Protected and Unprotected Areas as Refuges for Bird Conservation in Southeastern Coahuila, Mexico

Information gaps about the distribution of species hamper the evaluation of conservation status and decisions on biodiversity conservation, affecting areas with high species richness and endemism to a greater extent. In this context, carrying out biological inventories in protected and unprotected areas is an important tool to fill these gaps by providing data on the composition, richness, and abundance of species in each locality. The southeastern region of Coahuila (northeast Mexico) is a region where biodiversity research is required, as anthropogenic activities pose a serious threat to the avian diversity of this region. The present study aimed to compare the capacity of protected and unprotected areas to support the richness, abundance, and composition of bird species, as well as providing a list of bird species from eight areas located in this region. The point count method was conducted at the sites, and one-way ANOVA was used to determine the effect of area type on species richness and abundance. Based on our field observations, literature review, and digital databases, the avifauna of these eight areas includes 388 species in 63 families. Of these, 5 species are endemic to Mexico, 6 species are of global conservation concern, and 35 species are of regional conservation concern. The species richness found in this study supports the importance of protected and unprotected areas in southeastern Coahuila. The results of our study highlight the need for further assessment to conserve the avian community, especially considering the increasing threats of anthropogenic disturbance, as well as additional studies that will allow for better characterization of the avifauna of the region. This will help to ensure the conservation of the birds currently threatened by strong anthropic pressure due to the conversion of semiarid ecosystems to agricultural and livestock areas as well as increasing urbanization.

Richard Maack's Vilyui expedition in the study of avifauna and gallinaceous birds (Gallinaceae) of Eastern Siberia

The article is dedicated to the 170th anniversary of the Vilyuisk (Yakutia) expedition organised by the Siberian (Irkutsk) branch of the Imperial Russian Geographical Society (1853-1885). It was led by Richard Karlovich Maack (Germ. Richard Otto Maack), a Russian naturalist of German origin and explorer of Siberia and the Far East. It also contains some information on the Pribaikalia and Transbaikalia, taken along the way during the subsequent Amur (1855-1856) and Ussuri (1859-1960) expeditions. The route, dates, and composition of the expedition are described and the contribution of the scientist to various fields of natural science and, above all, to the study of vertebrates of the region is evaluated. Scientists have identified the habitat of amphibians and reptiles (4 species), birds (121), mammals (34), which is relatively large against the background of regional studies conducted in Eastern Siberia at that time. According to the lists of bird species published in the fundamental work of the scientist "Vilyuisky district of the Yakut region" [1883-1887], the distribution of 5 species of Gallinaceous birds (Gallinaceae) in the middle of the XIX century was revealed – Hazel Grouse, Western and Black-billied Capercaillies, Black Grouse, Willow Ptarmigan. For Transbaikalia and Pribaikalia, the habitat of two more species is noted - Gray and Bearded Partridges. The Common Pheasant was accounted for by R. K. Maack only in the Amur region and the Amur region (Far East). In general, over the century and a half of the history of studying Gallinaceous birds, their species composition has practically not changed in the researcher's work area. In Yakutia, it was replenished with species from the eastern and southern regions, living there Rock Partridge and Siberian Grouse. On the scale of Eastern Siberia, only the Pheasant is currently supplementing the Gallinaceous birds list as a new species in the region, documented in the south of Eastern Siberia – in the Eastern Sayan bordering the Baikal region and in some places of Transbaikalia (not yet precisely confirmed).

