were recorded and 13 epocimcms of three species were collected. 
A combination of rough seas and mechanical failures prevented use 
of the skiff for collecting purposes. It was run only on 20 Nov¬ 
ember for a period of 2)4 hours, but 92 % of the total birds coll¬ 
ected were taken during this short span. Attempts to enter mixed

feeding flocks with the ship in order to view streamered birds 
this month proved fruitless. Most flocks encountered were not 
feeding intensely and the birds usually scattered upon approach

of the ship. An estimate of the percentage of Sooty Terns which 
were glassed throughout the grid period is difficult to make, but 
twenty—five percent does not seem improbable*.*^ No streamered terns 
were recorded. Although no terns are breeding on Howland at this 
time, considerable numbers are still present over the island. A 
flock estimated at 3,000 birds which was carefully scanned as they 
hovered over the beach contained no streamered birds. Apparently 
birds which formed the breeding colony during July and August 
which were heavily streamered have already moved out of the grid 
area. The Baker Island area utilized by Howland based birds since 
last spring is still attracting large numbers of terns, boobies 
and frigates, but the lack of marked birds leaves their origin in 
doubt. However, the sighting of most large, mixed feeding flocks 
within 20 miles distance of the islands indicates that grid birds 
might be Howland based. 
Nocturnal observations were ordinarily maintained from sunset 
to sunrise. A total of 512 miles and 56 hours were completed in
