Résumé :
Migrations of Waders (Charadrii) in the Middle Odra Valley (W Poland) Studies were conducted in 1994-2005, in the middle Odra valley (western Poland), between localities: Bytom Odrzański and Kunice (155 km). During research 1535 controls of different parts of valley were made. There were recorded 26 Charadrii species. Regular occurrence and migrations were observed only for a few of them: Little Ringed Plover (Charadrius dubius), Golden Plover (Pluvialis apricaria), Lapwing (Vanellus vanellus), Ruff (Philomachus pugnax), Common Snipe (Gallinago gallinago), Curlew (Numenius arquata), Redshank (Tringa totanus), Grenshank (T. nebularia), Green Sandpiper (T. ochropus), Wood Sandpiper (T. glareola) and Common Sandpiper (Actitis hypoleucos). There were a few observations of rare in Poland - Sociable Plover (Vanellus gregarius) - or usually uncommon inland species - Oystercatcher (Haematopus ostralegus), Great Snipe (Gallinago media), Bar-tailed Godwit (Limosa lapponica) and Whimbrel (Numenius phaeopus). Two features characterizing the waders' passages in the Lubusian part of Odra valley can be told. Firstly, the abundance of migrating birds is usually lower than in other areas, especially when comparing autumn numbers to big inland reservoirs and some ponds complexes. Secondly, the middle part of Odra valley plays more important role during spring than during autumn passage, especially for Lapwings and Golden Plovers.

Summary In the Czech Republic, 12 freshly dead birds belonging to four species were examined helminthologically during a period of 2015 – 2019. They were six Caspian gulls Larus cachinnans (Lariformes), three goosanders Mergus merganser (Anseriformes), two common snipes Gallinago gallinago, and one common curlew Numenius arquata (Charadriiformes). Concerning trematodes, five echinostomatoids species were found, namely Aporchis massiliensis (obtained from one positive Caspian gull), Echinoparyphium macrovitellatum (one positive from six Caspian gulls), Echinostoma academica (one positive common curlew), Echinostoma stantschinskii (one positive from two common snipes), and Echinochasmus mergi (one positive from three goosanders). All the five echinostomatoids species represent the first records for the helminth fauna of the Czech Republic; the fl ukes A. massiliensis and E. macrovitellatum are recorded for the first time in the Central Europe or the Europe at all, respectively.

Résumé :
Abstract In 2008, the IUCN uplisted the Curlew to near-threatened (NT) on its Red List. The bird’s population in Slovenia is localised and small, thus making it very important to be surveyed every year. Using the point count method, we recorded 9-12 breeding pairs in 2011 and 9-10 pairs in 2012 at Ljubljansko barje. Most of them were distributed in the eastern part of the area between the village of Lipe and the river Iščica, whereas only two occupied territories were discovered in 2011 and one in 2012 in the western part of the area. In a ten-year period, the area underwent agricultural intensification, with lowland non-intensive meadows declining by 50%. As a minimal requirement, meadows within the extent of the Curlew’s current distribution at Ljubljansko barje should be non-intensively managed (late first cut, no fertilizing or sowing of grass mixtures) and all other human activities prohibited from the beginning of March till the end of June (dog walking and training, ballooning, aircraft modelling). Based on the results of 2011 survey, Ljubljansko barje was designated an IBA for breeding Eurasian Curlews under the IBA criteria A1 and C1.

Résumé :
The Eurasian Curlew (Numenius arquata) is a species in decline, classified as near threatened (NT) worldwide, and vulnerable (VU) in Norway. In Akershus county, southeastern Norway, the population of breeding Eurasian Curlews was estimated at 50-60 pairs in 1982. No recent update exists of this population size estimate. In this study, we assessed the population size in 2017 in Akershus, and examined how the population size changed between 1971 and 2017 by using historical observation records of Eurasian Curlews. We estimated that there were 30 territories in Akershus in 2017 and found that the population declined by 47% since 1995 and 77% since 1971. In the period 1995-2017, the yearly rate of decline was 2.8%. We discuss possible reasons for the decline, such as intensive agricultural practices, high nest predation rates, and large-scale threats on the wintering grounds.