Observations of avifauna on Rēkohu / Wharekauri / Chatham Island, Chatham Islands group, in February 2023

Rēkohu / Wharekauri / Chatham Island (hereafter Rēkohu) is the largest island in the Chatham Islands group, 800 km east of the Te Wai Pounamu / South Island, Aotearoa / New Zealand. This island has an avifauna of 170 taxa. Here, we present a list of bird species encountered during an eight-day undergraduate field trip in February 2023. Based on visual encounters or via calls heard, we encountered 38 species of bird (two seabirds, eight coastal birds, six freshwater birds and 22 terrestrial birds) across 13 locations over six days. The most common species sighted were common starlings (Sturnus vulgaris vulgaris), followed by white-fronted terns (Sterna striata) and black swans (Cygnus atratus). We encountered a Chatham Island tūī (Prosthemadera novaeseelandiae chathamensis) in Nikau Bush Reserve, c.35 km north of the translocated population in Awatotara Valley. We also present the first list of bird species for Motuhinahina and a nearby limestone rock stack in Te Whanga Lagoon. Birds encountered there included Chatham Island shag (Leucocarbo onslowi), Pitt Island shag (Phalacrocorax featherstoni), Buff weka (Gallirallus australis hectori) and New Zealand little penguin (Eudyptula minor minor). We formally report the presence of feral emu (Dromaius novaehollandiae), including chicks, at Te Matarae, where there is self-sustaining population following their release to the wild years ago. In previous observations, feral chicken (Gallus gallus gallus) and turkey (Meleagris gallopavo) were ‘semi-wild’ on the basis that observations made of these species were well outside sites of human habitation. In the case of turkey, they are in the process of self-establishing. We suggest a full census is required to determine the status of these populations, particularly emu. As the emu population is self-sustaining, they should be considered as a new addition not only to the avifauna of the Chatham Islands group but to Aotearoa / New Zealand.

Рotential threats of Kakhovka catastrophe to bird populations of different ecological groups

Any military action involves a number of risks for the existence of animals. In the event of the destruction of hydraulic structures, not only aquatic ecosystems usually suffer, but also the ecosystems of islands and banks. Undermining the dam of the Kakhovska hydroelectric power station had a wide range of negative impact on the life of animals. A number of its consequences manifested themselves immediately after the destruction of the dam connected with drainage of bottom sediments in some regions and flooding of the coast in others. But one should also expect the transformation of faunal complexes associated with long-term changes in the water regime, and in some regions with drying and moisture deficiency. The purpose of this work is to assess the species composition of birds whose populations will suffer population losses as a result of the Kakhovka catastrophe in the short and long term on a regional and global scale. The published lists of bird species for the territories affected by the Kakhovka catastrophe an analysis was made: for the Kakhovka reservoir, the 'Kinburn Kosa Regional Landscape Park, the Black Sea Biosphere Reserve; and for the registration of some rare species in the region. Questionable data was checked against an electronic database https://uabirds.org/. We assessed the species composition of birds whose populations may decrease in number as a result of the Kakhovka catastrophe in the near and long term. Problems of regional and global scale are considered. The status of residence and ecology of birds were taken into account. Birds affected as a result of the Kakhovka catastrophe were divided into 3 groups: І — 82 species — birds nesting in the region of the disaster and lost part of their populations this year. These are birds that build nests in aquatic vegetation, not high in trees, shrubs, on the ground on the islands; ІІ — 69 species — birds that will lose their habitats in the coming nesting seasons due to changes in the Dnieper channel, water regime and the development of devastation processes. These are limnophilous that inhabited the thickets of the coastline and the islands of the Dnieper; ІІІ — 121 species — birds that will lose habitats for feeding and shelter during migration and wintering. The number of not only populations that nest in Ukraine will suffer, but also those migrating from Europe and Asia. And a group of birds (33 species) that are unlikely to be affected. The catastrophe of the undermining of the dam of the Kakhovska hydroelectric power station harms the biodiversity and integrity of habitats on a large area of the banks of the lower reaches of the Dnieper. The effects of the disaster on natural communities will have a lasting impact. We predict a change in the biotopes of the existence of birds in the direction of degradation of wetlands and drainage of terrestrial ones, which will lead to a change in the species composition of birds in the region. Relevant in the future will be the study of the succession processes of ecosystems on the banks of the lower reaches of the Dnieper and changes in the communities of birds that inhabit them. The consequences of the catastrophe we have an impact on migratory bird species on a global scale.

