This species occurred fairly regularly but 

 never in large numbers. It was seen most con- 

 sistently between October and February--peak 

 numbers were in December. Its distribution 

 appeared to be random (fig. 9). Birds were 

 seen from lat. 10° to 25° N. and from long. 148° 

 to 157° W. No density center was indicated. 



Owing to possible confusion in identification 

 between this species and the similar Kermadec 

 Petrel, Phoenix Petrel, and Tahiti Petrel, most 

 identifications were tentative. 



POBSP personnel have collected specimens 

 from comparable latitudes west of the study 

 area (Gould and King, 1967).
