Breeding & Non-breeding data
BREEDING
• Central-place foragers (esp. when chicks are young)
• Lasts 6-12 months per year
NON-BREEDING
• Less tied to breeding sites
• Variety of types of non-breeding (Non-breeding season, juveniles, non-breeders)
• All year
• Fewer non-breeding data

NON-BREEDING:
Post-breeding distribution of Laysan (red) & Black-footed (yellow) Albatross
tracked from Hawaii(Scott Shaffer, TOPP, In Press)
Summary of tracking data
SOUTH PACIFIC
• Waved Albatross
• Black-browed Albatross (Chile) esp. non-breeding
• Non-breeders from New Zealand(Chatham, Salvin’s and Buller’s above 40°S)
• Concentrated in EEZs but migrate across high seas
NORTH PACIFIC• Important for Black-footed Albatross
esp. non-breeders (also Laysan Albatross)
• Extensive use of high seas areas (mostly above 20°N)
RFMO Seabird Assessments:
IATTC Seabird Resolution ‘05 Seabird Assessment
ICCAT Seabird Resolution ‘02 Seabird Assessment
IOTC Seabird Resolution ‘05 Seabird Assessment
WCPFC Seabird Resolution ‘05 Mortality estimates
CCSBT Seabird Resolution ‘97 ?
• What next?
• Coordination with other RFMOs?
A few questions…