Most recent composition of the ornithofauna of the Middle Irtysh region, Russia

Aim. The work was to compile a list of bird species and their status in the forest-steppe and steppe of the Middle Irtysh region at the present time and to analyse their potential ability in terms of the transmission of influenza viruses that pose a danger to humans and farm animals.Materials and Methods. The study of avifauna and their status in the forest-steppe and steppe of the Middle Irtysh region has been conducted by us from 1973 to the present. The analysis of literary sources has been carried out since the time of P.S. Pallas's travels in the region in 1871. In addition, information on the wetlands of the Irtysh region which is freely available on the Internet was used.Results. At the beginning of the 20th century, about 200 species of birds were recorded in the vicinity of Omsk, 125 of them being breeding species. At present about 150 species of birds have been recorded in Omsk and its environs. Of the 290 bird species of the Middle Irtysh region, 48 species (16.6%) belong among the natural hosts of influenza A viruses. Of these, at least 40 species are migratory and 25 species nest there. In addition to the prinicipal influenza virus host species, the list of birds of the Middle Irtysh region includes several species of scavengers and predators, as well as synanthropic bird species. These species may share habitat or food resources with the main host species of influenza viruses. Influenza A viruses can be transmitted between species either by direct or indirect contact through mechanical propagation or contamination of nutritional resources.Conclusion. As the 3 largest bird migratory flyways run through the Middle Irtysh region where there is a significant number of wetlands, the prerequisites are created for a mass simultaneous accumulation of different populations and species of migratory birds carrying viruses and, accordingly, a high probability of exchanging viral genomes with each other and their further spread to new regions.

AVIFAUNA OF THE ECOTOURISM PARK CACHOEIRA DO URUBU: A FRAGMENT OF ATLANTIC FOREST IN THE PERNAMBUCO ENDEMISM CENTER, NORTHEASTERN BRAZIL

The forest fragments that persist within a landscape formed by sugarcane matrix are fundamental for the faunal maintenance. Here, we present the list of bird species found in the Ecotourism Park Cachoeira do Urubu (PECUB), an Atlantic Forest fragment inserted in a landscape consisted by a sugarcane matrix in northeastern Brazil. Our consolidated list includes 117 bird species, of which 106 were recorded during our systematic surveys and other 11 species from a preliminary survey and an online database. When compared to larger fragments located in the same region (Atlantic Forest of Pernambuco), PECUB stands out for its species richness in such a small area (30 ha), with just over 40% of the number of species found in fragments 20 times larger, such as Dois Irmãos State Park. PECUB has three endemic taxa to the Pernambuco Endemism Center ( Picumnus pernambucensis , Hemitriccus griseipectus naumburgae , and Tangara cyanocephala corallina ) and one endemic to the Atlantic Forest ( Chrysuronia leucogaster bahiae ). Our study demonstrated the importance of PECUB as a suitable habitat for birds in a region threatened by forest fragmentation.

Preliminary evidence of tool use in an Australian magpie?

Abstract We investigated tool use in twelve wild-caught Australian magpies. When presented with a tool use apparatus consisting of two transparent walls with a food reward placed in-between, seven magpies pulled the stick out of the apparatus acquiring the food within. On one occasion, one magpie manipulated the removed stick, carried it back to the apparatus, dropped it between the two walls and proceeded to rake out the food within reach of its beak. We believe this observation is important for the field of comparative cognition as it (1) is the first study to report stick tool use in Australian magpies, and (2) shows a novel behaviour in a ground foraging bird that, as far as we know, do not naturally use tools for food extraction. This study provides preliminary evidence that Australian magpies may be added to the list of bird species that can use tools.