Résumé :
Представлены результаты анализа влияния гидромелиорации на 28 гнездящихся видов птиц лиманно-островного комплекса лимнофилов. Коренные преобразования фауны и населения птиц равнинного Крыма произошли во второй половине XX века в процессе формирования ирригационной сети Северо-Крымского канала. Восемь видов увеличили численность и область распространения в Крыму, из которых пять (Phalacrocorax carbo, Pehcanus onocrotalus, Ciconia ciconia, Numenius arquata, Remis pandelinus) появились на гнездовании. Смена гидрологического режима слабо отразилась на популяциях четырех малочисленных видов уток (Anas acuta, A. strepera, A. clypeata, Mergus serrator) и трех эвритопных видов куликов (Vanellus vanellus, Charadrius dubius, Haematopus ostralegus). Водохозяйственная деятельность привела к исчезновению колоний Limosa limosa и резкому сокращению гнездовой численности Motacilla feldegg. Переувлажнение прибрежных солончаков стало причиной уменьшения численности Charadrius alexandrinus. Трансформация околоводных биотопов вследствие ирригации незначительно повлияла на численность и распределение колоний чайковых ихтиофагов, тогда как динамика численности и распределение других трофических групп этой систематической группы определялись кормовыми условиями окружающих аквально-территориальных комплексов, ходом сукцессионных смен растительности, а также расширением площади островных систем, образовавшихся в результате затопления балочных понижений мезорельефа.

Résumé :
Autumn Passage of Waders (Charadrii) in the Middle Vistula Valley (Kaliszany, Central Poland) The phenology and dynamics of wader migration were studied at a stopover area in the middle Vistula Valley (Kaliszany ringing station, 51°05'N, 21°48'E, central Poland). The study was conducted during autumn passage seasons of 1993-1996 and 1999-2001. At this time 364 counts were done from mid-July to the end of October. Altogether 23 030 waders of 27 species were recorded within the study period. The most numerous species observed were: the Northern Lapwing (Vanellus vanellus) — 49% of all birds, Common Sandpiper (Actitis hypoleucos) — 16% and Greenshank (Tringa nebularia) — 9%. Species constituting ca 2-4% of all noted waders each were: the Dunlin (Calidris alpina), Spotted Redshank (T. erythropus), Wood Sandpiper (T. glareola), Curlew (Numenius arquata), Ruff (Philomachus pugnax) and Green Sandpiper (T. ochropus). The proportion of the remaining species did not exceed 2%. The pattern of autumn migration dynamics is presented for the dominant species.

Résumé :
SynopsisThe shorebird populations of the Moray Firth mudflats were studied between 1981 and 1985. Peak numbers of waders were found in midwinter when the total population may exceed 36,000 birds. More than 1% of the total northwest European population of oystercatchers (Haematopus osiralegus), redshank (Tringa totanus), bar-tailed godwit (Limosa tapponica) and knot (Calidris canutus) were recorded. Wildfowl reach peak numbers in October and November (approximately 45,000); numbers decline gradually thereafter as some birds move on to wintering sites elsewhere in Britain. Ringing and colour-marking studies showed that turnstone (Arenaria interpres), curlew (Numenius arquata), ringed plover (Charadrius hialicula), oystercatcher and redshank remained loyal to selected feeding areas within the Moray Firth while bar-tailed godwit, knot and dunlin (Calidris alpina) ranged widely throughout the winter.These observations are discussed in relation to the value of the Moray Firth to shorebirds and the problems posed by the reclamation of intertidal habitats and pollution of the intertidal areas.

The aim of this study was to contribute to the knowledge of avian diversity and breeding species in Türkiye. Observations were carried out in Iğdır Province within a total of 40 days spread throughout the migration and breeding periods of 2017-2018. Regional status and breeding codes were determined for each species. Some winter visitors have also been observed during the early stages of the spring migration. In the study, 192 species were identified belonging to 50 families from 20 orders and 58 residents, 83 summer visitors, 11 winter visitors, and 40 transit migratory birds. According to the result of the recording breeding behavior, 52 bird species were classified as confirmed breeders, 36 as probable breeders, and 70 as possible breeders. According to IUCN Red List, 10 globally threatened species (Haematopus ostralegus, Vanellus vanellus, Numenius arquata, Gallinago media, Gypaetus barbatus, Aegypius monachus, Circus macrourus, Aythya ferina, Streptopelia turtur, Neophron percnopterus) were observed. Aras Valley and Aralık-Karasu Wetlands are the most important areas for birds. The conservation of these areas is of high importance in the region for migratory birds.

