Bird and Terrestrial Species Conservation

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 stopover...

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. When wild...

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, offered the best balance between...

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...

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...

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 of...

Once common to forest and backyard habitats, the eastern box turtle ( Terrapene carolina) has declined sharply.

The Challenge: Accurate comprehensive information on current names of species and subspecies, their distributions, and means for their identification are required for effective conservation, management, scientific study, and enforcement of laws governing take, protection, and commerce. For the South American continent, up-to-date references containing this information have not been available until...

The Challenge: Although wildlife strikes have been investigated for decades, awareness of the dangers involved with aircraft/wildlife collisions was brought to the attention of the public when US Airways Flight 1549 struck what turned out to be a flock of Canada geese in 2009. Wildlife/aircraft collisions can be hazardous not only to the animal(s) involved, but also to people and costly equipment...

The Challenge: How can we preserve and maintain evidence from our scientific past and continue to smartly expand that resource to help scientists find the answers to the questions and challenges they will face in the future?

The Challenge: The Federal Aviation Administration has long relied on the expertise provided by the Smithsonian Feather Identification Lab for identification of bird remains recovered from bird-aircraft (birdstrike) collisions. Recently, these identifications are increasingly reliant on data from mitochondrial DNA. While generally successful in delimiting species, mitochondrial DNA is not...

The Challenge: Accurate taxonomic delineation of species and subspecies provides the biological and legal foundation for effective conservation action, whether by domestic resource management agencies or by other countries throughout the hemisphere that may be involved through international treaties or common conservation threats. Although birds are among the most well-known groups of organisms...
