Female McKay's Bunting on St. Matthew Island.
Alaska provides breeding habitat for more than 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 developed the Alaska Landbird Monitoring Survey (ALMS) to monitor breeding populations of landbirds in the vast off-road areas of Alaska and to complement data collected from the roadside BBS.
The primary objective of ALMS is to monitor population trends of northern populations of landbirds using replicated point-count surveys in off-road areas. This approach complements data collected by the roadside BBS.
In addition to trend monitoring, similar surveys conducted for inventories or other purposes can be incorporated into analyses of distribution, habitat use, and population size (see Figure 1). Most ALMS samples consist of a mini-grid of 12–25 points arranged within a randomly shifted 10 km × 10 km grid across continental Alaska.
- Surveys for population trends are conducted biennially, with half of the samples surveyed in alternating years.
- Samples are stratified by accessibility and cost, and the initial stratum includes areas accessible by foot, vehicle, boat, or fixed-winged aircraft.
- The initial allocation of samples is concentrated in the Northwestern Interior Forest and Northern Pacific Rainforest Bird Conservation Regions, where landbird populations are most diverse and abundant.
- Additional samples have been allocated to Arctic and Western Alaska, with surveys in the remote Aleutian and Bering Sea islands conducted by Alaska Maritime National Wildlife Refuge biologists as logistics allow.
The updated ALMS protocol (Handel et al. 2021) specifies 10-minute point counts replicated once per breeding season, with bird detections recorded in time and distance intervals to estimate detection probability.
- Associated habitat data are collected during the first summer of point counts, with subsequent habitat surveys repeated every 10 years or following a major disturbance.
- Long-term monitoring will enable analysis of change in bird populations in relation to fire, disease and insect damage, resource development, climate change, and other landscape-level disturbances.
ALMS has received broad support from nine state, federal, and non-governmental agencies, which signed a Memorandum of Understanding in 2005 supporting the program.
For more information on participating in ALMS or adding sampling sites, please refer to the additional information on this site or contact the Program Coordinator.

Beak Deformities in Landbirds
Over the past 26 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. If...

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.
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.
