Abstract:

The Huai He floodplain in Anhui and Jiangsu Provinces, an important component of the East Asian-Australasian Flyway (EAAF), sustains critical wetland habitats for migratory waterbirds, including four threatened species on the IUCN Red List: critically endangered <i>Aythya baeri</i> (Radde, 1863), endangered <i>Anser cygnoides</i> (Linnaeus, 1758) and vulnerable <i>Melanitta fusca</i> (Linnaeus, 1758) and <i>Aythya ferina</i> (Linnaeus, 1758). Despite its biogeographic significance as a transitional zone between the Yangtze and Yellow River floodplains, this region remains one of China's most u

Abstract:

The article presents data on waterbirds from the Red Data Book of Ukraine wintering in the Azov-Black Sea coastal wetlands during 2009‒2022. A total of 27 protected waterbird species were recorded during the International Waterbird Census. The average number of protected birds was 13,631 + 2,828 ind., the maximum — 35,768 ind. Detailed information on species composition and bird numbers is given for 14 wetlands, the most valuable for waterbirds.

Abstract:

Background: Libyan wetlands are diverse; the coastline of Libya in particular has different kinds of wetlands such as salt marshes, bays, lakes, lagoons and islands. These varieties in habitats provide good shelters and foraging sites for migratory birds during their journeys between Eurasia and Africa. Since the beginning of the Libyan winter census of waterbirds (Libya IWC) in 2005 which continued regularly until 2012, it had relatively the same performance in the number of covered sites. Since 2013, due to the security situation that Libya has experienced as a result of wars and conflict wh

We recently published an assessment of the wetlands in Bulgaria important for the wintering waterfowl species (order Anseriformes) based on the Mid-Winter Waterbird Census data (Stanchev and Nikolov 2025). However, self-reevaluation of the data led to the refinement of some of the values used and species names. The changes given below do not affect the results and their discussion described in the publication.

Abstract:

Data collection on wintering waterbirds in the wetlands of the Azov-Black Sea region of Ukraine began in the late 1980s, mainly thanks to the International Waterbird Census (IWC), which has become more extensive and regular since about 2005. This article is devoted to generalization of data on species composition, abundance of birds and their spatial distribution in that region based on the results of the winter census 2005–2022. The long-term dynamics of the waterbirds number and the peculiarities of the species distribution are mostly analyzed for abundant bird species. General information a

Summary In 2017, the International Waterbird Census (IWC) was carried out in Slovenia on January 14 and 15. Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 235 observers took part, 413 sections of the rivers and coastal sea with a total length of 1,427 km and 200 other localities (164 standing waters and 36 streams) were surveyed. The census was characterized by harsh winter conditions and high proportion of frozen water bodies. Altogether, 51,790 waterbirds of 61 species wer

Co-ordinated counts of waders across New Zealand have been undertaken in November and June since 1983; the consistent timing of counts aimed to reduce variation from the effect of seasonal changes in bird numbers. The Australian Shorebird census and the wider Asian Waterbird Census, however, are conducted in January, making direct comparison with the New Zealand counts potentially problematic, especially if an attempt is to be made to assess total flyway populations. Since 1998 waders on Farewell Spit (40°30.5 ́S, 172°45 ́E to 40°33.5 ́N 173°02 ́E) have been counted in February as well as in N

To compensate for quantitative limitations of the 'Winter Waterbird Census of Korea', we conducted a total of four bird monitoring via CS from 2021 to 2022. To use CS data alongside national data, we studied CS data quality and improvement utilizing (1) digit-based analysis using Benford’s law and (2) comparative analysis with national data. In addition, we performed bird community analysis using CS-specific data, demonstrating the necessity of CS. Neither C

The coastal areas of the island of Gotland in the center of the Baltic Sea is an important wintering site for waterbirds in Sweden. Gotland offers extensive areas of shallow feeding grounds and, due to its location, some open waters remain available even during harsh winters. Wintering waterbirds have been counted annually on the island since the start of the International Waterbird Census in 1967, with full coverage of all the inshore areas around the main island obtained during the years 1969–1978 and 2013–2020.

Information on migratory connections provide a basis for effective conservation efforts. The spatial connections between breeding and wintering areas are poorly known for many species. The connections become complicated in species that carry out additional migrations between their breeding and wintering areas. Common Shelducks (Tadorna tadorna, hereafter Shelducks) in western Europe perform an extensive moult migration after the breeding season. In this study, we examined the geographic connections between the breeding and wintering areas to identify ecological patterns, and estimate the influ

Abstract Background The Indo-Pacific sea urchin Diadema setosum has invaded the Mediterranean Sea and has spread along many locations in the southeastern part of the basin, where established populations exist on the shallow subtidal rocky shore. Diadema setosum is a ubiquitous species, of particular ecological importance due to the high levels of grazing pressure it imposes on benthic communities. Its biology, however, is not adequately studied, especially along its introduced range of distribution. The present study examines the population status of D. setosum outside its native range, in the
