Red-footed Booby (31 t 2 nocturnal) 
Over 6l% (19) of the sightings were recorded in one large mixed feeding flock 
approximately Hi miles SE Howland on 15 August. Most other birds of this species 
were also recorded in mixed feeding flocks. 
Great Frigatebird (7) 
Lesser Frigatebird (15?) 
unidentified frigatebirds (362 i 3 nocturnal) 
Frigatebirds were invariably associated with Sooty Tern feeding flocks and 
practically all frigatebird sightings were in such flocks. Over kh% of frigatebirds 
were recorded on lU August between Howland and Baker. Great Frigatebirds comprised 
less than 5% of all identified birds, a figure closely comparable to the actual 
numbers of the two species presently breeding on Howland Island. The large numoef 
of birds unidentified to species resulted from scanty attention during observations 
of feeding flocks when search for blue-streamered Sooty Terns was connsidered more 
important. One Great Frigatebird and two Lesser Frigatebirds were collected during 
grid operations. 
Golden Plover (5) 
Ruddy Turnstone (3) 
Wandering Tattler (2) 
The expected increase of shorebirds with the advent of fall migration is now 
becoming apparent. Only three shorebirds were recorded during July. Increased 
numbers can be expected during the forthcoming months. One Wandering Tattler 
was collected during the present cruise. 
Sooty Tern (3303 + 181 nocturnal) 
This species was again dominant during every day of the cruise and accounted 
for 80.of total birds (diurnal and nocturnal). This was roughly 10^ lower
