White-necked Petrel 
One bird was seen at the southern end of the area on February 11.

Juan Fernandez Petrel 
One bird was seen at the southeastern corner of the area on 20 
February. In addition, two birds which were either this or the similar 
Lark-rumped Petrel were seen in the south on 12 February. Their very 
dark mantles made a distinction difficult, although the latter species 
is the more probable of the two. 
Leach’s Petrel 
Numbers of this species remained virtually unchanged; 83 were seen 
in February compared with 88 in January. Greatest numbers were concentrated 
toward the southern end of the area. None were seen in the area 200 miles 
south of Oahu where 37 were seen in one day in January. Few birds were 
seen along the two outermost legs of the grid. 
Red-tailed Tropicbird 
Only three birds were seen in February, the lowest monthly total 
for the area. Presumably, the winter decline in numbers reaches its 
turning point in February and numbers will increase in March.

White-tailed Tropicbird 
The ten birds seen in February were scattered throughout the area. 
No change in numbers was recorded between this and last month* 
Blue-faced Booby 
, o 
All four were seen south of lh N. The bird seen on 10 February 
appeared to be an adult; the other three were immatures. This is the 
first time an adult bird has appeared in the area.
