New Zealand Shearwater. One bird was collected from a feeding flock May 23> 
and 5 others were identified in the area between Johnston Island and 
Oahu. 
Juan-Fernandez Petrel. Found in greatest numbers in the easternmost area of 
i 
the route, May 8—11, and found in fairly constant numbers oyer the rest 
of track. Eight were collected. Most were molting. 
"White-necked Petrel. Two were identified in the southern part of the trip, 
and 1 or 2 were collected. 
Kermadec Petrel. Two were seen on May 7 &nd least two were sighted in the 
Grid on May 17 after the storm. The latter pair were both dark-phase 
individuals. 
Phoenix Island Petrel. Two were recorded shortly before sunset on May 9. 
Bark-rumped Petrel. One bird was identified as this species just south of 
the island of Hawaii. Others may have been observed. 
Mottled Petrel. Three birds were recorded, all in the Grid. All were flying 
northwest. 
Pterodroma spp. Included in this grouping are Cook T s Petrel, Bonin Island 
Petrel and an unidentified species closely resembling both previous spe- 
♦ 
cies, but lacking the heavy black underwing borders. It resembled a 
small Juan Fernandez Petrel. All three types were headed predominately 
northwest as in April. This indicates that the Bonin Island Petrels are 
southern migrants rather than individuals from the Leeward Hawaiian chain, 
in company with other migrants from the same area. 
Bulwer’s Petrel. Found in moderate numbers around the high Hawaiian Islands 
and in low numbers elsewhere. This species appears to be nearing the 
end of its return to breeding areas. Five were collected.
