The section is only marginally "pelagic," a strong influence from 
Jarvis Blue-faced Boobies and Sooty Terns contributing to a large part of 
the total. Well over half the mileage is at pelaeic distance, mostly on 
the 29 th, when simultaneous observations were conducted on vessels 86 and 39* 
Sooty Shearwaters and Leach Storm Petrels were more abundant over this sec¬ 
tion than in any other section. Among the miscellaneous sightings were a 
Golden Plover, a possible New Zealand Shearwater, and a possible Red 
Phalarope. While Blue-faced Boobies were commonest close to Jarvis, sev¬ 
eral birds were seen around 150 miles from land. Jarvis and Malden must 
account for at least 90 percent of the Line Island Blue-faced Booby breed- . 
ing population. This area has the highest Blue-faced Booby linear density 
of ai 1 sections.