Avifauna of the Serra de Itabaiana National Park revisited: additions and deletions in a period of 15 years

The Serra de Itabaiana National Park (PARNASI) is known as an important conservation area in the ecotone between the Atlantic Forest and Caatinga in Northeast Brazil and is one of the main areas of fauna and flora studies in Sergipe. For this reason, there are some studies on its avifauna, which date back to its creation in 2005. However, after 15 years of establishment of PARNASI, an update of the inventory of birds is necessary due to adjustments in the management of the park. The present study aimed to update the bird inventory of the Serra de Itabaiana National Park, chronologically comparing the new ornithological records obtained, aiming to contribute to the knowledge and conservation of Sergipe's avifauna. The data were compiled from scientific publications, personal files and from documented records on a specialized website. The resulting list includes 227 bird species belonging to 49 families, including Thraupidae (28 species; 12.4%), Tyrannidae (25 species; 11.1%) and Accipitridae (17 species; 7.5%) as the most representative. The most representative guilds were insectivorous (87 species; 38.3%) and omnivorous (60 species; 26.4%), and by species independent of the forest environment (87 species; 38.3%). Fourteen bird species are threatened with extinction. Nine species are endemic to the Caatinga biome, eight to the Atlantic Forest and one to the Cerrado. We added 104 species to the first checklist produced for the PARNASI created in 2005, including Nyctibius grandis (Nyctibiidae), a new record for the state of Sergipe. PARNASI's updated list of bird species allows for a better assessment of its effectiveness in the conservation of the local avifauna, facilitating management actions that allow the coexistence and perpetuation of species over time.

The avifauna of a semideciduous seasonal forest fragment in the countryside of Barra Mansa, Rio de Janeiro, Brazil

The Atlantic Forest is one of the richest and most threatened biomes in the world, a fact that configures it as a global hotspot. We provide here a list of bird species recorded in the municipality of Barra Mansa (RJ), during ten years of ad libitum observations in a fragment of Semideciduous Seasonal Forest, one of the most devastated phytophysiognomies of this biome. We recorded 192 species, of which 107 present some degree of forest dependency, 22 that present migratory activity, 24 that are endemic in the biome or in Brazil and 5 that are relevant to conservation as they are almost threatened or vulnerable at some level (global, national or state). Regarding the trophic guild, there was a predominance of insectivorous (n=67) and omnivorous (n=58) species, which denotes some environmental quality, but pressured by an imminent anthropization. Given the obtained results, the importance of the analyzed fragment for the maintenance of the local biodiversity becomes evident.

Ecological constraints on elevational gradients of bird species richness in Tajikistan

The avifauna in Tajikistan has been widely studied for the last century, but specific work on species richness pattern along elevation gradients in Tajikistan is rarely investigated. Here, we reported the first study of bird species richness (BSR) in the high-altitude mountain systems (Tien Shan and Pamir-Alay) of Tajikistan which are very sensitive to the recent climate changes. We aim to explore the relationship of BSR pattern with elevation gradient and to determine the potential drivers underlying the patterns. We collected occurrence data from field surveys, published articles, and open access websites to compile a list of bird species along elevational gradients across the whole country. The BSR was counted by 100 ​m elevational bands ranging from 294 ​m to 5146 ​m. The patterns of BSR were calculated separately for five groups: all breeding birds, Passeriformes, Non-Passeriformes, large elevational range species, and small elevational range species. We calculated ecological and climatic factors of planimetric area, mid-domain effect (MDE), habitat heterogeneity (HH), mean annual temperature (MAT), temperature annual range (TAR), annual precipitation (AP), normalized difference vegetation index (NDVI), human influence index (HII), and human disturbance (HD) in each elevational band. A combination of polynomial regression, Pearson's correlation, and general least squares model analyses were used to test the effects of these factors on the BSR. A unimodal distribution pattern with a peak at 750–1950 m was observed for all breeding birds. The similar pattern was explored for Passeriformes and Non-Passeriformes, while species with different elevational range sizes had different shapes and peak elevations. For all the breeding birds and Passeriformes, BSR was significantly related to spatial, climate and human influence factors, while BSR of Non-Passeriformes positively correlated with all the given factors. First, second and fourth range classes of birds were significantly correlated with human influence factors. Moreover, large-ranged species had positive correlations with the mid-domain effect and weakly with habitat heterogeneity. We found that area, MAT and AP were the main factors to explain the richness pattern of birds, and the species richness increases with these three factors increasing. Multiple factors such as area and climate explain 84% of the variation in richness. Bivariate and multiple regression analyses revealed a consistent influence of spatial and climate factors in shaping the richness pattern for nearly all bird groups.