Résumé :
Migration Dynamics and Seasonal Variation In the Biometrics of the Eurasian Curlew (Numenius arquata) Migrating through the Lower Vistula Valley (N Poland) in Autumn The aim of this study was to present data on the phenology of autumn migration of the Eurasian Curlew passing the lower Vistula valley and to determine whether there is a difference in biometrics between early and late migrants, which may reflect different timing of migration of birds from different parts of the breeding range. Studies were conducted in the lower Vistula valley in 2003-2008. Median date of migration fell into 9-13 August pen-tade. The migration dynamics showed major day-to-day changes in bird numbers and almost all of observed flocks migrated without staying in the study area. Moreover, only one bird was caught twice during the season. It indicates that lower Vistula valley is not an attractive stopover site for Eurasian Curlews. There were significant differences in the total head lengths, bill lengths and body masses of birds caught in different ten-days periods with larger and heavier birds occurring towards the end of the study period (ANOVA, Neuman-Keuls test: p < 0.05 in all cases). The gradual increase in the total head and bill lengths and probably also in body mass indicates that bigger birds from the eastern part of the breeding range migrate later than smaller birds, which breed in the west. There were no significant differences in wing length, tarsus length and tarsus with toe length (ANOVA, Neuman-Keuls test: p > 0.05 in all cases). Subspecies N. a. arquata and N. a. orientalis have similar wing length and in this study there were no significant differences for this measurement between following decades of the studied period. Collected data suggest that the wing length, which had clearly bimodal distribution, should be the best linear measurements for sexing at least juvenile Eurasian Curlews.

Résumé :
SummaryThe Parc National du Banc d’Arguin in Mauritania hosts the largest concentrations of coastal waterbirds along the East Atlantic Flyway. In spite of this importance, a review of the changes in the numbers of waterbirds in the area is lacking since the first complete count in 1980. Here we analysed the seven complete waterbird counts made since then, and the additional yearly counts made in one subunit (Iwik region) since 2003. We present evidence for changes in the community composition of waterbirds over the past four decades. Total waterbird numbers showed a decrease between 1980 and 2017, with only Great White Pelican Pelecanus onocrotalus showing a significant increase in numbers. Five species showed significant declines: Long-tailed Cormorant Phalacrocorax africanus, Red Knot Calidris canutus, Bar-tailed Godwit Limosa lapponica, Eurasian Curlew Numenius arquata, and Western Marsh Harrier Circus aeruginosus. In the remaining species, the variation in numbers between counts was too large, and the number of complete counts too small, for trends to be detected. The yearly counts at Iwik region also showed sharp decreases in the numbers of Red Knot, Bar-tailed Godwit, and Marsh Harrier, but not of Long-tailed Cormorant and Eurasian Curlew. A multivariate analysis revealed a significant change in species composition over time, which was caused mainly by changes in the species depending on the intertidal mudflats for feeding (generally in decline) vs. the species depending on fish and crustaceans in the sublittoral and offshore zones (often showing increases).

Résumé :
Ujjani wetland is a potential Ramsar site in Maharashtra, India with several satellite wetlands associated with it. The present study contributes to single large or several small habitat conservation theories by assessing wetland bird communities. Aquatic bird communities were assessed using area search and point count methods at Kumbhargaon (Ujjani), Bhadalwadi, Madanwadi, Palasdev, Pimple and Ravangaon wetlands between October 2011 and September2012. These are representative satellite wetlands around Ujjani. One-hundred-and-ten species of wetland birds across 12 orders and 29 families were recorded. Out of these, 66 were resident and 44 were found to be migrants. These birds represent 23% mudflat feeder, 16% upland feeder, 14% marsh feeder, 12% bird of prey, 11% surface feeder and fish eaters, while divers and wet meadow feeders were represented with 8.5% and 5% of the species, respectively. Among the birds recorded, Woolly-necked Stork Ciconia episcopus, Common Pochard Aythya farina, and Greater Spotted Eagle Clanga clanga belong to the Vulnerable category; while Eurasian Curlew Numenius arquata, Oriental Darter Anhinga melanogaster, Black-tailed Godwit Limosa limosa, Black-headed Ibis Threskiornis melanocephalus, Lesser Flamingo Phoeniconaias minor, Painted Stork Mycteria leucocephala, River Tern Sterna aurantia, and Great Thick-knee Esacus recurvirostris represent Near Threatened category on the IUCN Red List. The presence of these bird species underlines the importance and conservation priorities of a major as well as smaller satellite wetlands. Anthropogenic activities such as cattle grazing, fishing, sand and soil mining, land encroachment, urban development and tourism were observed as some of the threats to this wetland ecosystem as well as bird communities.

