Phalarope: Both the Northern Phalarope (Lobipes lobatus) and the Red Phalarope (Phalaropus fulicarius) were thought to be present, but it was impossible to distinguish between them. Both species, especially the latter, have occurred in the Central Pacific. Jaeger: Two Pomarine Jaegers (Stercorarius pomarinus) and one Parasitic Jaeger (Stercorarius parasiticus) were identified. Only the former is found in the Central Pacific. Gull: This is the most abundant group within the grid area and as such almost completely dominates the avifauna. All, with the exception of the Black-legged Kittiwakes, are avid ship followers and are most abundant in the areas where ships are maneuvering. Western Gull (Larus occidentalis) - A total of 10 adults and probably several more immatures was recorded following the ship. Glaucous-winged Gull (Larus glaucescens) - Two different immature birds were recorded. Herring Gull (Larus argentatus) - At least 19 adults were recorded although many immatures were probably also present. California Gull (Larus californicus) - A minimum of 16 individuals was recorded although it was impossible to keep track of single birds following the ship. All of these were adult birds, but it is assumed that many of the immature birds following the ship were also of this species.
