    Waterbird Conservation Council
• Waterbird Conservation Council is the steering body for
    the Waterbird Conservation for the Americas initiative
•   Scope is seabirds and other aquatic birds in the Western
    Hemisphere; current membership drawn from nations
    throughout the Americas as well as initiatives such as
    BirdLife International, WHSRN, CMS and Ramsar.
•   Key outcomes of January 2007 meeting:
     –Intensified activities related to seabird conservation, and
     –Creation of a task force to develop a strategy for
     Americas-wide conservation of waterbirds

   „ Procellariidae (petrels, shearwaters, fulmars)
   „ Hydrobatidae (storm-petrels)                   Heiko Bargmann

   „ Phaethontidae (tropicbirds)
   „ Sulidae (boobies and gannets)
   „ Fregatidae (frigatebirds)
   „ Alcidae (auklets, murres, puffins)
   „ Laridae (terns/noddies)
        Global Conservation Status
„ Many are in decline and threatened with extinction

„ Diomedeidae, Procellariidae, and
  Hydrobatidae make-up 45% of
  global seabird species and
  74% of seabird species on IUCN Red List

„ NAWCP Assessments -
  100% “highly imperiled” and
  > 80% of both “highly imperiled
  AND “high concern” species fall
  within these families

                Overview of Threats
● impacts of non-native species on breeding grounds
    ●   predation
    ●   competition
    ●   habitat alteration/loss
    ●   disturbance
● fisheries interactions
    ● competition for prey
    ● incidental capture
● pollution (chronic and acute)                         Peter Ryan


    ● oil
    ● biomagnification of contaminants in food web
● plastic debris
    ● ingestion
    ● entanglement
● global climate change

     Science: Distribution and
           Abundance
●   ocean is not homogeneous
●   seasonal usage
●   foraging areas
●   linkage with climatic-oceanographic conditions
●   migratory routes                              Cordell Bank

                 Science:
             Impact of Fisheries
• nature of interactions
      • direct (bycatch; food subsidies)
      • indirect (prey depletion, availability)
• type and location
• population-level impact?                        Spatio-temporal
                                                      overlap

                                                     Fisheries
                                                    activity and
                                                      location
          Science: What’s Needed
• international national coordination of at-sea
  monitoring
• continent-wide seabird monitoring database
• monitoring programs to improve understanding
  of seabird population dynamics and trends
                                     Photo by Peter LaTourrette
• assess the risk of seabird
  interactions in particular
  fisheries
• education and promotion
  designed to increase
  awareness and to stimulate
  solutions
      Policy: Bycatch & Other Threats
„ Variety of Measures
  Available
„ Authorities, Means
  ‟   Migratory Bird Treaties
  ‟   Endangered Species Laws
                                    Short-Tailed Albatross by Yuri Artkuhin
  ‟   Fisheries Management Laws
  ‟   Environmental Statues
  ‟   Protected Areas Legislation
  ‟   International Instruments
        Policy: International
            Instruments
• 1990 UN global driftnet ban and 1995 FAO Code of
  Conduct

• 1999 FAO International Plan of Action – Seabirds
  • National Plans of Action: Assess, mitigate, and plan future
    research
     • Seven nations (and Taiwan) have NPOAs
         • Implementation varies
         • FAO and BLI will soon assist in the
          development of best practices
          guidelines

• 2004 Agreement on the Conservation
  of Albatrosses and Petrels

• Ongoing action within the RFMOs
        Policy: What’s Needed
• Collaborate and coordinate efforts
  internationally, within an overall seabird
  conservation framework
• Address seabird needs and threats through
  education, capacity-building, and partnership as
  well as regulatory or intergovernmental
  mechanisms
• Establish an alliance which brings together the
  organizations and instruments in a holistic,
  integrated approach.
                   Thank You
