Kermadec Petrel A*Q B»3 C“*> 
Seven of the eight birds observed were single sightings* The re m a in ing 
bird was in a «nu> ll mixed flock of terns and shearwater-petrels* predominantly 
Wedge-tails* Only one individual was encountered last month* 
Dark-rumped Petrel A-6 B"0 C-l 
Approximately 10% of the birds were observed during a short period 
before sunset near Kauai* Large numbers of Newell's Shearwaters were also 
in evidence at this time. Although the number of Dark-rumps were few, it 
is possible that a small breeding colony exists on Kauai* 
Bonin Island Petrel A*12 B*69 036 
Included here are both the typical Bonin Island race and that which 
has been referred to as Cook* s or Black-winged Petrel* Only $0% of 
the birds observed could be identified as to race, but of these, 90% 
were the Black-winged type# These were also abundant last month and exceeded 
the Bonin Island type by 5-1# Birds of combined races were distributed 
/ * 
fairly evenly over the cruise area except for a pronounced scarcity along 
the main Hawaiian Islands# Numbers were slightly higher last month* 
Bulirer * 1 s Petrel A*660 062 
This species was largely confined to the Leewards# Large numbers 
(over 80^ of tbtal) were observed on 3 August between Nihoa and Necker 
I Islands. Most sightings were of single birds or pairs. On occasions when 
three or four birds were seen together, they normally did not form compact 
m 
\ groups. Birds seen near mixed feeding flocks of terns. Wedge-tails etc* 
- appeared to be there purely by accident and were never noted to Join actively
