 5) and Trans-Himalayan ecoregions. Sikkim encompasses 8 protected areas covering 47% of the State’s total geographical area and 11 Important Bird Areas (IBA), declared by Birdlife International. It also has undocumented mountain peaks, glaciers, rivers/streams, high-altitude lakes and geothermal springs which are yet to be explored. Sikkim, with its high biodiversity, is situated in a fragile ecosystem of tropical mountains in the Eastern Himalaya. It is currently under threat of irreparable damage as a result of several factors, including the melting of glaciers due to global warming, floods, landslides, invasive hydrothermal projects, road construction, deforestation and the destruction of trees for fuel and domestic purposes, growth in tourism – and much more. All these issues must be properly addressed in order to protect and conserve the unique biodiversity of the Sikkim Himalaya.

Avifauna study of Tanjung Piai, Johor, Malaysia

Tanjung Piai is located in the southern-most tip of mainland Asia. It is one of the most important Ramsar site and Important Bird Area (IBA) in Malaysia. However, this site is receiving a major threat from shipping traffic in Malacca Straits which led to several impacts such as coastal erosion and pollution. Avifauna study of Tanjung Piai was conducted from May until August 2017. The objective of the study is to document the diversity of birds in the wetland areas of Tanjung Piai. The bird was recorded by using direct observation technique as well as mist-net trapping method. A total of 228 individuals, 32 species, and 23 families were recorded. The Shannon-Weiner Index, H’, is 3.33 indicated that Tanjung Piai has high diversity and serve as a good habitat for bird species.

Spatio-Temporal Patterns of Waterbird Assemblages in Cuba’s South Coast Wetlands: Conservation Implications

Cuba is the largest Caribbean island, supporting the most extensive wetlands in the region. Of the ~370 bird species in this country, approximately 40% are wetland-dependent and most are migratory. Knowledge of bird use of Cuba’s wetlands is critical for regional conservation. This study characterized waterbird assemblages in Cuban south coastal wetlands, reports spatio-temporal variations in waterbird diversity and suggests conservation strategies. We conducted 543 surveys across six wetlands (2011–2013). We recorded 110 species. Blue-winged Teal (Spatula discors) and Least Sandpiper (Calidris minutilla) were the dominant species. The site with the highest richness and waterbird abundance was Humedal Sur de Los Palacios. Differences in waterbird composition were identified among sites and seasons but not among years. No differences were found in spatial or temporal variability in abundance among sites, seasons or years. Assemblage composition was not spatially dependent on the location of wetlands. Twelve species were at abundance levels exceeding 1% of their estimated global population. This study highlights the global importance of the Cuban south coast to waterbird conservation, particularly during fall migration and the uniqueness of Humedal Sur de Los Palacios. We encourage creation of new Ramsar sites, an Important Bird Area and a new protected area.

Species Composition, Relative Abundance and Habitat Association of Birds in Arbegona, Garemba Forest, Southern Ethiopia

The present study was carried out in Arbegona Garemba forest from August June 2017 to February 2018 during wet and dry seasons. The study area was stratified based on vegetation composition. Accordingly, Modified habitat, Alpine bamboo forest, and Sub-Afro alpine /Ericaceous belt/ were considered. A line transects count aided by binocular was employed to investigate avian species diversity, relative abundance and Habitat association. Thus10 transect lines of 0.75km lengths with a width of 0.15km or less wereused to cover 30% of the area. A total of 74 bird species consisting of 5 near endemics, 2 globally threatened and 3 Palearctic migrants were recorded.Average vegetation height was a good predictor for total bird abundance and bird species richness during dry season. Altitude accounted more in total species richness and bird species abundance during wet season. Though, slope was a good predictor for bird species abundance during dry season. It can be concluded that the patch of forest and its surrounding is an important bird area for migratory, endemic, and global threatened species. Therefore, it should be conservation priority area; hence, the study suggests that conservation together with ecotourism development is needed for its sustainability.

Spatial distribution and nesting behavior of the Black winged-stilt (&lt;i&gt;Himantopus himantopus himantopus&lt;/i&gt;, Linnaeus 1758) in the urban wetland of Dakar Technopole (Senegal, West Africa)

Wetlands are important areas in the conservation of biodiversity and play a key role in the ecosystems regulation. Thus, considering that climate change effects combined with anthropogenic pressures on natural resources are causing loss of biodiversity in Sahelian countries such as Senegal, we need to do regular stock assessments. For this, we aimed at studying the Black winged-stilt (Himantopus himantopus himantopus) in the urban wetland of Technopôle in the Niayes of Dakar (capital of the republic of Senegal). Our study is focused on the spatial distribution and nesting of the Black winged-stilt (Himantopus himantopus himantopus) in Technopole, which is classified in the list of Important Bird Areas (IBAs) by Birlife International since 2001 under A4i criteria and is an important biodiversity hotspot. The Niayes of Dakar constitute a particular ecosystem of wetland, they play a determining role in the reproduction and the survival of manies birds’ species. The nesting study was conducted from May to August 2012 and from May to August 2017. The maximum numbers of Black winged-stilt count during these periods are 531 individuals for 2012 and 766 individuals for 2017. However we highlight a decrease of the number of Black winged-stilt in the Technopole after the onset of the rains. Breeding data (25 nests in 2012 and 79 in 2017) show that this urban wetland is a preferred nesting site for Black winged-stilt. We report for the first time in this paper, so many Black wingedstilt nests in Senegal. Despite the disturbances related to anthropogenic factors, the breeding success of the Black winged-stilt reached 89.6% in May 2017. Thus, we believe that a strengthening of a conservation action plan of this site is urgent for a better preservation of the biodiversity, particularly the avian resources.

