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.

Assessing the Impact of Changing Water Resources on Migratory Bird Health and Management in the Central Flyway

There is a growing movement within natural resource management to view wildlife health as a cumulative outcome of many different factors, rather than simply the absence of disease. This inclusive understanding of health opens the door to management options that are more creative than traditional techniques aimed at preventing or mitigating pathogens. The public health field uses a...

Designing Climate-Resilient Habitat for At-Risk Species in the Southern Sierra Nevada Forest

Climate change adaptation research has made major advances over the last decade. For example, much is known about the impacts of climate change, many novel adaptation planning approaches have been developed, decision tools have become ubiquitous, and many novel adaptation options have been proposed. However, additional research is needed to demonstrate how these adaptation planning...

Developing a Climate Change-Informed “Conservation Opportunity Area” Portfolio for Sensitive Species’ Preservation

Integrating climate change into place-based conservation (i.e. focusing efforts on a specific place or region) presents a pressing challenge in the future success of biodiversity conservation. In particular, the broad effects of climate change can make it difficult to prioritize specific actions in specific places. Currently, Natural Heritage New Mexico, along with state and federal...

Enhancing the Reliability and Usability of Climate Change Information for Wildlife Action Plans in the Northeastern United States

The northeastern U.S. is home to a wide range of terrestrial and aquatic habitats, leading to a variety of interactions occurring between species and climate on multiple scales. Therefore, the most effective strategy to produce and deliver scientific climate information to resource managers is to align the scales of climate projections with the scales of resource management actions...

Identifying Effects of Weather and Land Use on Autumn and Winter Waterfowl Distribution Dynamics in the 21st Century

Waterfowl are of substantial economic and cultural importance, with over 1 million hunters contributing approximately $700 million in total expenditures to local and regional economies annually. However, shifts or expansions in waterfowl distribution driven by the interacting effects of a warming climate, changes in habitat resources, and altered anthropogenic pressures will present...

Informing Management of Waterfowl Harvest in a Changing Climate

The ability to effectively manage wildlife in North America is founded in an understanding of how human actions and the environment influence wildlife populations. Current management practices are informed by population monitoring data from the past to determine key ecological relationships and make predictions about future population status. In most cases, including the regulation of...

Mapping Salt Marsh Response to Sea Level Rise and Evaluating 'Runneling' as an Adaptation Technique to Inform Wildlife Habitat Management in New England

Loss of saltmarsh habitat is one of the biggest threats to coastal sustainability in the Northeast. Salt marsh has been identified as an essential fish and wildlife habitat, and loss of saltmarsh corresponds with precipitous declines in marsh-dependent wildlife. For example, the global population of Saltmarsh Sparrow is predicted to collapse within the next 50 years after experiencing a...

The Impact of Future Changes in Climate on Breeding Waterfowl Pairs in the US Prairie Pothole Region

The Prairie Pothole Region is recognized as one of the most critical breeding habitats for waterfowl in North America and is used by an estimated 50–80 % of the continent’s breeding duck population. The ongoing acquisition program of the U.S. Fish and Wildlife Service National Wildlife Refuge System has conserved approximately 1.3 million hectares of critical breeding-waterfowl habitat...

The Impact of Future Climate on Wetland Habitat in a Critical Migratory Waterfowl Corridor of the Prairie Pothole Region

The Prairie Pothole Region is recognized as one of the most productive areas for waterfowl in North America and supports an estimated 50–80 % of the continent’s duck population. This important habitat is threatened by climate change and continued land-use change. The goal of this research is to establish a framework for assessing future impacts of climate and land-use change on Prairie...

The Impact of Future Climate Variability on Shorebirds and Their Wetland Habitats in the South Central U.S.

Healthy wetlands provide buffers against drought, flooding, pollution, and other threats to humans and nature. Climate change imperils wetland health, including impacting the connections among wetlands that facilitate movements and prevent extinctions of wetland-dependent wildlife. One wildlife group of considerable conservation concern and vulnerability to climate induced wetland...

Understanding Impacts on Southeastern Grasslands from Climate Change, Urban Expansion, and Invasive Species

Much of the biodiversity of the southeastern U.S. is found in grasslands, including meadows, prairies, glades, and savannas. These grasslands provide vital habitat to a variety of plants and animals, but many grassland types have undergone over 90% loss due to fire suppression and urban sprawl. The remaining grassland patches—remnants—now face emerging threats from invasive species and...

An Alert System for Managing At-Risk Species in Cascadia under Climate Change

A rapidly changing climate and expanding human footprint is driving increased rates of landscape change in the Pacific Northwest. This makes it challenging for managers to know if and to what extent recovery goals and conservation plans for at-risk species need to be modified to account for changing habitat conditions. Addressing this challenge requires accurate, up-to-date information...