Résumé :
The breeding bird communities of 18 mires and surrounding forests in southeastern Norway were censused in 1976–77 and in 2015. We found that 53% of the mire species with sufficient data for analyses showed significant changes. Red-throated Diver Gavia stellata, Common Crane Grus grus, Wood Sandpiper Tringa glareola and Tree Pipit Anthus trivialis increased, whereas Northern Lapwing Vanellus vanellus, Black-headed Gull Chroicocephalus ridibundus, Meadow Pipit Anthus pratensis and Yellow Wagtail Motacilla flava decreased. There were also near significant decreases of Eurasian Curlew Numenius arquata and Eurasian Skylark Alauda arvensis. Population changes did not differ between short- and long-distance migrants. Species with marginal populations on mires declined more than mire specialist species, suggesting an indirect negative influence of problems in other habitats. Overall, there was a significant 19% decline in number of mire species, but a non-significant 7% increase in number of individuals. The bird community in the forests surrounding the mires showed significant population changes for 42% of the species with sufficient data for analyses, with increases in many resident forest species, but less so for migrants. Overall, there was a near significant 12% increase in number of forest species, and a significant 28% increase in number of individuals. Mire- and forest-associated species did not differ in population trends. Among short-distance migrants (mire and forest species combined), species wintering in agricultural habitats had more negative population changes than species wintering in other habitats. Thus, the breeding bird community on and around mires in this part of Norway has undergone large changes during the last 40 years. We discuss our results in relation to general trends of bird communities in northern Europe.

Résumé :
Khaparwas is a designated Bird Sanctuary under the administrative control of Wildlife Department of Government of Haryana in India vide notification dated 27th March, 1991. Its total area is 204.36 Acres. During the study period of four years (1997-2002), a total of 164 species of birds belonging to 16 Orders, 44 families were recorded from the Khaparwas bird Sanctuary in Jhajjar district in Haryana, India. Out of 164 species of birds, 104 species were residents, 45 species were winter migratory, 9 species of birds local migratory, 5 species were summer migratory and one species of bird was Straggler. In so far as, Abundance Status is concerned, 64 species of birds were Occasional, 60 species Common and 40 species were Uncommon. Birds like Black Ibis Pseudibis papillosa, Jungle Bush Quail Perdicula asiatica, Red Jungle Fowl Gallus gallus, Eurasian Curlews Numenius arquata, Eurasian Eagle Owl Bubo bubo, and Stork Billed Kingfisher Halcyon capensis were observed as specific to this area. Prominent migratory birds like Northern Shoveller Anas clypeata, Northern Pintail Anas acuta, Eurasian Wigeon Anas penelope, Garganey Anas querquedula, Spot-billed Duck Anas poecilorhyncha, Common Teal Anas crecca, Common Pochard Aythya ferina, Spotted Redshank Tringa erythropus, Eurasian Curlew, Common Snipe Gallinago gallinago and Common Greenshank Tringa nebularia were recorded in winter season only. In view of the present studies, it is strongly recommended that Khaparwas Bird Sanctuary in Jhajjar district in Haryana must be conserved in a better way, due to its proximity to Bhindawas Bird Sanctuary and Keoldeo National Park in Rajasthan and the rich avian diversity observed in present studies. Khaparwas has the potential to occupy a National Character as a Sanctuary.DOI: http://dx.doi.org/10.3126/ijls.v6i1.5597

