Surveillance of North America's wild ducks and shorebirds for 26 and 16 years, respectively, revealed differences in the prevalence of orthomyxoviruses between these hosts. Shorebirds had a high frequency of influenza A virus isolation during their northern migration, while wild ducks had high virus isolation frequencies during their southern migration.(More)
Migratory waterfowl of the world are the natural reservoirs of influenza viruses of all known subtypes. However, it is unknown whether these waterfowl perpetuate highly pathogenic (HP) H5 and H7 avian influenza viruses. Here we report influenza virus surveillance from 2001 to 2006 in wild ducks in Alberta, Canada, and in shorebirds and gulls at Delaware Bay(More)
Serologic testing to detect antibodies to avian influenza (AI) virus has been an underused tool for the study of these viruses in wild bird populations, which traditionally has relied on virus isolation and reverse transcriptase-polymerase chain reaction (RT-PCR). In a preliminary study, a recently developed commercial blocking enzyme-linked immunosorbent(More)
The behavioural rhythms of organisms are thought to be under strong selection, influenced by the rhythmicity of the environment. Such behavioural rhythms are well studied in isolated individuals under laboratory conditions, but free-living individuals have to temporally synchronize their activities with those of others, including potential mates,(More)
For management, it is important to understand the factors that affect foraging efficiency of birds during migration, especially in the face of severe storms and sea-level rise. An experiment was conducted whereby a beach used extensively by migrant shorebirds and people was open and experimentally closed to human activity to examine factors affecting(More)
Hurricane Sandy resulted in massive destruction of many coastal ecological and human communities in the Northeastern United States in 2012. Beach-nesting and migrating birds are vulnerable to loss of essential habitat as a result of storms. In this paper we report the perceptions of beach users about avian use of the beaches, conservation measures to(More)
Stakeholder contributions to conservation projects often occur during the problem formulation stage, yet the role of stakeholders throughout the process is seldom considered. We examine the diversity of state and federal agencies, conservation organizations, other non-governmental organizations, environmental justice communities, consultants, industry, and(More)