Особенности фауны и летнего населения птиц Ашинского природного биологического заказника (Челябинская область)

Based on the results of ornithological research conducted in the Ashinsky State Biological Reserve during several nesting seasons during the period 1990–2021, a preliminary list of bird species was compiled. It includes 107 species, the vast majority of which nest or are expected to nest. To study the bird population, the main types of habitats in the southeastern and southwestern parts of the reserve were examined. The highest indicators of species diversity (42 species) and population density (568.0 ind./km²) were found in avian associations of dark coniferousdeciduous forests. The communities of upland meadows were found to be the most impoverished (16 species and 227.5 ind./km²). Based on these indices, avian associations of floodplain habitats of the Biyanka River occupied an intermediate position (34 species and 385.5 ind./km²).). In the communities of the forest biotopes of the reserve, the chaffinch, redwing, tree pipit, willow tit, white wagtail, garden warbler, common rosefinch and greenish warbler prevailed. In the associations of upland meadows, the skylark, tree pipit, whinchat and yellowhammer dominated. Almost half (43 %) of the nesting species were representatives of the European fauna; the proportions of species of the Euro-Chinese, Siberian and Nomadic types are 19, 15 and 10 %, respectively

Using citizen science data to improve regional bird species list: A case study in Shaanxi, China

An accurate and updated regional bird species checklist is the foundation for biodiversity research and conservation. However, with ongoing climate and landscape changes, tracking the distributions of bird species is challenging, and expert-curated species lists are often limited regarding survey area and timeliness. Birdwatching in China is becoming increasingly popular, and observations recorded by citizen birders are quickly increasing as well. Assessing the value of these data for improving regional species lists and studying bird distribution needs a detailed and quantitative comparison of citizen science data and expert-curated data. We collected observation reports from the China Bird Report Center, the largest online open platform for sharing bird sightings in China. We focused on reports from 2016 to 2019 in Shaanxi Province. For expert-curated species lists, we used three sources: the latest bird field guide published by local ornithologists, the province list from Avibase, and a list generated from overlaying distribution range from BirdLife International with the outline of Shaanxi Province. In addition, we also compared the bird sighting coordinates with the species distribution maps from BirdLife International. Surprisingly, species checklists from different sources have considerable discrepancies, even among lists based on expert knowledge. Including birdwatching data, there are 616 bird species in total, but less than half of the species (294) appear in all checklists, and 17.2% of species are unique to one list. One hundred sixty-three species lack birdwatching records, but birdwatching identified 39 species new to the province. One hundred thirty-six bird species have sighting locations outside the distribution ranges from BirdLife International, suggesting that updates might be needed. The data also showed a clear trend of bird species shifting to higher latitudes than their traditional distributions. While being inadequate for generating a regional species checklist on its own, birdwatching data in China can be a valuable source for complementing expert knowledge. In particular, the coordinate information of bird sighting can help track species distribution shifts. On the other hand, comparing expert-curated lists to birdwatching data can generate a species list for targeted birdwatching and monitoring, which will improve the quality of the birdwatching data in the future.

