Wild lesser scaup from the Chesapeake Bay, captured and implanted with satellite transmitters for a separate ecology study, were opportunistically sampled for avian influenza. These data detail the virological sampling results, obtained post release, which include a single positive for clade 2.3.4.4 H5N1 virus of the A/goose/Guangdong/1/1996 (Gs/GD) H5N1 lineage of highly pathogenic IAV. These data also include the movements of the infected bird from release until death as well as four conspecifics marked and released concurrent with the HPAI positive bird. These data support a paired publication.

Bycatch is the incidental mortality or injury in fisheries operations. Many seabirds are proficient swimmers, some diving many tens of meters in pursuit of fish (Brierley and Fernandes 2001, Regular et al. 2013). Diving seabirds swim into, become entangled and drown in fine nylon mesh gill nets due to their lack of visibility. This problem is often exacerbated at dawn and dusk when birds are most actively feeding and when nets are hardest to see (Melvin et al. 1999). The North American Waterbird Conservation Plan identifies fisheries bycatch as a serious threat to at least 17 species of seabirds in the Mid-Atlantic/New England/Maritimes, and Southeastern regions, an area including all U.S. Atlantic waters (Kushlan...

New lightweight solar-powered global positioning system (GPS) transmitters have the potential to revolutionize our understanding of animal movement and behavior. With a predicted lifespan of 3-5 years, and the capacity to record frequent locations to within 3 m, these tags provide continuous and precise data that allow for sophisticated analyses that require time-invariant sampling and relocations with low error. Examples of these next-generation techniques include analyses that incorporate barriers to movement, autocorrelation of data, and mechanistic approaches to modeling (Cleasby et al. 2015) that include metrics such as weather, shifting resource availability, and habitat. Such models offer resource managers...
