Except for Nesofregatta.m ost records of Storm Petrels were recorded 
as Storm Petrel Sp?, or White-ramped Storm Petrel, Leach 1 s Storm Petrel 
is undoubtably the predominant species, except near the Hawaiian Chain where 
Harcourfs Storm Petrel has been reported as breeding. Migrating Wilson*s 
Petrels were observed and collected in the Southern Grid. Almost certainly 
at least one more species occurs in the study area, but no further species 
have been collected as yet. 
White-tailed Tropicbird A-9 B=8 C®l+8 D^IO 
( Phaethon lepturus ) Number Collected s l 
Concentrations of this species were observed north of Samoa where 
as many as 30 were observed in flocks and in some cases were the main 
flocking species. Special attention should be given to identification 
of this species as it is surprisingly easy to confuse with Fairy Terns 
at a distance. 
Red-tailed Tropicbird A*!^ 3*3 09 D-6 
( Phaethon rubricauda ) 
Pelagic distribution was fairly uniform over all regions with a 
slight concentration in the northern areas. While inter-island banding 
returns show little breeding movement, at-sea collections are indicating 
that the pelagic dispersion of this bird may be far wider than expected, 
and more collecting at-sea is warranted. 
Blue-faced Booby A*0 B*1 068 D=i 
(Sula dactylatra ) 
An adult just N.E. of Johnston Atoll probably is from the main Hawaiian 
population. An immature (dark head) was seen just below 5°N. This is 
probably a Howland bird. Grid observations indicated a marked outward 
dispersal of the maturing locals from Howland. 
Brown Booby A-9 B*Q 012 D»3 
( Sula leucogaster ) 
All observations are land-dependant. Records from off Gahu, Johnston 
Atoll, and the Phoenix Islands.
