Black-capped Chickadee with a long down-curved elongated top beak. Avian keratin disorder (AKD) is a disease 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.

Alaska Raptor Group
Thirty-one raptor species, including 18 species of diurnal raptors (Orders Accipitriformes and Falconiformes) and 13 species of owls (Order Strigiformes), have been documented in Alaska, 23 of which are known to breed within the state.

Boreal Partners in Flight
WELCOME to the Alaska Landbird Resource Information System, the official web site for Boreal Partners in Flight! Thanks for taking the time to learn more about the Boreal Partners in Flight program and our efforts to understand and conserve northern populations of landbirds.
About Boreal Partners in Flight
Boreal Partners in Flight is a coalition of individuals who are working together to help conserve bird populations throughout boreal regions of North America. Boreal Partners in Flight is the official Alaska state working group of the international Partners in Flight program. We also have many members from Canada because we share many of the same species, habitats, and problems. The international...
Monitoring and Research Boreal Partners in Flight Projects
Boreal Partners in Flight has five major regional projects designed to monitor broad-scale trends in populations of landbirds. There are also many projects throughout Alaska that address specific research questions or local monitoring needs.
Alaska Landbird Monitoring Survey
Alaska provides breeding habitat for >140 regularly occurring species of landbirds, half of which breed predominantly north of the U.S.–Canada border. The road-based North American Breeding Bird Survey (BBS) provides some data on population trends in Alaska, but most northern species are inadequately monitored by that continental program because of a paucity of roads. Boreal Partners in Flight...
Conservation of Landbirds in Alaska
Alaska lies at the convergence of four major global migration flyways and encompasses a diverse array of important landbird habitats. Temperate rainforests tower along the southern coast, boreal forests span the vast interior, and low-lying tundra blankets the continent’s northern and western fringes.
Bird Conservation Areas
Five Bird Conservation Regions (BCRs) were designated in Alaska as part of the North American Bird Conservation Initiative in order provide a framework that would facilitate coordinated conservation and evaluations of major bird initiatives.
Festivals Celebrating Birds in Alaska
Here are a few festivals celebrating birds around the state of Alaska.
Background of Beak Deformity Research
Large numbers of Black-capped Chickadees with abnormal beaks were reported in south-central Alaska in the late 1990s. More recently, similar beak deformities have appeared in other species throughout the state. At least 30 Alaskan bird species are affected and the geographic extent of the problem appears to be growing. In addition to Alaskan observations, we have received increasing numbers of...
