Birds

Phenology, or the timing of the annual cycles of plants and animals, is extremely sensitive to changes in climate. We know that plants and animals may adjust the timing of certain phenological events, such as tree flowering or migration, based on changes in weather. However, it’s important that we also understand how the timing of phenological events is changing over longer time frames, as climate

Climate change influences apex predators in complex ways, due to their important trophic position, capacity for resource plasticity, and sensitivity to numerous anthropogenic stressors. Bald eagles, an ecologically and culturally significant apex predator, congregate seasonally in high densities on salmon spawning rivers across the Pacific Northwest. One of the largest eagle concentrations is in t

Alaska’s Arctic Coastal Plain (ACP) and Yukon-Kuskokwim Delta (YKD) provide essential habitat for wildlife of management interest, including diverse communities of shorebirds and waterfowl. The low-lying ACP region is located on the North Slope of Alaska, and is rich with shallow lakes and ponds that form as a result of permafrost freeze-thaw cycles. This region is a primary nesting site for many

Migratory birds play a crucial role in many ecosystems (e.g. as pollinators and insect regulators) and are also valued by many bird watchers throughout the country and world. Effective conservation of migratory birds depends on a clear understanding of how environmental factors affect key demographic rates (e.g., survival and reproduction). This informational need is especially pressing in the con

Historical and projected climate data point toward significant changes in the future for the Northeastern and Midwestern U.S. These changes will include impacts to many species (like birds, fish, and mammals), ecosystems (like forests), and natural resources (like water) that humans appreciate and rely on. In order to prepare for these changes, land and resource managers need to be able to predic

Many shorebirds and nearshore waterbirds are of conservation concern across the Gulf of Mexico due to stressors such as human disturbance, predation, and habitat loss and degradation. Conservation and protection of these birds is important for the functioning of healthy ecosystems and for maintaining biodiversity in North America. Consequently, resource managers along the gulf need decision-aiding

A large portion of the U.S. population lives in coastal areas along the Atlantic and Gulf coasts and the Caribbean; however, our coasts are also home to many fish, wildlife, and plant species that are important for recreation, tourism, local economies, biodiversity, and healthy coastal ecosystems. Coastal habitats also provide protective ecosystem services to human communities, which are increasin

Northeastern boreal forests are an important habitat type for many wildlife species, including migratory birds and moose. These animals play vital roles in the boreal forest ecosystem, are a source of pleasure for bird and wildlife watchers, and contribute to tourism revenue for many communities. However, moose and migratory birds are thought to be particularly vulnerable to the impacts of climate

Migratory birds may be hit especially hard by climate change – particularly waterbirds that depend on wetlands as resting and feeding sites during their journey between breeding and non-breeding grounds. California’s Central Valley and the interior basins of southeastern Oregon and northeastern California provide some of the most critical wetlands resources to migratory waterbirds in the western U

Birds are appreciated and enjoyed by thousands of people and also play important roles in the ecosystem as predators, prey, and pollinators. Alaska provides important breeding ground for hundreds of migratory bird species that travel thousands of miles in their annual migrations between breeding and wintering spots. Understanding how climate and land use changes affect migratory bird populations

The U.S. Northern Rocky Mountains support a large number of native wildlife species, and survival of these populations depends on connected landscapes to support current migration and dispersal, as well as future shifts in species’ ranges. However, habitat fragmentation and loss threaten these connections. Land and wildlife managers across the U.S. are faced with decisions focused on reducing ris
