    Notes from the field: The Illusion of abundance

    Biologist and science writer Eric Wagner recently returned from a trip to observe pigeon guillemots on Protection Island. He wonders: How much do we really know about the health of seemingly abundant bird populations?

    Unsung seabirds could help track Puget Sound health

    Pigeon guillemots have attracted relatively little scientific attention compared to other seabirds in Puget Sound. That may be because their population is generally stable, but a group of citizen scientists is helping to put guillemots on the conservation radar. They hope the birds can be used as an indicator of Puget Sound health.

    Washington state aquatic reserves

    Eight aquatic reserves, managed by the Washington Department of Natural Resources, have been established to protect important ecosystems on state aquatic lands.

    In most reserves, area residents work with state, local and tribal officials and nonprofit groups to develop and carry out management plans, including scientific research.

    The aquatic reserves in the order they were established include: 

    • Maury Island 2004
    • Cypress Island  2007
    • Fidalgo Bay 2008
    • Cherry Point 2010
    • Protection Island 2010
    • Smith and Minor Islands 2010
    • Nisqually Reach 2011
    • Lake Kapowsin 2016

    Marine and terrestrial bird indicators for Puget Sound

    A December 2013 report identifies marine and terrestrial bird species for use as indicators within the Puget Sound Partnership's "Vital Signs" for ecosystem health.

    2012 Puget Sound Marine Waters Overview

    The Puget Sound Marine Waters 2012 Overview from the Puget Sound Ecosystem Monitoring Program synthesizes conditions measured in 2012 and has been expanded to include observations on seabirds that rely on marine waters. Read an excerpt below, or download the full report.

    Marine birds

    More than 70 bird species regularly utilize Puget Sound during some or all stages of their life histories, but only a portion of these are actively being investigated.

    Informal Taxonomy
    Animals, Vertebrates - Birds - Other Birds
    Formal Taxonomy
    Animalia - Craniata - Aves - Charadriiformes - Alcidae - Cepphus - Composed of two groups: COLUMBA of western North America and eastern Siberia and SNOWI of the Kuril Islands (AOU 1998). Constitutes a superspecies with C. GRYLLE and possibly C. CARBO of Asia (AOU 1998).
    Migration
    true - true - false - Generally sedentary; probably almost wholly resident at least as far north as British Columbia and Washington, also throughout Gulf of Alaska and Aleutians (Johnsgard 1987). Arrives in breeding sites in central California in early March (Nelson 1987).
    Non-migrant
    true
    Locally Migrant
    true
    Food Comments
    Diet mainly small fishes (e.g., blennies, sculpins, sand launce, smelt, etc.); generally inshore benthic species; also includes mollusks, crustaceans, and marine worms. Forages underwater. Off southern British Columbia, foraging birds occurred mainly in areas where water depth was 10-20 m (Clowater and Burger 1994).
    Reproduction Comments
    Breeding begins from mid-May in south to mid-June in north. Clutch size is 1 or (usually) 2. Incubation by both sexes, lasts 30-32 days. Young are tended by both adults, can fly at 29-39 days. Yearlings and most 2-yr-olds do not breed; first breeds generally at 3-4 years on Farallon Islands (Nelson 1991). Nests singly or in loose aggregation or small colony. Tends to retain same mate in successive years.
    Ecology Comments
    High (80%) annual adult survivorship (Nelson 1991).