Résumé :
Abstract Agriculture has a great impact on biodiversity in Europe. Populations of farmland birds are declining due to both intensification and abandonment of agriculture. The purpose of this study was to determine the effects of overgrowing on the diversity of birds at Cerknica Polje. Six vegetation types were identified on eight survey plots (15.2-31.6 ha each): Short grass - regularly mown wet meadows; Tall herbs - stands of Common Reed Phragmites australis and Reed Canary Grass Phalaris arundinacea; Sparse bushes - stands of low woody plants; Dense bushes - dense stands of bushes; Meadows with trees - mown meadows with scattered trees; Bushes with trees - hedges, trees and dense stands of bushes. In total, 34 species were registered. The heterogeneity of vegetation types correlated positively with the heterogeneity of bird species. The highest density of breeding territories and species was established in Bushes with trees, the lowest in Short grass. No species were registered in all vegetation types, and only Tree Pipit was recorded in five out of six types. Twelve species were registered in only one vegetation type. Cerknica Polje is an important breeding locality for species with the highest breeding density at the national level (e.g. Corncrake Crex crex, Curlew Numenius arquata, Skylark Alauda arvensis, Whinchat Saxicola rubetra, Sedge Warbler Acrocephalus schoenobaenus). These species breed in specific habitats with different stages of succession. A managing plan for the area should therefore combine abandoned plots in different stages of succession and large regularly mown areas. Abandonment of agriculture at Cerknica Polje has led to the emergence of areas with bushes in different succession stages. Efforts should be directed at preserving large complexes of mown wet meadows.

Résumé :
SummaryThe extent of intertidal flats in the Yellow Sea region has declined significantly in the past few decades, resulting in severe population declines in several waterbird species. The Yellow Sea region holds the primary stopover sites for many shorebirds during their migration to and from northern breeding grounds. However, the functional roles of these sites in shorebirds’ stopover ecology remain poorly understood. Through field surveys between July and November 2015, we investigated the stopover and moult schedules of migratory shorebirds along the southern Jiangsu coast, eastern China during their southbound migration, with a focus on the ‘Critically Endangered’ Spoon-billed Sandpiper Calidris pygmaea and ‘Endangered’ Nordmann’s Greenshank Tringa guttifer. Long-term count data indicate that both species regularly occur in globally important number in southern Jiangsu coast, constituting 16.67–49.34% and 64.0–80.67% of their global population estimates respectively, and it is highly likely that most adults undergo their primary moult during this southbound migration stopover. Our results show that Spoon-billed Sandpiper and Nordmann’s Greenshank staged for an extended period of time (66 and 84 days, respectively) to complete their primary moult. On average, Spoon-billed Sandpipers and Nordmann’s Greenshanks started moulting primary feathers on 8 August ± 4.52 and 27 July ± 1.56 days respectively, and their moult durations were 72.58 ± 9.08 and 65.09 ± 2.40 days. In addition, some individuals of several other shorebird species including the ‘Endangered’ Great Knot Calidris tenuirostris, ‘Near Threatened’ Bar-tailed Godwit Limosa lapponica, ‘Near Threatened’ Eurasian Curlew Numenius arquata and Greater Sand Plover Charadrius leschenaultii also underwent primary moult. Our work highlights the importance of the southern Jiangsu region as the primary moulting ground for these species, reinforcing that conservation of shorebird habitat including both intertidal flats and supratidal roosting sites in this region is critical to safeguard the future of some highly threatened shorebird species.

