Summary Wind power is a fast‐growing industry with broad potential to impact volant wildlife. Flight altitude key determinant of the risk wildlife from modern horizontal‐axis wind turbines, which typically have rotor‐swept zone 50–150 m above ground. We used altitudinal GPS data collected golden eagles Aquila chrysaetos tracked using satellite telemetry evaluate impacts turbines on and other raptors along migratory routes. Eagle movements during migration were classified as local (1–5 km h...
To maximize fitness, flying animals should flight speed while minimizing energetic expenditure. Soaring speeds of large-bodied birds are determined by routes and tradeoffs between time costs. Large raptors migrating in eastern North America predominantly glide thermals that provide lift or soar along slopes ridgelines using orographic (slope soaring). It is usually assumed slope soaring faster than thermal gliding because forward progress constant compared to interrupted when pause regain...
Soaring birds that undertake long-distance migration should develop strategies to minimize the energetic costs of endurance flight. This is relevant because condition upon completion has direct consequences for fecundity, fitness and thus, demography. Therefore, strong evolutionary pressures are expected energy minimization tactics linked weather topography. Importantly, minute-by-minute mechanisms use subsidize in variable largely unknown, large part technological limitations studying...
Large birds regularly use updrafts to subsidize flight. Although most research on soaring bird flight has focused of thermal updrafts, there is evidence suggesting that many species are likely multiple modes subsidy. We tested the degree which a large uses subsidy provide insights into decision-making underlies behaviour. statistically classified more than 22 000 global positioning satellite–global system for mobile communications telemetry points collected at 30-s intervals identify type...
Abstract Aim Climate change is expected to influence boreal bird communities significantly, notably through changes in forest habitat (composition and age structure), the coming decades. How these will accumulate interact with anthropogenic disturbances remains an open question for most species. Location Northeastern Alberta, Canada. Methods We used LANDIS‐II landscape model project landscapes, associated populations (72 passerine species), according three climatic scenarios (baseline, RCP...
Migratory connectivity is the degree to which populations are linked in space and time across annual cycle. Low indicates mixing of while high population separation or time. High migratory makes individual susceptible local environmental conditions; therefore, evaluating continuously a species range important for understanding differential trends revealing places times contributing these differences. The common nighthawk Chordeiles minor widespread, declining, long‐distance bird. Variable...
The 2023 wildfire season in Québec set records due to extreme warm and dry conditions, burning 4.5 million hectares indicating persistent escalating impacts associated with climate change. This study reviews the unusual weather conditions that led fires, discussing their extensive on forest sector, fire management, boreal caribou habitats, particularly profound effects First Nation communities. wildfires significant declines productivity timber supply, overwhelming management resources,...

Summary Animals respond to a variety of environmental cues, including weather conditions, when migrating. Understanding the relationship between and migration behaviour is vital assessing time‐ energy limitations soaring birds. Different modes have different efficiencies, are dependent upon types subsidized lift dependent. We collected GPS locations from 47 known‐age golden eagles that moved along 83 tracks. paired each location with determine meteorological correlates during spring fall as...
Abstract When wildlife habitat overlaps with industrial development animals may be harmed. Because and people select resources to maximize biological fitness economic return, respectively, we estimated risk, the probability of eagles encountering being affected by turbines, overlaying models resource selection for each entity. This conceptual framework can applied across multiple spatial scales understand mitigate impacts industry on wildlife. We risk Golden Eagles (Aquila chrysaetos) from...

Many studies project future bird ranges by relying on correlative species distribution models. Such models do not usually represent important processes explicitly related to climate change and harvesting, which limits their potential for predicting understanding the of boreal assemblages at landscape scale. In this study, we attempted assess cumulative specific impacts both harvesting climate-induced changes wildfires stand-level (e.g., reproduction, growth) in forest eastern Canada. The...
Top predators and scavengers are vulnerable to pollutants, particularly those accumulated along the food chain. Lead accumulation can induce severe disorders alter survival both in mammals (including humans) birds. A potential source of lead poisoning wild animals, especially scavengers, results from consumption ammunition residues tissues big game killed by hunters. For two consecutive years we quantified level exposure individuals a sentinel scavenger species, common raven (Corvus corax),...
Migration is costly in terms of time, energy and safety. Optimal migration theory suggests that individual migratory birds will choose between these three costs depending on their motivation available resources. To test hypotheses about use strategies by large soaring birds, we used GPS telemetry to track 18 adult, 13 sub‐adult 15 juvenile Golden Eagles Aquila chrysaetos eastern North America. Each age‐class had potentially different motivations during migration. During spring, the...
Abstract Background Weather can have both delayed and immediate impacts on animal populations, species evolved behavioral adaptions to respond weather conditions. has long been hypothesized affect the timing intensity of avian migration, radar studies demonstrated strong correlations between broad-scale migration patterns. How affects individual decisions about initiation migratory flights, particularly at beginning remains uncertain. Methods Here, we combine automated radio telemetry data...
Regional analyses assessing the vulnerabilities of forest ecosystems and sector to climate change are key considering heterogeneity impacts as well fact that risks, opportunities, adaptation capacities might differ regionally. Here we provide Integrated Assessment on Quebec's forests, a work involved several research teams focused commercial forests potential solutions. Our showed will alter ecological processes within forests. These changes result in important modifications landscapes....
Many migratory species are declining and for most, the proximate causes of their declines remain unknown. For many long-distance Neotropical songbirds, it is assumed that habitat loss on breeding or non-breeding grounds a primary driver population declines. We integrated data collected from tracking technology, community science remote sensing to quantify connectivity (MC), trends loss. quantified correlation between forest change throughout annual cycle songbird, Connecticut warbler (...
<title>Abstract</title> Under the current global biodiversity crisis, there is a need for automated and non-invasive monitoring techniques that are able to gather large amounts of information cost-effectively at scales. One such technique passive acoustic monitoring, which commonly coupled with automatic identification animal species based on their sound. Automated sound analyses usually require training detection algorithms. These algorithms annotated datasets mark occurrence sounds...
