Wildlife and Terrestrial Species

We provide rigorous and unbiased information on migratory birds, terrestrial and marine mammals, amphibians and reptiles, native plants, threatened and endangered species, wildlife disease, and on wildlife issues resulting from human activities. Our science contributes toward a more complete understanding of the Nation’s ecosystems and landscapes.

Prey Availability

Migratory wildlife need to balance the benefits of migration and reproduction with the physiological costs. This is particularly challenging in dynamic environments like wetlands, where food levels can vary greatly from year to year. For shorebirds in the Great Basin region, saline or terminal lakes provide essential habitats during their annual life cycle. To understand how changes in hydrology...

Seabirds and Forage Fish Ecology

Alaska's coastal and offshore waters provide foraging habitat for an estimated 100 million birds comprising more than 90 different species; from loons and seaducks that nest inland, to petrels and puffins that breed on islands off shore. All these birds depend on the sea to provide a wide variety of food types— from clams, crabs and urchins nearshore— to krill, forage fish, and squid offshore. The...

North American Waterfowl Management Plan

The North American Waterfowl Management Plan (NAWMP) represents the foundational and successful effort to manage waterfowl and migratory bird in North America. Continued success of NAWMP depends on maintaining relevance to partners and society over time. Social science research supports NAWMP by providing a better understanding of what people value regarding waterfowl and their habitats.

Tracking and Modeling the Population of the Louisiana Black Bear Using “BearTRAK”

"BearTrak" is an app that provides a central repository for Louisiana black bear tracking data, allowing managers to access information more quickly and reliably. USGS science was used in the decision to delist the species from the Endangered Species Act in 2016. Louisiana Department of Wildlife and Fisheries continues to monitor the Louisiana black bear population.

Monitoring Effects of Barrier Island Restoration on Piping Plovers in Louisiana

The federally threatened piping plover relies on sand-beach habitat year-round for nesting, foraging, and roosting, habitat that is particularly vulnerable to loss and degradation from coastal development, recreation activities, erosion, and sea-level rise.

Sea Duck Research

USGS research on sea ducks is designed to anticipate and address priority information needs of management agencies. Additionally, work is focused on individual species biology, migration and population status and trends because until recently, very little was known about sea ducks in Alaska.
