Regions L2 Landing Page Tabs

One of the major strengths of the Northeast Area is the enthusiasm and commitment of our scientists to produce the type of high quality science that the USGS is known for. Working together with our partners across the nation, we have the ability to provide complete, integrated and holistic environmental information that will produce the best results that we can achieve.

Toxicity of the Non-Steroidal Anti-Inflammatory Drug Diclofenac

One of the hallmarks of non-steroidal anti-inflammatory drugs (NSAID) is the difficulty in predicting potentially toxic effects.Diclofenac is one such NSAID that devastated Asian vulture populations when they fed upon carcasses of livestock treated with the NSAID diclofenac.Because these drugs are widely used, we studied the potential hazard of diclofenac in New World vultures.

Toxicity of Polybrominated Diphenyl Ethers and Other Flame Retardants to Wildlife

Flame retardants are a class of commonly used household and industrial products.  Because of widespread use, there is concern that their presence in the environment can potentially pose a hazard and risk to wildlife.

Contaminant Exposure and Effects—Terrestrial Vertebrates (CEE-TV) Database Summary Findings for Trust Resources in U.S. Coastal Habitats

Scientists and natural resource managers often seek information on the effects various environmental stressors on wildlife.To facilitate this activity, we created a database focused on environmental contaminant exposure and adverse effects in wildlife residing in coastal and estuarine habitat.The Contaminant Exposure and Effects-Terrestrial Vertebrates database is searchable and relatively...

Response of Migrating Birds to Hurricane Sandy

The Challaenge: Each autumn, millions of landbirds migrate southward from breeding areas in the U.S. and Canada. Because these migrations occur during hurricane season, the impacts of hurricanes on migrating birds and their en route resting and foraging sites (stopover sites) are a real concern. Hurricane Sandy occurred late in the landbird migration season. By the time the storm made landfall...

Nocturnal Bird Migration through the Central Appalachians

The Challenge: Concerns have arisen about the potential impacts of wind power development in the Appalachians on migrating birds, creating a critical need for information on their distribution and flight characteristics as they pass through the region. This study focuses on the spatial and temporal distribution of nocturnally migrating birds in the Central Appalachians (MD, VA, WV). The...

Radar Analysis of Fall Migration Stopover Sites in the Northeastern U.S.

The Challenge: Most landbird conservation efforts focus on protecting or enhancing breeding habitat. For migratory species, however, mortality is highest during the biannual migration periods. In fall, juvenile birds are making their first migratory flights; their success, and that of adult birds, depends on availability of suitable sites to safely rest and forage. Identifying important...

Poisoning of Migratory Birds at Contaminated Sites

The Challenge: The Department of the Interior (DOI) and the National Oceanic & Atmospheric Administration are trustees for a wide variety natural resources that belong to all Americans. Additional natural resources are overseen by Native American tribes, states, and other federal agencies. Migratory birds are an example of a trust species for DOI, under the US Fish and Wildlife Service....

Migration and Habitat Use by Seabirds in the Atlantic Flyway: Evaluation of Potential Impacts of Proposed Wind Farms

Overall, this study tracked movements of over 400 individuals of three species over the course of five years; one of the most comprehensive satellite tracking studies of marine birds ever conducted in Atlantic North America. Results provide a better understanding of how diving birds use offshore areas of the mid-Atlantic U.S. and beyond, and, in combination with results from other types of...

Effects of Dorsally Mounted Solar-powered Cellular GPS Transmitters on Diving and Foraging in Surf Scoters and Red-throated Loons

Several types of experimental attachment techniques were tested on each study species (Surf Scoters (Melanitta perspicillata), Red-throated Loon (Gavia stellata), and Northern Gannet (Morus bassanus)), including traditional Teflon-ribbon style harnesses, sutures, and harnesses made of silicone moulding. Silicone harnesses, which were deployed in 2014 and 2015,...

In-Air and Underwater Hearing Abilities of Seabirds

As diving foragers, sea ducks are vulnerable to underwater anthropogenic activities, including naval sonar activity and gillnet fisheries.  Bycatch in gillnets is a principle driver of mortality for sea ducks, killing hundreds of thousands of seabirds annually. To reduce gillnet bycatch, underwater hearing tests were conducted on affected sea duck species to assist with possible development of...

Vulnerability Assessment of Available Habitat for Wintering Black Ducks within the Refuge System in the Chesapeake Bay

American black duck (Anas rubripes) utilize inland and tidal freshwater and brackish marshes throughout the Chesapeake Bay and are considered to be an indicator species of the ecosystem’s health. Thus, conserving and increasing black duck habitats will subsequently benefit the general health of the bay. The goal of this study was to create a mechanistic model to determine the amount...

Endocrine Active Effects on Turtle Embryonic Development

The Challenge: Emerging contaminants may be in part responsible for recent endocrine disruption observed in fish in the Chesapeake Bay watershed. Endocrine active compounds implicated in the decline of fish populations may affect other wildlife as well. There are 6 species of turtles and 5 of snakes living within the main-stem and tidal areas of the Bay. As poikilotherms, reptiles are...
