    It is my understanding that the large ( no longer)  Alameda Naval Base
    (ANB) Elegant Tern nesting colony moved north to the islands on the
    Columbia River Inlet - Oregon  and Washington .
    This was due to the change in habitat on ANB.
    ANB would scrape the shore along the bay and man made channels on ANB
    producing nesting and roosting habitat.
    When ANB was de-commission all that so-call maintenance stopped.
    Least Terns now nest on the run ways.
    Federal wildlife biologist tracked the Elegant Terns to the Columbia River
    region of the Northwest.
    Once the birds were established on these islands ( I'm told ) they ran into
    conflict with commercial Salmon Fishing Fleet.
    The fishing industry has been claiming that the salmon numbers / fall catch
    is down due to Elegant Terns eating the annual smolt run out into the
    Pacific.
    There may have been a petition file to reduce the size ( shooting them ) of
    the  Elegant Tern Colonies.
    I'm not sure of  the status of that petition.