Assessing global popularity and threats to Important Bird and Biodiversity Areas using social media data

Understanding worldwide patterns of human use of sites of international significance for biodiversity conservation is crucial for meeting global conservation targets. However, robust global datasets are scarce. In this study, we used social media data, mined from Flickr and Twitter, geolocated in Important Bird and Biodiversity Areas (IBAs) to assess i) patterns of popularity; ii) relationships of this popularity with geographical and biological variables; and iii) identify sites under high pressure from visitors. IBAs located in Europe and Asia, and in temperate biomes, had the highest density of users. Sites of importance for congregatory species, which were also more accessible, more densely populated and provided more tourism facilities, received higher visitation than did sites richer in bird species. We found 17% of all IBAs assessed to be under very high threat also received high visitation. Our results show in which IBAs enhanced monitoring should be implemented to reduce potential visitation risks to sites of conservation concern for birds, and to harness the potential benefits of tourism for conservation.

Enhancing bird diversity through improved water management in a Viet Nam wetland national park

U Minh Thuong National Park, one of the two largest remaining peat swamp, melaleuca forests in Viet Nam is a very Important Bird and Conservation Area because of its diverse wetland habitats. A devastating forest fire in 2002 resulted in a new regime of fire control based on an imposed permanent flooding regime over large areas of the Park that led to severe wetland and forest degradation. This in turn negatively impacted on bird species diversity and populations. In 2009, the Government of Viet Nam and the park authority adopted an improved water management practice. A survey four years later recorded two new species in the list of 159 bird species for the park. Of these, 25 threatened species were using the wetland park and adjacent Buffer Zone for living and feeding habitat. Based on the largest count occurring during three continuous days, the water bird population in the bird colony in 2013 increased by 33 per cent compared to the 2009 level. The positive response of avifauna to the changes in U Minh Thuong with respect to the hydrology of seasonally flooded melaleuca wetland forest indicates the need to understand how the ‘normal’ wetland processes operate in support of biodiversity conservation before modifying them for fire management.

Range contraction and conservation of the endangered Yellow Cardinal

The Yellow Cardinal (Gubernatrix cristata) is distributed in Argentina, Uruguay and Brazil, inhabiting environments of xerophytic woodland and savannah; it is considered globally Endangered since 1994. Populations are under pressure from loss and modification of habitat and from capturing for the cage bird trade. We compared in a geographical analysis the past (1826–1994) and recent (1995–2018) distributional ranges of the Yellow Cardinal and its affinities to ecoregions, land use cover and presence in protected areas, and assessed continuity vs. fragmentation of the current distribution using the method of Medium Propinquity. We used 1191 location records from reviewed sources and our field observations. We found a reduction of the original distribution to areas where native savannahs are still in good condition. In Argentina, the species has disappeared from 8 out of 16 provinces. The altitudinal range of the species extends up to 1100 m, rather than 700 m as reported in earlier reviews. It is clearly associated with savannah, shrubland, and grassland land cover categories. In regions where it disappeared, suitable habitat remained at 33% of points where it was formerly present, with capturing for the cage bird trade as a likely cause of disappearance. Medium propinquity analysis showed as yet little fragmentation in the current distribution, except for a separation between northern and southern populations. The Yellow Cardinal is distributed mainly outside protected areas; it is found in 31 Important Bird Areas, 22 of which are not protected and are under threat from habitat loss through the expansion of agriculture. We urge improved control of illegal capturing and the maintaining of native vegetation in population strongholds of the Yellow Cardinal.

Bird conservation in Africa: the contributions of the Ibadan Bird Club

The Ibadan Bird Club has met 19 times at monthly intervals between February 2016 and August 2017, and 264 people (155 male and 109 female) have registered as members. During this period, the club has successfully built local capacity in bird conservation, and 111 bird species, distributed in 39 families, have been documented in an urban Important Bird Area, southwestern Nigeria. The findings of this citizen science initiative are essential for conservation purposes.

An assessment of climate change vulnerability for Important Bird Areas in the Bering Sea and Aleutian Arc.

