Sine© egg dates for Hawaii are thought to be Apr il-May and for the Galapagos 
race Jun e-July, it may be the case that the northern, fresh pi imaged birds 
are the Hawaiian race and tlie southern, heavily" molting birds are from tie 
Galapagos Islands.

Numbers of this species increased from three in April to 3 k in May. 
All of these were seen in the southern end of the grid area* All were 
undergoing heavy molt. I any had missing primary and secondary wing feathers 
and bird3 were flushed from tiie water by the approaching ship. This species 
was often seen in close company with molting Dsrk-ruKped Petrels, sometimes 
two or three of each species sitting together on the water. This species 
was found in the southern feeding flocks along with molting Bark-rump ed 
Petrols, dark phase Vedgetails and Sooty Terns. 
Bulwer’s Petrel

Oahu. Small flocks of up to nine individuals were seen, and a number of 
birds were seen in and around the edges of feeding flocks of Sooty Terns 
and Wedgetailed Shmiwaters, bub none was observed feeding. 
Hare Quit's Storm Petrel
