Seabird associations in Pacific equatorial waters
Seabirds were counted along the same cruise tracks in the eastern tropical Pacific (10°øN‐10°øS and 140°ø‐90°øW) each spring and autumn for 8 years, 1984–1991. During spring, three species groups were apparent among eight species seen in five or more years: (1) Leach's Storm‐petrel Oceanodroma...