Recently available downscaled ocean climate models for the Bering Sea and Aleutian Arc offer the opportunity to assess climate vulnerability for upper trophic level consumers such as marine birds. We analyzed seasonal and annual spatial projections from three climate models for two physical climate variables (seawater temperature and sea ice) and three forage variables (large copepods, euphausiids, and benthic infauna), comparing projected conditions from a recent time period (2003–2012) to a future time period (2030–2039). We focused the analyses on core areas within globally significant Important Bird Areas, and developed indices of the magnitude of projected change and vulnerability agreement among models. All three climate models indicated a high degree of change for seawater temperature warming (highest in the central and eastern Aleutian Islands) and ice loss (most significant in the eastern Bering Sea) across scales, and we found those changes to be significant for every species and virtually every core area assessed. There was low model agreement for the forage variables; while the majority of core areas were identified as climate vulnerable by one or more models (72% for large copepods, 73% for euphausiids, and 94% for benthic infauna), very few were agreed upon by all three models (only 6% of euphausiid-forager core areas). Based on the magnitude-agreement score, euphausiid biomass decline affected core areas for fulmars, gulls, and auklets, especially along the outer shelf and Aleutian Islands. Benthic biomass decline affected eiders along the inner shelf, and large copepod decline was significant for storm-petrels and auklets in the western Aleutians. Overall, 12% of core areas indicated climate vulnerability for all variables assessed. Modeling and interpreting biological parameters to project future dynamics remains complex; the strong signal for projected physical changes raised concerns about lagged responses such as distribution shifts, breeding failures, mortality events, and population declines.

Important areas and conservation sites for a community of globally threatened marine predators of the Southern Indian Ocean

In the Southern Ocean, the impact of environmental changes and increasing human encroachment is causing declines in several populations of seabirds. Amsterdam island (77°33′E; 37°50′S) hosts some emblematic but globally threatened seabird species with alarming population trends. In 2017, concerns about Amsterdam Island's marine biodiversity led to the extension of a marine reserve to the boundaries of the exclusive economic zone (EEZ). Nevertheless, it is unknown whether this protected area is sufficiently large to encompass the most important foraging hotspots of the threatened seabirds, particularly during key stages of their life cycle (e.g. breeding period). We analysed movements of four threatened seabird species using a tracking dataset acquired over several breeding seasons from Amsterdam Island: Amsterdam albatross Diomedea amsterdamensis, sooty albatross Phoebetria fusca, Indian yellow-nosed albatross Thalassarche carteri and northern rockhopper penguin Eudyptes moseleyi. Our objectives were threefold: (1) characterise the at-sea distribution of the above-mentioned populations and delineate the marine Important Bird and Biodiversity Areas (mIBAs) triggered by them; (2) assess the potential threat at-sea by quantifying the overlap between seabird distribution and longline fishing efforts; (3) evaluate the coverage of identified mIBAs by marine protected areas and suggest complementary conservation actions. The identified important areas fell within the boundaries of the EEZ, but vastly exceeded the former reserve. Thus, our results reinforce the justification of the recent expansion of the reserve to the boundaries of the EEZ. However, overall seabird distributions extended beyond the EEZ (5 to 50% of the locations) and we found substantial overlap with longline fishing in the high seas. Our results provide a spatio-temporal envelope of where and when bycatch mitigation and observer coverage of longline fisheries should be mandated and enforced.

A Preliminary Survey of Birds in Pench Tiger Reserve, Madhya Pradesh, India

A preliminary survey of bird species and habitat in the Karmajhiri Range, Pench Tiger Reserve was conducted during March 2014 - May 2014. The aim of this study was assessment of avian population by addressing some ecological status such as faunal type, phenological traits, trophic status, occurence and protection status of birds species. 221 species of birds were recorded from study area. Out of 26 order in India 16 order of birds were presented in and around Pench Tiger Reserve (PTR) which comprises 61 families. PTR provides habitat for three critically endangered species, namely White-rumped Vulture (Gyps bengalensis Gmelin, 1788), Red-headed Vulture (Sarcogyps calvus Scopoli, 1786) and Indian Vulture (Gyps indicus Scopoli, 1786). Regarding species protected by Berne convention 34 species are listed in Appendix 2 (strickly protected fauna) and only one are represented in Appendix 3 (Protected fauna) House Sparrow (Passer domesticus Linnaeus, 1758). Based on the AEWA (African-Europian Migratory Waterbird Agreement) bird list, 18 bird species are noted in the study area. The dominance of Oriental faunal type provide information on the relationship of the surveyed avifauna to the biogeographical zones. We were recorded 28 biome restricted bird species. This assessment also supports and justifies its classification as an Important Bird Area “IBA” because of the importance and abundance of avian species. Its provide shelter and hosts to birds. To conserve birds species in tropical deciduous forest in PTR, it will be necessary to preserve large areas of contiguous forest and monitor the effect of Habitat fragmentation and other development activities in and around forest area will have impact on their foraging, breeding and subsequently their population. These scientific findings will help to evaluate the effectiveness of legislation and policies for bird protection and will under in future conservation action for birds and their habitats.
