[effects of environmental factors on the distribution of dominant wintering waterfowl species in east dongting lake wetland, south-central china].east dongting lake is one of the national nature reserves in china, and an important habitat for the wintering of waterfowls in china, and even, global wetlands. to study the relationships between waterfowl community and environmental factors is of vital significance in providing useful data and necessary information for the restoration of bird habitat. in the winters of 2010 and 2011, a survey was conducted on the wintering waterfowls in east dongting lake wetland, and canonical correspondence ...201323705401
mortality limits used in wind energy impact assessment underestimate impacts of wind farms on bird populations.the consequences of bird mortality caused by collisions with wind turbines are increasingly receiving attention. so-called acceptable mortality limits of populations, that is, those that assume that 1%-5% of additional mortality and the potential biological removal (pbr), provide seemingly clear-cut methods for establishing the reduction in population viability.we examine how the application of these commonly used mortality limits could affect populations of the common starling, black-tailed god ...202032724513
avian tuberculosis in naturally infected captive water birds of the ardeideae and threskiornithidae families studied by serotyping, is901 rflp typing, and virulence for poultry.avian tuberculosis was detected in one flock of 38 water birds of the families ardeideae (n = 20) and threskiornithidae (n = 18). mycobacterium avium subsp. avium (maa, serotype 1, genotype is901+ and is1245+) was more often (p = 0.01) detected in tissue and/or faecal samples in 18 (90.0%) birds form the ardeideae family: little egret (egretta garzetta), buff-backed heron (bubulcus ibis), great white egret (egretta alba), and bittern (botaurus stellaris) in comparison to two (11.1%) birds from t ...200717056210
unexpected dietary preferences of eurasian spoonbills in the dutch wadden sea: spoonbills mainly feed on small fish not shrimp.after an historical absence, over the last decades eurasian spoonbills platalea leucorodia leucorodia have returned to breed on the barrier islands of the wadden sea. the area offers an abundance of predator-free nesting habitat, low degrees of disturbance, and an extensive intertidal feeding area with increasing stocks of brown shrimp crangon crangon, the assumed main prey of p. leucorodia leucorodia. nevertheless, newly established and expanding colonies of spoonbills have surprisingly quickly ...201830997317
an integrated model for assessing heavy metal exposure risk to migratory birds in wetland ecosystem: a case study in dongting lake wetland, china.heavy metal contamination is present in wetland ecosystem worldwide, and quantitative risk assessment model is significant. in this study, an exposure model was integrated for assessing heavy metal exposure risk to migratory birds in dongting lake wetland (dtw). the concentrations of cr, cu, pb, cd, hg and as in water, plant, soil and fish were investigated from 9 migratory bird habitats. the results showed that exposure doses from drinking water pathways were very low. there was a sensitive are ...201525876031
effects of water level changes and wading bird abundance on the foraging behaviour of blacknecked storks ephippiorhynchus asiaticus in dudwa national park, india.the effect of water level changes and wading birds' abundance on the foraging behaviour of the blacknecked stork (bns) ephippiorhynchus asiaticus was studied from january 1995 to june 1997 in dudwa national park, uttar pradesh. our observations indicate that bns territoriality increased as food levels became depleted, resulting in increased rates of aggression towards intruders. chasing or aggression was more intense during the early period (february and march) than the late period (april, may a ...200111568483
migration tendency delays distributional response to differential survival prospects along a flyway.when populations grow or decline, habitat selection may change due to local density-dependent processes, such as site dependence and interference. in seasonally migrating animals, nonbreeding distributions may be determined through these mechanisms of density dependence, which we examine here at a hemispheric scale for a long-distance migrating bird. using summer and winter resightings of 2,095 eurasian spoonbills platalea leucorodia leucorodia that were ringed in the netherlands during 16 years ...201323535616
seasonal variation in density dependence in age-specific survival of a long-distance migrant.density dependence in vital rates is key to population regulation. rather than being constant, the strength of density dependence may vary throughout the year, but empirical evidence is limited. based on 22 years of data of color-banded birds from a recovering population of eurasian spoonbills platalea leucorodia leucorodia, we show, for the first time, seasonal variation in density dependence in survival of a long-distance migrating bird. combining resightings and dead recoveries at breeding, s ...201324358720
the cost of migration: spoonbills suffer higher mortality during trans-saharan spring migrations only.explanations for the wide variety of seasonal migration patterns of animals all carry the assumption that migration is costly and that this cost increases with migration distance. although in some studies, the relationships between migration distance and breeding success or annual survival are established, none has investigated whether mortality during the actual migration increases with migration distance. here, we compared seasonal survival between eurasian spoonbills (platalea leucorodia leuc ...201525589489
conspecific and not performance-based attraction on immigrants drives colony growth in a waterbird.local recruitment and immigration play an important part in the dynamics and growth of animal populations. however, their estimation and incorporation into open population models is, in most cases, problematic. we studied factors affecting the growth of a recently established colony of eurasian spoonbill (platalea leucorodia) and assessed the contribution of local recruits, i.e. birds born in the colony, and immigrants, i.e. birds of unknown origin, to colony growth. we applied an integrated pop ...201728502084
an age-dependent fitness cost of migration? old trans-saharan migrating spoonbills breed later than those staying in europe, and late breeders have lower recruitment.migration is a widespread phenomenon in the animal kingdom. on the basis of the considerable variation that exists between and within species, and even within populations, we may be able to infer the (age- and sex-specific) ecological trade-offs and constraints moulding migration systems from assessments of fitness associated with migration and wintering in different areas. during three consecutive breeding seasons, we compared the reproductive performance (timing of breeding, breeding success, ...201728543867
