Pterodroma hypoleuca 
Bonin Island Petrels were seen In low numbers north of 20° with 
abundance increasing as the track went north. One Black-Winged Petrel 
was seen just west of Kauai. 
Bulwer Petrel 
Two were identified in the southeastern area of the track and one 
was seen west of Kauai. 
Wedee-tailed Shearwater 
Low numbers were* recorded in scattered areas throughout one crdis^ 
(see Map 7). Most of the sightings were of birds in mixed flocks, ana 
all were light phase. 
Small Suomi Petrels

Leach's Storm PetreLs were seen in low numbers throughout the 
cruise. Additional birds identified only as White-rumped Storm Petrel 
were also seen, but not identified. To the north of Klhoa, 17 small 
Storm Petrels with dark rumps were also seen. To both rOBSr observers 
these appeared to have been the same size as Leach's Storm. Petrels;^in 
one instance a small Dark-rumped Storm Petrel was seen vitn a macn s 
Petrel. Both appeared to have been the same size, in anotner instance 
a group of seven Dark-rumped Storm Petrels was seen sitting on tne vaser¬ 
ene was decidedly larger than the otiters and must have oeen aitner - 
Bulwer or Sooty Storm Petrel. Thus the question arises as to what the 
smaller Dark-rumped Storm Petrels were. Tne writer feels tnat fcnej we^e 
leach's, but the dark phase has never been recorded in tne Hawaiian 
waters. Tne question also arises as to Why they were found only near 
Kinoa. Perhaps we either misjudged the size 01 tne storm petre^o, or 
possibly there is a dark-rumped race of Leach's Storm Petrel u.o_r^ *«ic^- 
as a nesting area. Tne latter suggestion would seem highly uni—kely 
no form of leach's Petrel has been recorded nesting in the Ha^aiic^is, 
but the conditions of the sightings described above also imply thau we 
were pretty sure that what we were seeing were small Storm Petrels. 
In addition to the Storm Petrels described above there were also a 
few sightings of White-rumped Storm Petrels whicn were recorded as being 
either Wilson's or Harcourt's Petrels. Judging by the flight the writer 
feels that these were Harcourt's; the chances of their being tnis species 
are more likely than of their being Leach's. 
Red-tailed Tropicbird 
Surprisingly few were recorded on the cruise; all were seen on the 
eastern two-thirds of the cruise track. 
White-tailed Tropicbird 
All sightings were within 75 miles of the main Hawaiian
