Lead poisoning occurs worldwide in populations of predatory birds, but exposure rates and
population impacts are known only from regional studies. We evaluated the lead exposure …

Accounting for migration and connectivity of mobile species across the annual cycle can
present challenges for conservation and management efforts. The use of stable isotope …

Wind energy development has expanded rapidly in the past decade, becoming a significant
source of electricity, and a major element in a global strategy to reduce carbon emissions …

Wind power is a fast‐growing industry with broad potential to impact volant wildlife. Flight
altitude is a key determinant of the risk to wildlife from modern horizontal‐axis wind turbines …

To maximize fitness, flying animals should maximize flight speed while minimizing energetic
expenditure. Soaring speeds of large-bodied birds are determined by flight routes and …

Animals respond to a variety of environmental cues, including weather conditions, when
migrating. Understanding the relationship between weather and migration behaviour is vital …

Habitat selection studies are designed to generate predictions of species distributions or
inference regarding general habitat associations and individual variation in habitat use …

When wildlife habitat overlaps with industrial development animals may be harmed.
Because wildlife and people select resources to maximize biological fitness and economic …

Movement behavior and its relationship to habitat provide critical information toward
understanding the effects of changing environments on birds. The eastern North American …

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 …
