identified as adults. I believe that the najority of birds found in .e •- 
Northern Grid this January were wandering immatures or sub-adult ^ir i* . 
These birds are not island based and are not heading in any particular direction, 
but were merely "drifting** until they mature and retiirn to the breeding islands.

BIRDS ANNOTATED BItHD LIST 
Black-footed Albatross 
(Diomedea ni};ripes) 
« 
Sub-adults followed the ship on three different days. On the 11tn of 
January three adults followed the ship indicating their feeding range jm 
their Leeward Hawaiian nesting grounds. 
Juan Fernandez Petrel 
(Pterodroma externa externa ) 
A decrease from lOU in December to 15 this month was expectea as uhis 
soecies-begins to breed in the Southern Hemisphere in late December. The 
birds, observed this month are most likely non-breeding sub-adults. 
Kermadec Petrel 
( Pterodroma neglecta ) 
Four light-phase Kermadecs were identified in the southern part of the 
grid. All were single sightings. The difficulty in separating these from 
Herald’s Petrel is realized and the p*ssibility of these birds being the latter 
species is acknowledged. 
Leach Storm Petrel 
( Oceanodroma leucorhoa ) 
Two individuals identified as White-rumped Storm Petrels were proo-ioly 
this species. 
i^ite-uailed Tropicbird 
( Phaethon lepturus ) 
Three individuals were observed on January 9. One was collected and proved 
to be a sub-adult. 
Red-tailed Tropicbird

Red-tails increased from 5 in December to Ih this month. A high of 7 on 
the 12th of January coincides with the least wind. One collected proved to 
oe a large sub-adult. An additional bird was observed sleeping on ti water 
during nocturnal observations.
