PACIFIC SEABIRD GROUP
Dedicated to the Study and Conservation of Pacific Seabirds and Their Environment
The Pacific Seabird Group (PSG) is a society of professional seabird researchers and managers dedicated to the study
and conservation of seabirds. PSG was formed in 1972 out of a need for increased communication among academic and
government seabird researchers. The principal goals of PSG are to (1) increase the quality and quantity of seabird research
through facilitating exchange of information; (2) identify and assess the importance of threats to seabird populations;
and (3) provide government agencies and others with expert advice on managing populations of seabirds. PSG is headed
by an Executive Council composed of members volunteering their time. Members include biologists, wildlife managers,
students, and conservationists from the United States, Mexico, Canada, Japan and 12 other countries. PSG annual meetings
and publications provide forums where members can share their findings on all research topics relating to Pacific seabirds
and discuss local and large scale conservation issues. Abstracts for meetings are published on our website. PSG publishes
the on-line bulletin Pacific Seabirds (formerly the PSG Bulletin; www.pacificseabirdgroup.org) and the journal Marine
Ornithology (www.marineornithology.org). Other publications include symposium volumes and technical reports; these
are listed near the back of this issue. PSG is a member of the Ornithological Council and the American Bird Conservancy.
Annual dues for membership are US$50 (individual); US$35 (student, undergraduate and graduate); and US$1,500 (Life
Membership, payable in five US$300 installments). Two-year memberships are also available for individuals for US$90
and for sudents for US$55. Dues are payable on our website or by check to the to the Treasurer; see the PSG website or the

Pacific Seabirds
This on-line bulletin reports on the work and committee activities of the Pacific Seabird Group, conservation news, and
other items of importance to conservation of seabirds in the Pacific Ocean. The bulletin is published twice-yearly on the
PSG website and reports membership news and archives PSG activities. This issue provides current and recent seabird work
to PSG members for 2019. Back issues of Pacific Seabirds are posted on the group’s website.

Marine Ornithology
Marine Ornithology is published by the Pacific Seabird Group on behalf of a consortium of seabird groups: African, Aus-
tralasian, Dutch, Japanese, Pacific, and UK. The journal is published two times a year and publishes contributed papers,
forum articles, and book, website and software reviews, on all aspects of marine ornithology worldwide. For details on
