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.
