Human-caused disturbances are encroaching on natural areas and quantifying the relative effects of different types of disturbance, and whether they interact on a landscape to create additive or synergistic cumulative effects, will provide a better understanding of how wildlife are affected. We evaluated potential cumulative effects of industrial disturbance on habitat use of Barred Owls ( Strix varia ), Great Horned Owls ( Bubo virginianus ), and Boreal Owls ( Aegolius funereus ) in Alberta’s boreal forest using acoustic survey presence/absence data and boosted regression tree analysis to quantify the relative importance and interactions of different types of industrial disturbance, as well as forest age and composition. Barred Owls were more likely to be found in older mixedwood and deciduous forest, and we found evidence suggestive of cumulative effects from a negative effect of total human footprint on habitat use and an additional negative effect of roads. Great Horned Owls were found in older forest but were relatively tolerant of disturbance, and soft linear features (seismic lines, pipelines, transmission lines) had a positive effect on habitat use, possibly due to these types of disturbances creating suitable hunting habitat. Boreal Owls were more likely to be found in older coniferous forest, and the effects of disturbance did not show clear evidence of sensitivity or tolerance to human disturbance. Our results indicate the importance of forest age and composition on habitat use for these owls. Cumulative effects varied among owl species and were potentially more significant for Barred Owl; for the other two species the effects of industrial disturbance were relatively small and there was no evidence of cumulative effects. Our study also demonstrates that assessing cumulative effects of human disturbance on wildlife using boosted-regression trees can effectively help focus conservation efforts and can be used, for example, for evaluating the environment effects of new projects prior to their implementation","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70963571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The elusive nature of many marsh-breeding birds presents a challenge for effective population monitoring. The Great Lakes Marsh Monitoring Program (GLMMP), delivered by Birds Canada, addressed these challenges by concentrating survey efforts in marsh bird habitats and by using survey protocols aimed at maximizing marsh bird detections. GLMMP data suggest that numerous marsh bird species are declining. Here we consider the value of other avian monitoring programs to support our understanding of marsh bird population trends. Our goal was to compare the GLMMP, North American Breeding Bird Survey (BBS), and eBird with each other and with a combined survey, by evaluating frequency of detection, annual indices of abundance, and trend estimates. Using 23 years (1997–2019) of GLMMP, BBS, and eBird data, we calculated annual indices of abundance and trends for each survey for 18 marsh-breeding species across southern Ontario, Canada. We found that the GLMMP had more frequent detections, greater counts, and/or more precise trends for 8 species that breed almost exclusively in marshes, whereas 10 species with more variable habitat preferences had more frequent detections, greater counts, and/or more precise trends based on eBird and/or BBS. We found that combining counts from the GLMMP, BBS, and eBird increased the precision around trend estimates for 11/18 (61%) species; however, trend estimates for combined data tended to be positively biased relative to GLMMP trends for species that also frequent non-marsh habitats. We, therefore, provide evidence that combining citizen science data from multiple sources could increase the power to detect changes in marsh-dependent bird populations. Integrated datasets thus provide a promising avenue for future marsh bird conservation and management","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"53 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70963099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our understanding of how birds use human supplementary resources, especially artificial structures and patchy vegetation within urban areas, is limited. Our study compared the use of artificial structures versus natural vegetation by birds in built-up areas in the Cape Coast Metropolitan Assembly (CCMA) in the central region of Ghana. Using point count technique, we recorded bird species and the activities performed as well as the substrates they use in residential and commercial areas within the CCMA. We found that the mean bird abundance that used artificial structures did not differ significantly from those that used natural vegetation. The mean species richness that used artificial structures was found to differ significantly from those that used natural vegetation. The study also found a significant difference in activities performed by bird species and the substrate type used for daily life activities. Across species, birds showed preference for trees, shrubs, and natural vegetation structures for perching, feeding, and singing, whereas artificial structures such as billboards, telecommunication masts, ceilings of buildings, pylons, buildings, opening in street lights, and windows of buildings were preferred for nesting. These results demonstrate that although not a replacement for natural resources, artificial structures, when combined with natural vegetation, could contribute significantly to the survival of urban birds. Conservation practitioners could encourage urban mosaic landscapes of built and green spaces to conserve and restore populations of birds.","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70963535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evaluating the functional role of stopover sites for Neotropical migrants following passage across the Gulf of Mexico in autumn","authors":"Lauren Solomon, Antonio Celis-Murillo, Michael Ward, Jill Deppe","doi":"10.5751/ace-02150-180207","DOIUrl":"https://doi.org/10.5751/ace-02150-180207","url":null,"abstract":"Nearctic Neotropical migratory songbirds incur the highest mortality during migration. En-route, songbirds rely on a network of stopover sites to rest, refuel, and/or seek refuge during poor weather. Conservation strategies prioritize protection of sites that best meet these needs. However, the specific function of a stopover site is expected to vary in relation to factors, such as geographic location, surrounding landscape, and weather. To identify sites with the highest conservation value for migratory songbirds, a conceptual framework was independently developed to classify sites into three functional categories based on their geographic and landscape features: fire escapes, convenience stores, and full-service hotels. The few attempts to empirically validate this framework have focused on temperate stopover sites. We evaluated the framework by testing the hypothesis that a site’s geographic and landscape characteristics can predict its function. We used capture and radio-tracking data at an island and mainland site in the Yucatan Peninsula, Mexico to quantify mean and variance in daily capture rate, body condition, stopover duration, and departure behavior during autumn, with a focus on four species: Swainson’s Thrush (<em>Catharus ustulatus</em>), Red-eyed Vireo (<em>Vireo olivaceus</em>), Gray Catbird (<em>Dumetella carolinensis</em>), and Prothonotary Warbler (<em>Protonotaria citrea</em>). Our results supported our predictions that the island functions as a fire escape, providing refuge for very high numbers of birds after encountering crosswinds or headwinds over the Gulf of Mexico, and the mainland forest site serves as a full-service hotel. The framework provides valuable insight for strategic conservation planning and management of stopover sites for songbirds. We suggest future studies evaluate the framework’s application to non-forest bird species. Additionally, we encourage collaborative efforts to consolidate and integrate tracking data, capture data from migration banding stations, and radar-based bird density estimates across a broad geography to test the framework’s ability to inform conservation planning across species’ full migratory range.","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135442392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the distribution and abundance of species is a fundamental aspect of conservation biology. Species distribution models aim to predict distributions based on species observations and ecologically relevant information. To understand the contemporary distribution of Wild Turkeys ( Meleagris gallopavo ) in Ontario, we curated and collated Wild Turkey flock observations from eBird and iNaturalist submitted during winter 2018. We combined these with environmental predictors to build distribution models using MaxEnt and evaluated model fit using 10-fold cross validation. We also estimated total population size for this species under different modeling scenarios. The potential presence of unknown spatial bias in community science datasets is a complex problem often requiring context-specific statistical solutions. Data cleaning, sometimes referred to as thinning, filtering, or culling, is often proposed to manage this bias. As such, we tested the effect of data cleaning on model outputs and on subsequent analyses. We evaluated all models using area under the curve (AUC). We found building density to be the most important environmental variable followed by winter severity. We validated our habitat suitability estimates using fine-scale GPS data and found that data cleaning had no effect on habitat suitability estimates inside available Wild Turkey habitat or inside core-use areas, except at one site in 2012 (t = -2.2, P = 0.04, df = 14). Use of community collected data offers a cost-efficient and collaborative method to obtain data for species distribution modeling and management. We discuss implications for Wild Turkey management and present potential contemporary distribution maps for this species.","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70963130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
