Alaska Maritime NWR Seabird Monitoring
Project name:
Alaska Maritime NWR Seabird Monitoring

Project goal:
Monitor marine bird demographics and diets

Project keywords:

Overall project description:

Status: Active

Year started: 1975
Year ended:

Season(s) and frequency:

Geographic area covered:
Annual Sites: Chukchi Sea (C. Lisburne), Bering Sea (Bluff, Pribilofs), Aleutian Islands (Aiktak, Kasatochi, Buldir), Alaska Peninsula (Semidis), N. Gulf of Alaska (Barrens), E. Gulf of Alaska (St. Lazaria).

Important bird areas:
Pending Designation of up to 10

National parks and other protected areas:
Alaska Maritime National Wildlife Refuge

Type of habitats:
Sea cliffs, offshore islands and stacks, coastal tundra

Primary species covered:
Seabirds: Northern Fulmar, Red-faced Cormorant, Pelagic Cormorant, Fork-tailed Storm Petrel, Leach's Storm-petrel, Glaucous-winged Gull, Black-legged Kittiwake, Red-legged Kittiwake, Pigeon Guillemot, Common Murre, Thick-billed Murre, Crested Auklet, Least Auklet, Whiskered Auklet, Tufted Puffin, Horned Puffin

Methods with details of protocol and comments:
Ground counts of nests, nesting burrows, or individual birds on generally on index plots at colonies where samples of nests also are monitored for reproductive success, timing of nesting events, and other parameters. Adult survival estimated from samples of marked birds (kittiwakes and auklets only). Diets tracked by collecting regurgitations, observing fish brought to young, or collecting birds.

Sample design:
Variable - usually dependent on accessibility

Data (format and access):
Population trend data submitted to Pacific Seabird Monitoring Database, Colony-wide population estimates stored in Beringian Seabird Colony Catalog

Sample size:
For sample counts, 1000-2000 birds daily for 7 days, for nest counts

Results (format and publication/availability):
Annual Report of results on web

Trends and time series availability:
From mid-1970s to present at some sites, at least 10 years at most sites.

Relevant publications:
Data used in various publications

Funding source:
U.S. Fish and Wildlife Service

Lead Institution: U.S. Fish and Wildlife Service

Database custodian: U.S. Fish and Wildlife Service

Partner Institution(s):

Brief description of the application of the information derived from the monitoring effort:
General monitoring of migratory bird population trends to set management priorities. Provides indications of general marine ecosystem health and provides data from which hypotheses about changes in the marine ecosystem may be tested.

Main user of monitoring information:
U.S. Fish and Wildlife Service, and Ecosystem Researchers

People involved in monitoring:

Has any of the resulting monitoring information been used for a state of the environment assessment?
Used to evaluate IUCN threat categories and for North American Bird Conservation Plans. Also used to evaluate changes in marine food webs by scientists interested in global climate change, shifts in carrying capacity (for commercial fish and marine mammals).
