Kermadec Petrel 
One bird, a dark phase, was seen on 20 April. This is the first 
spring (March-June) sighting of this species in the area. 
Dark-rumped Petrel 
Three were seen in April, all under good light conditions. Two were 
in the southeast corner and the third was 200 miles north of the high 
Hawaiian Islands. 
Juan Fernandez Petrel 
All of the 21 birds seen this month were in the southeastern corner. 
Most had splotchy plumage, indicating the beginning of molt in this species. 
Humbers seen were consistent with the low totals noted for Jan-April in 
both 1964 and 1965 . 
Herald’s Petrel 
One bird observed at close range but in poor light on 19 April may 
have been this species. 
Cook’s Petrel 
One was seen on 24 April toward the southeastern corner of the area. 
A substantial increase over the January-April low is expected in May. 
Bonin Island Petrel 
One bird was seen in good light on 28 April, 25*0 miles north of the 
high Hawaiian Islands. This species occurs only rarely in the BCF area. 
The possibility of confusion with the similar Cook’s Petrel make positive 
identification difficult under any other than optimum observation conditions.
