Birds

Birds play a crucial role in many ecosystems and their conservation depends on a clear understanding of how environmental factors affect their survival and reproduction. CASC scientists are working to understand the connection between environmental factors and climate variables to help birds adapt to a changing climate. Explore our science on birds below.

Understanding Landscape Change in the Alaskan Arctic Coastal Plain and Yukon Kuskokwim Delta

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...

Climate Change Impacts to Migratory Birds: Development of a Climate-informed Integrated Population Model

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...

Examining the Responses of Species to Climate Change: Will Wildlife Face Biological Thresholds?

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...

Identifying Conservation Objectives for the Gulf Coast Habitats of the Black Skimmer and Gull-billed Tern

Many shorebirds and nearshore waterbirds are of conservation concern across the Gulf of America 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...

Identifying Critical Thresholds and Tipping Points for Priority Coastal Species in a Changing Future

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

Integrating Climate Change Research and Planning to Inform Wildlife Conservation in the Boreal Forests of the Northeastern U.S.

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...

Assessing the Impacts of Drought on Migratory Waterbirds in Key Conservation Regions of the Western U.S.

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...

Developing a Coordinated, Multi-Region Effort to Understand the Effects of Climate Change on Migratory Birds

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...

Informing Adaptation Strategies for Maintaining Landscape Connectivity for Northern Rockies Wildlife

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...

Relations Among Cheatgrass, Fire, Climate, and Sensitive-Status Birds across the Great Basin

The distribution and abundance of cheatgrass, an invasive annual grass native to Eurasia, has increased substantially across the Intermountain West, including the Great Basin. Cheatgrass is highly flammable, and as it has expanded, the extent and frequency of fire in the Great Basin has increased by as much as 200%. These changes in fire regimes are associated with loss of the native...

The Impact of Drought on Waterbirds and Their Wetland Habitats in California’s Central Valley

California’s Central Valley is a nexus for water resources in the state, draining the Sacramento and San Joaquin River watersheds. Urban centers, agricultural operations, and the environment all compete for limited water, and demand is expected to only increase as the population grows and agriculture intensifies. At the same time, the water supply is projected to decrease as temperatures...