Résumé :
Data are presented on interspecific kleptoparasitism by Black-headed Gull Larus ridibundus, Common Gull L. canus, Herring Gull L. argentatus and Great Black-backed Gull L. marinus, collected in South Sweden from the late 1950s to the present day. The basis for the presentation is the various host species exploited by the four gull species. For each host species, information is given on species of gull kleptoparasitising it, seasonal occurrence of kleptoparasitism, details of behaviour and, when available, data on gulls’ success rates. The paper is intended as a sort of catalogue. For this reason, relevant literature is reviewed under each of the host-species headings. Gulls’ success rates varied between 55% for Black-headed Gulls and Common Gulls parasitising Northern Lapwings Vanellus vanellus, the most often observed kleptoparasitic association, and 15% on the few occasions that Black-headed Gulls parasitised Curlews Numenius arquata in grassland. When the same two gull species parasitised Common Starlings Sturnus vulgaris, their success rate varied with robbing tactic used (16% vs 45%). Beside the association of the two small gull species with Lapwings and Golden Plovers Pluvialis apricaria, the most frequently observed associations were those of Herring Gulls with Common Eiders Somateria mollissima and Great Black-backed Gulls and Herring Gulls with diving fish-eaters (Great Cormorant Phalacrocorax carbo, mergansers Mergus spp.). Kleptoparasitism often occurred during periods of food scarcity, being most common in harsh winter conditions (the two large gull species) and during cold spells in early spring (some associations of the two small gull species). As in other studies, gulls’ success rate was strongly dependent on the size of hosts’ prey, and thus, normally on handling time. It is suggested that success rate can often be used as a substitute for profitability in studies of kleptoparasitism.

Résumé :
SummaryIllegal killing/taking of birds is a growing concern across the Mediterranean. However, there are few quantitative data on the species and countries involved. We assessed numbers of individual birds of each species killed/taken illegally in each Mediterranean country per year, using a diverse range of data sources and incorporating expert knowledge. We estimated that 11–36 million individuals per year may be killed/taken illegally in the region, many of them on migration. In each of Cyprus, Egypt, Italy, Lebanon and Syria, more than two million birds may be killed/taken on average each year. For species such as Blackcap Sylvia atricapilla, Common Quail Coturnix coturnix, Eurasian Chaffinch Fringilla coelebs, House Sparrow Passer domesticus and Song Thrush Turdus philomelos, more than one million individuals of each species are estimated to be killed/taken illegally on average every year. Several species of global conservation concern are also reported to be killed/taken illegally in substantial numbers: Eurasian Curlew Numenius arquata, Ferruginous Duck Aythya nyroca and Rock Partridge Alectoris graeca. Birds in the Mediterranean are illegally killed/taken primarily for food, sport and for use as cage-birds or decoys. At the 20 worst locations with the highest reported numbers, 7.9 million individuals may be illegally killed/taken per year, representing 34% of the mean estimated annual regional total number of birds illegally killed/taken for all species combined. Our study highlighted the paucity of data on illegal killing/taking of birds. Monitoring schemes which use systematic sampling protocols are needed to generate increasingly robust data on trends in illegal killing/taking over time and help stakeholders prioritise conservation actions to address this international conservation problem. Large numbers of birds are also hunted legally in the region, but specific totals are generally unavailable. Such data, in combination with improved estimates for illegal killing/taking, are needed for robustly assessing the sustainability of exploitation of birds.

Résumé :
The creation of reservoirs in river valleys for the accumulation of fresh water has been and remains an important issue around the world. This process has both positive and negative consequences for people and nature. Significant changes in the regime of rivers and their valleys, flooding of meadows and forests, flooding of soils and changes in the composition of flora and fauna of adjacent territories are taking place. In this article, we consider the restoration of the biodiversity of a site of disturbed lands after the creation of one of the first large reservoirs in Europe – the Dnieper (Zaporozhe) on the River Dnieper, which has existed since 1933. The territory of the Samara floodplains was formed on the floodplain of the mouth of the Samara River, as a result of which the territories of various forest, meadow and bog biotopes were flooded. For almost 90 years, new biotopes have been developing, and populations of plant and animal species, especially waterfowl, have been renewed and enriched. In the conditions of climate change and anthropogenic pressure, the existence of this territory has fallen into question. To control the conservation of biodiversity, it is necessary to apply various management methods, one of which is creation of nature reserves. The article presents the results of a complex of scientific studies that were carried out during the zoning of the regional park Samara Plavni to improve the management of the protection of water areas and river banks. We have investigated: hydrological features, species diversity of the flora and coenotic diversity of the vegetation, fauna of aquatic invertebrates, and terrestrial vertebrates. Zoning of the Regional Landscape Park was based on the composition of stable components of ecosystems. When applying the protected regime in different zones, conditions will be created for the preservation of habitats of species, including those protected in Europe: higher plants (Senecio borysthenicus (DC.) Andrz. ex Czern., Tragopogon borystenicus Artemcz.), reptiles (Emys orbicularis (Linnaeus, 1758), Vipera renardi (Christoph, 1861)), birds (Aythya ferina (Linnaeus, 1758), Vanellus vanellus (Linnaeus, 1758), Haematopus ostralegus Linnaeus, 1758, Numenius arquata (Linnaeus, 1758), Alcedo atthis (Linnaeus, 1758), Lanius excubitor (Linnaeus, 1758)), mammals (Lutra lutra (Linnaeus, 1758)). Such changes would increase the implementation of the reproductive potential of all species without exception in the studied ecosystems.

