Festivals Celebrating Birds in Alaska
Here are a few festivals celebrating birds around the state of Alaska.
Aleutian Islands Ecosystem Recovery Studies
The Aleutian archipelago is a 2,000 km long chain of volcanically-derived treeless islands stretching from Unimak Island in the east to the Commander Islands in the west. These volcanic islands support a wide range of species including large numbers of seabirds and marine mammal species, some of which are threatened and endangered, leading to a high level of federal management concern.
Bird Migration and Influenza
The movement and transmission of avian influenza viruses in wild birds may differ by the migratory nature of each host species.
Terrestrial Ecosystems
The USGS conducts research on trust Department of Interior migratory bird and mammal species and their habitats to inform agencies such as the US Fish and Wildlife Service, Bureau of Land Management and National Park Service in their natural resource management decisions.
Beak Deformities in Landbirds
Over the past 20 years, Alaskans have witnessed a startling increase of beak deformities among Black-capped Chickadees and other species of resident birds. This disease, called avian keratin disorder (AKD), is characterized by debilitating beak overgrowth and other abnormalities of keratinized tissues. Affected birds have difficulty feeding and preening, and may suffer high rates of mortality.
Dabbling and Diving Duck Research
Dabbling and diving ducks, such as mallards, pintails and scaup, are widespread species throughout North America. Additionally, their migratory flyways pass through Asia and North America overlap in Alaska. Population trends of these species are closely tracked through aerial surveys by management agencies. Results from these and other surveys are then used to formulate management actions to...
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 just recently, very little was known about sea ducks in Alaska.
