ABSTRACT Alaska’s boreal birds face a rapidly changing environment, but we know little about shifts in migratory timing, particularly autumn. We used quantile regression to quantify long-term changes autumn capture date 21 passerines using 22+year datasets from two banding stations central Alaska. also quantified differences between sites and explored whether select climate indices during three periods of the annual cycle (breeding, post-fledge, migration) could predict median capture. Long-term migration were detected 86% taxa, 76% which exhibited advances (∼2-3 days/decade), long-distance migrants at one field site. However, site-specific unexpectedly highlight need for caution before extrapolating timing patterns over broad spatial extents. Warmer conditions breeding period (using AO index) associated with greatest number species (9). Collectively, hypothesize that immense size spatially-variable regions impact reproductive often resulting (with warming) occasionally delays cooling). Carry-over effects may therefore influence passage different populations, causing patterns, such as showing location, another. Finally, part broader effort anticipate reduce declines birds, our study underscores conservation value station data quantifying avian responses investigating drivers varied indices.

The significance of urban landscapes in safeguarding biodiversity is often disregarded, even though a considerable amount conservation focus directed toward hotspots where land conversion happening at the fastest pace. Maintaining areas not only benefits environment, but along with social, economic, and technological factors can increase stability systems to disturbance, concept known as “urban resilience”. In this synthesis paper, we explore ecological dimension resilience specifically on avian because birds are easy observe, relatively abundant, serve an indicator overall health environments. We first examine discuss role environmental stressors associated urbanization ongoing crisis. then provide overview characteristics environment that may promote birds, associations between social economic resilience. Finally, recommendations future research regarding strategies improve thus, whole, intersections ecology, ecosystem justice, planning. Since 68% world’s population projected live by 2050, it imperative scientists, planners, civil engineers, architects, others consider both cities natural anthropogenic stressors.

Abstract Bird–building collisions account for 365–988 million bird fatalities every year in the United States alone. Understanding conditions that heighten collision risk is critical to developing effective strategies reducing this source of anthropogenic mortality. Meteorological factors and regional migration traffic may increase rates but also be difficult disentangle from other effects. We used 5 years counts New York City examine influence nocturnal weather on with buildings during spring fall. found seasonally unfavourable winds impede visibility are important bird–building both seasons. Specifically, northerly westerly low southerly cloud ceiling height fall associated higher risks. Generally, these variables most strongly increased when was high, exception spring, which predicted triple compared high visibility, independent traffic. Synthesis applications : Although legislation turn off unnecessary lighting entirety seasons an ultimate goal, a proximate goal invaluable will predicting nights highest using information determine mitigation efforts could effective.

Summary Migratory birds are experiencing widespread population declines, underscoring the urgency of effective conservation actions. Long-term monitoring migratory birds, especially during migration, is crucial for such actions yet remains technically challenging. Bioacoustic nocturnal flight calls (NFCs) constitutes a promising technique to monitor migration. Such has increased in North America and Europe, but its application on East Asian–Australasian Flyway (EAAF) limited. Here, we present findings from an NFC project conducted at recording station central Beijing, China over four migration seasons. From around 3,350 hours effort, manually extracted identified 84,135 NFCs, involving least 111 species or groups that associated with wide range habitat types. We also found NFCs provided additional information species’ phenology comparison citizen science observation data. To our knowledge, this study first formal investigation bird using EAAF, serving as proof-of-concept case wider, long-term efforts traditionally understudied region. Our highlight significance incorporating into urban planning land management practices.

Every night during spring and autumn, the mass movement of migratory birds redistributes bird abundances found on ground day. However, connection between magnitude nocturnal migration resulting change in diurnal abundance remains poorly quantified. If departures landings at same location are balanced throughout night, we expect high turnover but little (stream‐like migration). Alternatively, migrants may move simultaneously spatial pulses, with well‐separated areas departure landing that cause significant changes day (wave‐like Here, apply a flow model to data from weather surveillance radars (WSR) quantify daily fluxes nocturnally migrating departing ground, characterizing stopover comprehensive synoptic scale framework.

Hummingbirds share biologically distinctive traits: sustained hovering flight, the smallest bird body size, and high metabolic rates fueled partially by nectar feeding that provides pollination to plant species. Being insectivorous sometimes serving as prey larger birds, they fulfill additional important ecological roles. Hummingbird species evolved radiated into nearly every habitat in Americas, with a core of diversity South America. Population declines some their are increasing risk extinction. Threats population health genetic just beginning be identified, including diseases hazards caused humans. We review disciplines health, disease ecology, genomics relate hummingbirds. appraise knowledge gaps, causes morbidity mortality disease, threats viability. Finally, we highlight areas research need provide ideas for future studies aimed at facilitating hummingbird conservation.

Abstract Citizen science is increasingly used in bird-window collision (BWC) research to collect data. However, few studies have collected BWC data from social media, and it remains unknown whether the quality comparable that of reported on dedicated platforms. To evaluate potential media as a citizen source for BWC, we Facebook well Taiwan Roadkill Observation Network (TaiRON), main platform reporting wildlife mortalities Taiwan. We compared decade (2012–2022) two platforms by examining nationwide geographical coverage species compositions observations. Overall, recorded 2,583 cases involving 153 Facebook, 1,000 104 TaiRON. More than half individuals were not found dead when observed, whereas all records TaiRON individuals. The top 80% cumulative generally similar between Moreover, sampling completeness both exceeded 95% (Facebook: 98.0%; TaiRON: 96.0%). our knowledge, this study among first through posts, results show quantity can be well-developed Taken together, may only serve promising tool collecting data, but also provide public education, which benefit bird conservation. Finally, integrating different sources helps paint more complete picture patterns, especially understudied areas such Asia.

We quantitatively assess the impacts of onshore wind turbines on local bird diversity using nationwide data in China. Results show that one standard-deviation increase (approximately 84 turbines) reduces abundance by 5.27% from mean value 5.38 and leads to a 3.7% reduction species richness 66 at county level. The negative originate resident birds, birds grasslands, waterfowl. Biodiversity protection helps safeguard against turbine installations. also find habitat loss after installations contributes biodiversity loss. Our results suggest fatalities caused are much smaller than those fossil-fuel power stations when deaths coal mining, plant operation, climate change accounted for.