BIRDS OF PARQUE ESTADUAL DO BIRIBIRI, CENTRAL ESPINHAÇO RANGE, BRAZIL

The Central Espinhaço Range forms a large biogeographical barrier that contains areas of ecological transition between two important conservation hotspots in Brazil: the Atlantic Forest and the Cerrado. This research aims to present the first consolidated list of bird species from Parque Estadual do Biribiri (PEBI) located in the Central Espinhaço Range at Minas Gerais state, southeastern Brazil. We recorded 172 bird species between August/November 2018 and January/April 2019, of which 15 are associated with the surrounding biomes (Caatinga, Cerrado and Atlantic Forest) and three species restricted to the southeastern Brazilian mountain tops. Among those species, four are considered globally Near Threatened and 41 species are listed under wildlife trafficking species, indicating the importance of conserving this area. Therefore, our results highlight the importance of PEBI and stress the importance of such transitional areas for maintaining diversity of birds in the Espinhaço Range.

Birds of Parque Nacional do Caparaó, Atlantic Forest, southeastern Brazil

Parque Nacional do Caparaó is located in the Serra do Caparaó in the southeastern region of Brazil. It lies on the border between the states of Espírito Santo and Minas Gerais. It is a large fragment of Atlantic Forest vegetation, with altitudinal variation from 630 to 2,892 m. We present an annotated list of bird species found in the park based on data collected from 2012 to 2018. We recorded 216 species, including 66 endemic, 22 threatened, and 17 newly recorded species. To complete the list of species, we added data available in several bibliographic sources and digital databases, bringing the total number of bird species in the park to 348 and including 98 endemic and 33 threatened species. This work is the first to present an updated list of birds for the park, and the data presented show the importance of this protected area for conservation of birds in the region.

Зміни видового складу куликів заходу України протягом історичного періоду зоологічних досліджень

Introduction. Information on historical changes in the fauna of geographical regions and biota habitats is important for understanding the processes that take place in ecosystems. The results of such an analysis in combination with modern research can indicate not only the global trends in changes of animal associations and the status of particular populations of species, but also reveal the reasons that caused the situation. Materials and discussion. The first lists of bird species in the 18th – early 19th centuries showed the nesting of 12 species of waders. However, during the 19th century 37 species of waders were found, 12 of which were nesting. 13 wader species were permanent migratory and 8 – rare migratory species. In the first half of the 20th century, there were 27 species of waders on the territory of Prykarpattia, and 25 in Volyn, among which there is a larger list of migratory and vagrant species in the foothills of the Carpathians. In the second half of the 20th century, 39 species of waders were described within the western regions of Ukraine, of which 17 were nesting, and four of them were recorded during the last decade. Conclusions. There are 42 species of waders (39 of them are recent) registered in the western part of Ukraine. Among them 17 species are nesting, 15 – migratory and seven – vagrant species. During the 20th–21st centuries, 23 species of waders, including only 7 nesting species, have not changed their status of stay. However, it has changed for 17 species: two species have disappeared; four – have become vagrant; the Ruff Calidris pugnax and the Marsh Sandpiper Tringa stagnatilis have changed their status from nesting to migratory. The Northern Lapwing Vanellus vanellus, the Green Sandpiper Tringa ochropus and the Wood Sandpiper T. glareola that were common, somewhere numerous bird, – have become few in numbers; and the Great Snipe Gallinago media and the Black-tailed Gotwit Limosa limosa – have become rare. The Jack Snipe Lymnocryptes minimus has become migratory. The nesting of sandpipers, with a southern area of distribution, in the western regions of Ukraine proves the fact of the global warming. However, the drop of the water level, drying out of wet meadows and swamps and, as a consequence, plant succession, have terminated the nesting of such species as the Ruff and the Marsh Sandpiper; the Black-tailed, the Great Snipe and the Wood Sandpiper become rare; the Northern Lapwing and the Green Sandpiper have become much less numerous.

