Quantitatively evaluating and monitoring augmentation efforts are critical for conservation success. We formally evaluated the success of two Western Burrowing Owl ( Athene cunicularia hypugaea ) population augmentation programs in Manitoba and British Columbia by assessing survival of breeding adults, fledging success, and return rates of fledglings. Manitoba’s head-starting program holds hatching year (HY) owls taken from the nests of previous captive-released pairs over winter. After being overwintered in human care, the HY owls are released in pairs as second year (SY) owls. British Columbia has a breeding and release program where owls are bred in facilities; their offspring are then held over winter, paired and soft-released in the spring. Both programs soft-release SY pairs that lay clutches in situ and young are referred to as “wild-hatched owls.” We investigated both individual owl and release site characteristics in relation to our success metrics. In Manitoba, breeding season survival averaged 81%, but no factors investigated had a significant effect on","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"54 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70963896","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}

{"title":"Habitat associations of Golden-winged Warblers and Blue-winged Warblers during the non-breeding season","authors":"David I. King, Michael E. Akresh, David Murillo, Ruth E. Bennett, R. Chandler","doi":"10.5751/ace-02465-180204","DOIUrl":"https://doi.org/10.5751/ace-02465-180204","url":null,"abstract":". The Golden-winged Warbler ( Vermivora chyrsoptera ) and Blue-winged Warbler ( Vermivora cyanoptera ) are both Neotropical migratory species of elevated conservation concern that overlap in distribution on their Central American wintering grounds, yet the extent to which they overlap in terms of habitat use is unknown, potentially hindering conservation efforts. We surveyed these two species along habitat and elevational gradients within a coffee-growing landscape during 2016 and 2017 in Yoro, Honduras. We used playback with a mobbing track known to enhance detections of female warblers, since examining sexual habitat segregation was another objective of our study. Habitat occupied by these two species differed, with male Golden-winged Warblers occurring in landscapes dominated by humid forest/coffee (forest with some dense shade coffee, which were indistinguishable with remote sensing at our sites) at higher elevations than male Blue-winged Warblers, which were positively associated with the amount of agriculture in the landscape. Six of seven female Golden-winged Warblers were encountered in shade coffee, however, this association was not significant, likely due to small sample size and low detectability. The association between male Golden-winged Warblers and humid forest/coffee and elevation, and contrasts in habitat use between male and female Golden-winged Warblers, are consistent with prior research in the region. Furthermore, the landscape associations of these non-breeding Vermivora species mirror their breeding landscape associations, with Golden-winged Warblers occupying more forested landscapes and Blue-winged Warblers occupying more agricultural landscapes. The use of shade coffee by female Golden-winged Warblers and Blue-winged Warblers suggests agroforestry could be a promising tool for conserving wintering populations of these species, although this result should be viewed with caution given that use of shade coffee is reported to elevate predation risk in other migratory 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":"70963907","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}

Gross","doi":"10.5751/ace-02519-180210","DOIUrl":"https://doi.org/10.5751/ace-02519-180210","url":null,"abstract":"Much of the biology of Black Swifts (<em>Cypseloides niger</em>) is poorly known due to the species’ mostly aerial existence and cryptic nesting habitat. Important aspects of the biology of the northern subspecies of Black Swift (<em>C. n. borealis</em>) have been described in the past two decades, but the difficulty in locating and accessing Black Swift breeding sites constrains a range-wide understanding of the species’ biology and abundance, and ultimately, the cause(s) of its population decline. The most widely used method to determine Black Swift breeding site occupancy is to monitor suitable nesting habitat during the last hours of daylight (evening surveys) to detect the presence of adults attending nests (i.e., flying to or from a cliff face). Potentially, dawn surveys could result in more detections if adults reliably leave their nests or roost sites at first light, after overnight attendance. Because the effectiveness of occupancy surveys has not been quantified, we compared detection rates between evening surveys and surveys in the first hours of daylight (dawn surveys) at nine known breeding sites in southern British Columbia in 2018. Next, we measured how detections varied over the dawn period at eight active breeding sites surveyed between 2018–2020 and seven breeding sites surveyed in August 2020 in southern British Columbia and western Alberta. At low light levels, 5.38 times the number of birds/minute were detected, on average, during dawn surveys, compared with evening surveys, with dawn to evening detection ratios as high as 8.93 at some sites. During dawn surveys, detections peaked 8 to 9 min before sunrise and declined rapidly as light levels increased after sunrise. We suggest using dawn surveys to determine breeding site occupancy and prioritize areas for nest searches, monitoring, and habitat protection to ultimately aid in conserving Black Swifts.","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"7 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":"135956719","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}

Determining the causes of population declines in migratory species requires knowledge of the threats faced throughout the entire annual cycle, necessitating accurate information about the migratory routes and non-breeding areas used by birds. We used light-level geolocators to identify the fall migratory routes and non-breeding distributions of adults breeding at the southern edge of the range in North Carolina (<em>n</em> = 5), where populations are declining, and at the core of the range in New Hampshire (<em>n</em> = 8), where populations are stable. The strength of migratory connectivity was moderate (mean = 0.42). New Hampshire birds used non-breeding areas broadly distributed across the Caribbean, whereas North Carolina birds used a restricted non-breeding area largely in the Dominican Republic. Suitable forest cover declined at a higher rate from 2000 to 2019 in the Dominican Republic than in other Caribbean countries (8.4% vs. 2–4% loss), exposing birds from the trailing edge to significantly higher suitable habitat loss on the non-breeding grounds compared with range-core birds. Birds from the two study populations also exhibited differing migratory routes, with North Carolina birds migrating south through Florida and many New Hampshire birds performing an overwater flight from the Carolinas to the Caribbean. Our results suggest the possibility that, at least for this species, forest loss on the island of Hispaniola could be exacerbating population declines at the southern edge of the breeding range in North Carolina.","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"62 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":"135262101","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}

It is the rarest of the six flamingo species on the planet and is one of the least studied flamingos. Little information exists about its annual cycle, including which wetlands individual Andean Flamingos use at different times of year, posing an obstacle to developing effective conservation planning for its populations. In 2020 and 2022, we attached GPS-enabled satellite transmitters to four Andean Flamingos in northwestern Argentina, tracking their movements throughout the year to provide an initial assessment of their movement patterns, including timing, rate, and distances of movements between wetlands. We found highly variable movement patterns between individual flamingos. After the breeding season, which they spend at high elevations, some flamingos moved northwards to overwinter in the central Andes of Bolivia, whereas others moved south to overwinter near sea level in the lowlands of central Argentina. All tracked flamingos moved rapidly between wetlands, some of which were used by multiple flamingos. One flamingo visited sites in Argentina, Bolivia, and Chile during one annual cycle, highlighting the need for international conservation cooperation. Given the growing threats to this species, including climate change and a recent, rapid increase in lithium mining, we call for further research on this and other flamingo species in the Andes.","PeriodicalId":49233,"journal":{"name":"Avian Conservation and Ecology","volume":"26 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":"135662610","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}
