Leach's Storm Petrel Oceanodroma leucorhoa .527 .710 .094 .011 .292 .274 .000 .023 .038 Linear density per section A southward moving population was present during the survey of the northern third of the Grid, but had evidently passed through the Grid area by the end of the survey. Ten birds were found associated with a pair of Killer Whales on 17 November. The birds were evidently feeding on the remains of some unidentified prey that the whales had taken. Only one dark-rumped bird was noted during the survey. With greater than 95 percent certainty all Storm Petrels sighted were Leach's. Red-billed Tropicbird Phaethon aethereus Tropicbird sp. Two Red-bills (1 adult, 1?) were seen in Section V on the 20th. A poorly seen bird, thought to have been a Red-tail, was seen in the south- west division on the 22nd. Pintail Anas acuta The single sighting was of a flock of 32 birds flying south in Section S on the 16th. Oldsquaw Clangula hyemalis A single female circled the ship on 21 November in Section Z. This constitutes the first sight record for the Grid area. Black Turnstone Arenaria melanocephala A single calling bird investigated the ship briefly on the 16th in the northeast subsection (T).
