for the grid are just slightly higher than that recorded during the May cruise. 
A total of 9 streamered birds were recorded in the grid area at distances 
up to hO miles from Howland. Peak days were noted on 1$ July N of Howland 
and on 20 and 21 July between Howland-and Baker Islands* 
Brown Booby (2U + 1 nocturnal) 
As with the previous species higher numbers recorded during the present 
cruise can be attributed to increased cruise activity near Howland. One 
third of the sightings occurred on 20 July on a short cruise south of Howland* 
Two blue-streamered birds were observed south of Howland at U and 5 miles 
distant* 
« 
Red-footed Booby (U7* 1 nocturnal) 
Most sightings occurred near the two central islands. This species is 
presently in the midst of a breeding cycle on Howland# One blue-streamered 
bird was observed between Howland and Baker. 
Great Frigatebird (10) 
Lesser Frigatebird (112) 
frigatebird species (556 6 nocturnal) 
Frigatebirds were commonly associated with most large feeding flocks 
throughout the grid area* and were especially abundant near Baker Island* 
Since the vast majority of breeding frigatebirds on Howland are Lessors* 
the majority of unidentified birds in the grid are logically of this species* 
A total of nine Lesser Frigatebirds were collected. The numbers of breeding 
birds on Howland have increased approximately three-fold since May 1966.