Résumé :
SummaryThe natural coastal wetlands of the East Asian-Australasian Flyway (EAAF) are disappearing at alarming rates, leading to rapid declines of many populations of waterbirds in the most species-rich flyway in the world. The identification and assessment of possible alternative habitats that may buffer the loss of natural wetlands should, therefore, be a priority for the conservation of migratory waterbirds using this flyway. Coastal saltpans are functional wetlands that support large numbers of waterbirds worldwide. The Nanpu Saltpans in the northern Bohai Bay of the Yellow Sea in China are one of the largest (290 km2) saltpan complexes in the world. In this paper, we document the value of the Nanpu Saltpans for supporting waterbirds. The surveys, carried out from 2013 to 2016, included waterbird counts in the saltpans (93 km2) at high and low tide and on the adjacent natural tidal flats (57 km2) at low tide. Of the 89 waterbird species recorded, 27 had maximum counts exceeding the 1% threshold value of estimated flyway populations. The maximum counts of waterbirds in northward migration and southward migration in the Nanpu Saltpans were 96,000 and 93,500, respectively, including both foraging and roosting birds; these figures do not account for turnover, so the total number of birds using the site is likely to be higher. The maximum counts on the adjacent tidal flats at low tide amounted to 73,000 and 20,000 waterbirds during northward and southward migration, respectively, and most of them were foraging birds. In the boreal winter, few birds fed in the saltpans, but several thousand fed on the tidal flats. Waterbirds used the inland ponds (2.0–18.0 km from the intertidal area) mainly for feeding both during low tide and high tide and used the nearshore ponds (0.3–4.3 km from the intertidal area) mainly for high-tide roosting. Some species, such as Black-tailed Godwit Limosa limosa, Marsh Sandpiper Tringa stagnatilis, Pied Avocet Recurvirostra avosetta, and Black-winged Stilt Himantopus himantopus, occurred mainly in the saltpans; other species preferred tidal flats, such as Red Knot Calidris canutus, Great Knot Calidris tenuirostris, Bar-tailed Godwit Limosa lapponica, Eurasian Curlew Numenius arquata, Relict Gull Larus relictus, and Grey Plover Pluvialis squatarola. This study clearly demonstrates the joint ecological function of the Nanpu Saltpan complex and adjacent tidal flats as a key staging area for waterbirds in the EAAF, and as such both urgently warrant protected status.

