The main approach for the conservation of wintering waterbirds is through the identification of wintering sites, the assessment of their abundance and the determination of wintering population trends. The target sites are set for the implementation of management measures for both wintering species populations and sites falling within the Natura 2000 National Ecological Network. The aim of the present study is to identify the most important waterbodies in the country, based on data from the mid-winter waterbird census during the period 1977–2021.

Résumé :

Habitats provide essential space for migratory birds to survive and reproduce. Identifying potential habitats in annual cycle stages and their influencing factors is indispensable for conservation along the flyway. In this study, we obtained satellite tracking of eight swan geese (Anser cygnoides) wintering at Poyang Lake (28°57′4.2″, 116°21′53.36″) from 2019 to 2020. Using the Maximum Entropy species distribution model, we investigated the potential habitats distribution of the swan geese during their migration cycle. We analyzed the relative contribution of various environmental factors to h

SummaryLittle Bustard Tetrax tetrax surveys were conducted in Iran in autumn and winter from 2005/2006 to 2008/2009. Across northern Iran, Little Bustard presence was confirmed at 15 of the 84 sites visited during the surveys. Three main wintering regions were identified: the Moghan Plain in the north-west of the country, the Turkmen Sahra Plain at the south-east corner of the Caspian Sea and the Sarakhs Plain in the north-east, close to the Afghan border. Up to 10,050 individuals were counted in winter 2009 in the Moghan Plain, which was recognised as the most important area for wintering Lit

Résumé :

Abstract Using the latest dataset of the Hungarian Bird Ringing Centre, the aims of this study were to describe the monthly spatial pattern of woodcock occurrence and to assess the main wintering and breeding areas of the birds associated with Hungary in the last decade. Descriptive analyses were performed regarding the annual number of detections (ringing, recaptures and recoveries), and the relation between the annual number of woodcock ringers and the number of ringed birds was tested. Minimum convex polygons (MCP) were calculated for the detections of each month, and the variation of the m

Résumé :

Wetlands along the Bulgarian Black Sea coast are important wintering points for aquatic birds during the winter period, which is why the site is included in the mid-winter census, which is part of ornithological monitoring in our country. Based on the results obtained from it, an assessment of the ornithological status can be made and the environmental factors influencing it can be analyzed. The purpose of the study is to present a summary and analysis of census data on the species composition and number of waterfowl in the region of the Ramsar sites on the Bulgarian Black Sea coast for the pe

Résumé :

Hemeroby is a concept widely employed in assessment of the effect of human activities on vegetation. In this study, we apply the concept to a set of bird species occurring in a Mediterranean remnant wetland. The aim was to obtain an average hemeroby index for two seasonally related bird assemblages (i.e. breeding and wintering) based on the information related to two levels of plant hemeroby. In a grid of 47 cells 100×100 m-wide, we sampled the fine-grained distribution of plant communities (Braun-Blanquet method/cell) in parallel with birds (point count method; one point count/cell), assignin

Résumé :

Approximately 75% of the East Asian Flyway Tundra Swan Cygnus columbianus bewickii population winters in the Yangtze River floodplain, China. Historically the species was more widely distributed throughout the floodplain but now most of the population is confined to five wetlands in Anhui Province and to Poyang Lake in Jiangxi Province, where the majority (up to 113,000 birds) occur. Within-winter counts suggest that swans congregate at Poyang Lake before dispersing to other sites later in the winter. Counts show large between-year fluctuations, but suggest declines at Shengjin and Fengsha Lak

Résumé :

The effective protection of coastal and estuarine habitats requires reliable monitoring information on their use by waterbirds, and the use of small unmanned aircraft systems (UAS) may provide access to these habitats without disturbing birds. We evaluated the use of a rotary-wing UAS with a high-end consumer camera to identify and count wintering waterbirds at two coastal sites in British Columbia, Canada, in January 2015, and to map mudflat and marsh habitats. Photos of shorebirds, waterfowl, and seabird species were taken at varying altitudes, and disturbance of birds appeared minimal when

Résumé :

Habitat fragmentation and degradation in natural wetlands has resulted in declines in the populations of shorebirds in the Indian subcontinent. Shorebirds rely on these wetlands as wintering or stop-over sites along the southern extent of the Central Asian Flyway. Shorebirds are known to utilize agroecosystems as alternate foraging habitats. The suitability of agroecosystems as foraging areas for overwintering migratory shorebirds has not been well studied in the Indian subcontinent. We conducted a comprehensive assessment of published literature and compiled field observations to investigate