Birds of Barandabhar Corridor Forest, Chitwan, Nepal

Long term monitoring of bird species was conducted in Barandabhar Corridor Forest, one of the important bird areas of Nepal (IBA). Bird species were identified by the point count method in transect surveys in two-time frames from 2002–2012 and 2015–2016 to obtain the bird species list. We compared our bird list with previously published (after 2000) checklists and compiled the updated checklist of birds of Barandabhar Corridor Forest. We documented 372 bird species belonging to 80 families in Barandabhar, including five Critically Endangered, three Endangered, eight Vulnerable, and 15 Near Threatened species. The Accipitridae family included the highest number of species (n= 32), followed by Muscicapidae (n= 30) and Anatidae (n= 18). Approximately, half of the total confirmed bird species were insectivorous. The list included 63% resident, 27% winter migratory, 7.5% summer migratory, and 2.9% passage migrant species. According to the habitat type, there were 181 species of forest, 74 species of wetland, 24 species of grassland, 70 species of open field, and 23 species of partially wetland birds. This updated checklist of bird species will serve as a reference guide for bird watchers, biodiversity researchers, and support managers for conservation effort; and can be used to track any changes in the composition of bird species in the future.

AVIFAUNA DO SOLO SAGRADO DO GUARAPIRANGA (SÃO PAULO, BRASIL)

AVIFAUNA OF THE SACRED SOIL OF GUARAPIRANGA (SÃO PAULO, BRAZIL): The avifauna of São Paulo, the largest Brazilian city, is one of the most studied in Brazil. However, some areas are lacking basic studies on the avifauna, including those under intense pressure from urban growth and deforestation. Here we present a list of bird species occurring in the Solo Sagrado do Guarapiranga (23°45’00”S, 46°44’00”W), an urban park in southern São Paulo. We carried out monthly bird surveys from July 2008 to June 2009, using transect method. After 250 hours of observations, we recorded 180 species, including 31 species endemics to Atlantic Forest and two species that are globally threatened. The insectivorous, omnivorous and frugivorous species were the most represented feeding guilds, with 70, 39 and 21 species, respectively. Occasional and rare species composed the community majority. The high species richness and the presence of threatened species indicate the importance of the area to the bird’s conservation in the largest Brazilian city.

Additions to the list of bird species in the Shushensky Bor National Park

This work includes additions to the existing annotated list of birds of the Shushensky Bor National Park, given in the book by ornithologist S.Yu. Petrov and senior state inspector S.V. Chumakov Birds of the Shushensky Bor National Park, published in 2020 in an electronic form. The paper provides general data on the avifauna of the national park, as well as the results of recent studies as of early 2021. The paper provides information on the sightings of 11 bird species that were not previously recorded in the park as a whole: Ptyonoprogne rupestris (Scopoli, 1769); Turdus merula (Linnaeus, 1758); Monticola saxatilis (Linnaeus, 1766); Ficedula hypoleuca (Pallas, 1764) аnd on individual cluster sites Mountain forestry: Podiceps cristatus (Linnaeus, 1758); Crex crex (Linnaeus, 1758); Charadrius dubius (Scopoli, 1786); Turdus obscurus J.F. Gmelin, 1789; Turdus iliacus (Linnaeus, 1766) and Perovsky forestry: Lanius borealis [excubitor] (Vieillot, 1807); Chloris chloris (Linnaeus, 1758), indicating the nature of their stay and biotopic distribution. The paper is illustrated with photographs taken on the territory of both clusters of the national park by employees of the Shushensky Bor National Park and by local birdwatchers.