Résumé :
La Reserva de la Biosfera de La Mancha Húmeda es el principal grupo o red de lagunas de interior de la Península Ibérica donde poblaciones de aves acuáticas, con prioridad de conservación a nivel europeo, nidifican e invernan constituyendo un punto caliente para la conservación de la biodiversidad. En la actualidad, es uno de los complejos de humedales más amenazados en España y Europa debido a las actividades humanas, principalmente la agricultura, hasta el punto que en el año 2008 se propuso su descatalogación como Reserva de la Biosfera. Entre enero de 2007 y diciembre de 2010 se ha realizado un censo mensual en 10 lagunas localizadas en el Campo de San Juan (SE de Toledo, SO de Cuenca y NE de Ciudad Real) dentro de la Reserva de la Biosfera, presentando en este trabajo los resultados del seguimiento de las 12 especies catalogadas como SPEC 1 y 2 (Birdlife International, 2004) reconocidas en este espacio geográfico. Los resultados muestran que dos especies, el porrón europeo (<em>Aythya ferina)</em> y la cigüeña común (<em>Ciconia ciconia</em>) son comunes y se encuentran ampliamente distribuidas en las lagunas estudiadas, siendo el porrón europeo la especie que ha mostrado el mayor tamaño poblacional. Cuatro especies (<em>Ciconia</em> <em>nigra</em>, <em>Platalea</em> <em>leucorodia</em>, <em>Marmaronetta</em> <em>angustirostris</em> y <em>Numenius</em> <em>arquata</em>) tienen una presencia ocasional y con muy bajos tamaños poblacionales, utilizando estas lagunas como lugar de descanso en sus rutas migratorias o movimientos dispersivos El resto de especies (<em>Vanellus</em> <em>vanellus</em>, <em>Limosa</em> <em>limosa</em>, <em>Tringa</em> <em>totanus</em> y <em>Philomachus pugnax</em>) presentan escasos efectivos demográficos, utilizando las lagunas de manera ocasional y distribuyéndose de manera discontinua. Cinco lagunas (Manjavacas, Camino de Villafranca, La Veguilla, Salicor y Pedro Muñoz) han presentado en algún momento del periodo de seguimiento de 8 a 10 de las especies inventariadas, todas ellas bajo protección legal como Reserva Natural. La profundidad de la lámina de agua, la presencia de orillas adecuadas, el desarrollo de helófitos, la presencia de nutrientes y las características hidroquímicas parecen condicionar el uso de las lagunas por las diferentes especies.

Résumé :
Between the end of February 2007 and mid-February in 2008, 73 systematic surveys of waterbirds and raptors were carried out during 10-day periods at Cerknica polje (Southern Slovenia). The main objectives of our research were: to ascertain the abundance and temporal dynamics of the species occurring here, to specify their status, to make a comparison with the past period of systematic data gathering in the 1991-1992 period, to present estimates of the breeding, migrating and wintering populations, as well as to make, on these bases, a nature-conservancy evaluation of the area. Other ornithological data, acquired till the end of 2010, were gathered as well. Between the beginning of May and the beginning of September 2007, the water in the area virtually ran dry (it was retained only in the channels of the streams), while the surface itself was partially or fully icebound from mid-November 2007 till the beginning of February 2008. By the end of 2010, a total of 129 waterbird and raptor species were recorded at Cerknica polje, while in the 2007-2008 period 83 were registered. Dynamics of the species occurrence with more than nine observations made in the area is presented in a greater detail in the species overview. The breeding status was held by 27 bird species, while further seven were forage guests that bred in the vicinity of the study area. Most of the species (118) had the status of passage visitor, whereas those with the status of summer visitor (34) and winter visitor (40) were fewer. Among the recorded species, 34 were accidental and 21 rare visitors. There were 16 winter and seven summer residents, while year-round residents were six. In all 10-day periods of the research period, four species were recorded: Mallard Anas plathyrhynchos, Grey Heron Ardea cinerea, Buzzard Buteo buteo and Kestrel Falco tinnunculus. In more than 90% of 10-day periods, the Great Egret Ardea alba was recorded as well. In the 2007-2008 period, two species were eudominant (Mallard 27.2%, Buzzard 10.1%), whereas another two were dominant (Garganey Anas querquedula 7.4%, Coot Fulica atra 6.4%). Most individuals were registered at the end of March and in early April (up to 1,978 ind.), whereas the greatest numbers of species (48) were recorded in mid-April. Between May and August, the numbers of individuals and species were low owing to the dried up lake. The smallest area of occurrence was occupied by the Cormorant Phalacrocorax carbo and a group of ducks of the genera Aythya, Bucephala and Mergellus. Gulls, egrets, herons, waders, harriers Circus sp. and the Red-footed Kestrel Falco vespertinus occurred in the greater part of the research area. 10 breeders fulfilled the criteria of the species of the greatest conservation importance, two of which (Ferruginous Duck Aythya nyroca and Curlew Numenius arquata) are species of global conservation concern, whereas seven are of conservation concern on a European scale. Among non-breeders, 14 waterbird species and raptors occurred in significant numbers (> 0.1% biogeographical population), five of which occurred at least occasionally with more than 1% of their biographical population. Two species (Red-necked Grebe Podiceps grisegena and Snipe Gallinago gallinago) breed in Slovenia only at Cerknica polje, while further six species have here at least 40% of their Slovenian breeding population
