    Looking back on a year of Puget Sound surprises: rare birds, gray whales, water

    The year 2025 has been fairly mystifying to experts who make their living studying natural systems in the Puget Sound region.

    Unusual observations this year include record-low dissolved oxygen levels, unexpected gray whale visitations, and the sudden arrival of an astounding number of short-tailed shearwaters — a seabird almost never seen in Puget Sound.

    Migration
    false - false - true - Seen along British Columbia, U.S. west coast, and in central Pacific during southward migration in late northern summer through winter (National Geographic Society 1983, Cogswell 1977, Pratt et al. 1987). Some nonbreeders remain off California during northern winter (National Geographic Society 1983).

    false
    Food Comments
    Eats fishes taken from surface or by diving (Terres 1980).
    Reproduction Comments
    Egg laying occurs in November. Clutch size is 1. Incubation lasts 52-55 days. Tends to retain same mate in successive years. See Wooler et al. (1990). Some islands have colonies of several hundred thousand pairs (Austin et al. 1994).
    Ecology Comments
    Nonbreeding: may form flocks of at least 10,000s. <br><br>Despite strong philopatry, colony founding and recovery from population reductions evidently occur via immigration of a large number of individuals (Austin et al. 1994).

    Global Range
    Breeds on islands off coast (and locally along mainland coast) of southern Australia, with largest numbers around Tasmania and islands of the Bass Strait (see map in Austin et al. 1994). Ranges at sea in southern Australian and New Zealand waters, and north through Pacific Ocean to Bering and Chukchi seas (some to Beaufort Sea), south along west coast of North America to Baja California (Los Coronados Islands).