ДОПОЛНЕНИЯ К ОРНИТОФАУНЕ ГОСУДАРСТВЕННОГО ПРИРОДНОГО ЗАПОВЕДНИКА «ОПУКСКИЙ» И СОПРЕДЕЛЬНЫХ ТЕРРИТОРИЙ

Information about the bird fauna of the reserve and adjacent territories, including their numbers, areas of permanent or temporary habitat, biotopic distribution, seasonal residence, and behavior is of interest in determining and clarifying the current conservation status of these species in a particular region. To do this, it is necessary to conduct faunal research, monitor species in General and compile (clarify) lists of bird species, in particular species of reserves and adjacent territories. State Naturе Reserve «Opukskiy» (further − the reserve) is a protected area that ensures the protection of unique natural complexes of the South of the Kerch Peninsula on the narrow coastal strip from Western tip of Kojashskoe lake to Chebakskaya beams (near Yakovenkovo). The location of the reserve determines its significance for the conservation of bird species that nest, migrate along the black sea coast and winter in the protected water area. The reserve plays an important role in maintaining breeding populations of rare and protected species of birds and are most numerous in the South of the Kerch Peninsula winter waterfowl, a transit district of rest and feeding for migratory birds and breeding areas of some species. Numbers in the last published list of bird fauna of the reserve [13] reflect the reliability of the presence of the species in the described territory. Baseline – 195 bird species in the reserve; 205 – taking into account adjacent areas [13] only in the reserve and adjacent areas was 241 and 263 species of birds, respectively, 46 and 58 species more above baseline. In this article, the author presents additions that provide information about the registration of new species of bird fauna in the reserve and adjacent territories and their status listed in the list. It contains information about 68 species of birds, 39 of which were registered in the reserve for the first time, 17 species of birds were found in neighboring territories, and 7 species were confirmed to be present in the reserve [13]. The State Nature Reserve «Opukskiy» plays an important role in maintaining breeding populations of rare and protected species of birds and are most numerous in the South of the Kerch Peninsula winter waterfowl, a transit district of rest and feeding for migratory birds and breeding areas of some species. Additions to the list of avifauna of the reserve and adjacent territories provide information on the species composition and state of the bird fauna, their current status and seasonal residence periods for the period from 1989 to 2020. 241 species of birds belonging to 132 genera, 53 families and 20 orders were registered on the territory of the reserve between 2011 and 2020, of which only 97 (39 %) nest relatively regularly. Among them – 39 new species for the reserve, and for 22 species – confirmed presence in neighboring territories. The total list of avifauna of the reserve and adjacent territories is 263 species of birds, which is 78 % of the total avifauna of the Crimea. Among the species registered in the reserve – 58 rare (37 species — in the red book of the Russian Federation and 51 species — in the red book of the Crimea). The results obtained are of theoretical and practical value for optimizing measures for the protection of rare birds in the conditions of increasing anthropogenic influence and global climate change.

Species diversity of birds in various high-rise complexes of the Sayano-Shushenskaya Dam area

This paper presents the inventory results of bird species diversity in the area of the Sayano-Shushenskaya Dam. The territory covers the mountainous area of the National Park Shushensky Bor, urban-type settlement Cheryomushki and its surroundings, including a section of the Sayano-Shushensky reservoir in the upper head water of the Sayano-Shushenskaya Dam and the Yenisei channel below the dam. A list of 216 species has been compiled, for 195 there is reliable confirmation of their habitat. The share of migratory-nesting species is 41%, sedentary 14%, migratory species about 31%, wintering and partially wintering 34%. Three species of waterfowl spend winter in the non-freezing areas of the reservoir. Within various high-altitude complexes 10 types of habitats have been identified, where on the basis of quantitative surveys numerous and common bird species have been identified. The maximum species richness was observed for the ornithocoenosis of the floodplain-valley complex. A cluster analysis of the lists of bird species for the selected habitats has been carried out. The analysis showed a high -diversity along the gradient of heights: forest communities of different altitude levels are similar in species lists by no more than 45%, intrazonal and alpine habitats have unique sets of species and are similar to the others by 29%. The lists of birds in subalpine meadows and high-mountain tundras were found to be identical. In winter there is a high correlation of the bird population between the floodplain-valley complex and anthropogenically disturbed territories. Three bird species were found outside the main range and 5 species within the main range, but not previously noted in this area by other researchers.
