In this study, we formalised the biotic predictors of nesting sites for four threatened Caucasian vultures by including species distribution models (wild ungulates, nesting tree species) as biotic layers in the vulture Maxent models. Maxent was applied in the R dismo package and the best set of the model parameters were defined in the R ENMeval package. Performance metrics were continuous Boyce index, Akaike's information criterion, the area under receiver operating curve and true skill statistics. We also calculated and evaluated the null models. Kernel density estimation method was applied to assess the overlap of vulture ecological niches in the environmental space. The accessibility of anthropogenic food resources was estimated using the Path Distance measure that considers elevation gradient. The availability of pine forests (Scots Pine) and wild ungulates (Alpine Chamois and Caucasian Goat) contributed the most (29.6% and 34.3%) to Cinereous Vulture (<em>Aegypius monachus</em>) nesting site model. Wild ungulate distribution also contributed significantly (about 46%) to the Bearded Vulture (<em>Gypaetus barbatus</em>) model. This scavenger nests in the highlands of the Caucasus at a minimum distance of 5–10 km from anthropogenic facilities. In contrast, livestock as a food source was most important in colony distribution of Griffon Vulture (<em>Gyps fulvus</em>). The contribution of distances to settlements and agricultural facilities to the model was 45%. The optimal distance from Egyptian Vulture (<em>Neophron percnopterus</em>) nesting sites to settlements was only 3–10 km, to livestock facilities no more than 15 km with the factor contribution of about 57%. Excluding the wild ungulate availability, the ecological niches of studied vultures overlapped significantly. Despite similar foraging and nesting requirements, Caucasian vultures are not pronounced nesting and trophic competitors due to the abundance of nesting sites, anthropogenic food sources and successful niche sharing.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44956496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although gut microbiota is an essential component of host health, the impacts of agricultural feeding on gut microbial community and pathogen transmission remain poorly understood. To fill this knowledge gap, we used 16S rRNA sequencing to characterize the fecal bacterial community of the Siberian Crane (<em>Grus</em> <em>leucogeranus</em>), a Critically Endangered species, that recently has shifted its foraging from largely <em>Vallisneria</em> tubers in Poyang Lake natural wetlands to crops (i.e., rice seeds and lotus rhizomes) in agricultural fields. We compared the bacterial communities between tuber foraging cranes and crop foraging cranes. Our results indicate that diet shift greatly modified the gut microbiota diversity, composition and function. Crop foraging cranes had higher microbiota diversity than tuber foraging cranes. The alteration in microbiota composition and function were correlated with change in food nutrition. Tuber (i.e., high in fiber) foraging cranes were enriched in Clostridiaceae with fiber digestion ability, and crop (i.e., high in carbohydrate) foraging cranes were enriched in bacterial taxa and functions related to carbohydrate metabolism. The flexibility of gut microbiota might enhance Siberian Cranes’ ability to adapt to novel diet and environment. However, many enriched families in crop foraging cranes were pathogenic bacteria, which might increase the susceptibility of cranes to pathogenic infection. Special caution should be taken to agricultural feeding waterbirds in Asia, where the widespread poultry-keeping in over-harvested rice fields might increase the transmission probability of pathogenetic bacteria among wild birds, domestic poultry and humans.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45101928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that the noise treatment did not alter the predation rates or survival probabilities of birds in artificial nests. However, the diversity and species composition of nest predators in artificial pine forests varied between breeding and non-breeding seasons, which may be explained by season-specific adaption of nest predators to bird nests or the unstable ecosystems of artificial forests. The diversity and species composition of nest predators differed between the different forests, probably because of differences in habitat heterogeneity. Predation time varied with treatment, season, and habitat, although most predators were nocturnal mammals. Niche segregation or changes in optimal foraging time may explain this phenomenon.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43114282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the stay in moulting sites, the grebes experience changes in organs and muscle size (atrophy, hypertrophy), and almost double their body mass, which has been suggested to act as an insurance against a collapse in prey availability in late autumn. During two years we collected blood samples from hundreds of individuals at one of the most important European moulting sites (the Odiel marshes, SW Spain), which is a highly polluted area due to mining drainage and chemical industry. We assessed the potential effect of moulting stage, day of the year and body condition on 16 blood biochemical parameters. Because of the changes in prey availability and body composition of grebes, we expected some physiological adjustments during moult. Elevated levels of cholesterol suggested that birds in active moult increased foraging effort to face the costs of moulting. There was increased amount of lactate dehydrogenase, corresponding to periods of breast muscle atrophy. Birds in active moult augmented protein ingestion, likely to account for the requirements of feather growth. We also show that the probability of fasting due to low prey availability increased late in the moulting season, as demonstrated by an increase in plasma <em>β</em>-hydroxy-butyrate.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49774712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
