New Zealand Shearwater (Puffinus bulleri) 3 Three sightings in the northwest portion of the grid represent the first record for this species in the grid. All were traveling north. Pink-footed Shearwater (Puffinus creotopus) 1 A single bird in the western half of the central section was the first grid recording for this species. Judging by non-grid observations, it was probably a migrant. Sooty Shearwater (Puffinus griseus) 31 Although most were identified as being either Sooty or Slender-billed Shearwater, none with good Slender-bill field marks were recorded. Also, judging from large non-grid collections, all were probably Sooties. The influx from previous surveys is accounted for by a northward migration from the breeding grounds in southern latitudes; virtually all of the observations were of single birds traveling north. It hardly need be said that because of this, north-south densities as calculated on table two are practically meaningless. But in view of non-grid observations, it is quite interesting that east-west densities within the grid were virtually even. As large concentrations were found off the channel islands and around Cortez Bank, one would expect that grid densities of northward bound birds would have been much higher in the eastern part of the grid. Additional surveys may explain this phenomenon. Herald's Petrel (Pterodroma heraldica) 1 The collection of this species constitutes the first reliable record for the grid. The field identification of one in January is the only other sighting for the grid. Leach's Storm Petrel (Oceanodroma leucorhoa) 125+ 7 Nocturnal Storm Petrel Species (Unidentified) 12 + 4 nocturnal Although not usually recorded to species, probably all of the storm petrels
