Breeding Black-footed albatross (<i>Phoebastria nigripes</i>) and Laysan albatross (<i>Phoebastria immutabilis</i>) nesting in Tern Island (Northwest Hawaiian Islands) and tracked during the 1998 breeding season (January - June) performed foraging trips to continental shelves off North America. Black-footed albatross made long trips to the west coast of North America (British Columbia to California). Laysan albatross traveled primarily to the north of the Hawaiian Islands, and reached the waters of the Aleutian Islands and the Gulf of Alaska. These albatross species mixed short and long trips during the chick-rearing period (February - June), but engaged in short foraging trips during the brooding period (within 18 days after chick hatched, January - February). Marine Biology Telemetry Tagged animal albatross satellite tracking North Pacific Ocean Hawaii Radio transmitters Animal movements N/A These albatross were tracked using PTT-100 Argos transmitters (Microwave Telemetry, Columbia, MD) operating at a 90-second repetition rate and programmed to operate on a 8:24 h ON:OFF duty cycle. Transmitter bench-tests before deployment revealed that the Argos location quality classes (lcs) had the following median position errors, expressed in kilometers: lc B (24.23), lc A (2.95), lc 0 (5.65), lc 1 (1.53), lc 2 (0.73), and lc 3 (0.44).<br><br> The low-quality class B locations were discarded because they misrepresented the telemetry tracks. Thus, this dataset includes 3505 high-quality locations (lc classes A or better) with median positional errors <6 km.

An understanding on the foraging biology of North Pacific albatrosses has important implications for assessing their bycatch risk in commercial fisheries.<br><br> We thank C. Alexander, L.
