Wedge-tailed Shearwater: 
(Puffinus pacificus) 
Wedge-tailed Shearwaters were seen in fairly low numbers throughout 
this leg of the cruise, although the numbers did begin to increase as we 
approached the Line Islands on the 10th and 11th (see table). The ^ark- 
phase birds were scarce the first two days (l on the 8 th, none on the 
9th) but began to increase as we traveled south of 11-03 N. Five dark 
phase birds were observed on the 10 th ( 29 % of total) and sixteen were 
seen on the 11th. (76% of total). The numbers of birds seen in flocks 
were low except for the 10th of November when h7% were observed in blocks. 
No directional trend could be established for these birds on any of the 
four days of observation. 
Christmas Island Shearwater: 
(Puffinus nativitatus) 
One Christmas Island Shearwater was observed with a small group of 
birds (1 Wedge-tail and 2 Black-wings) on the 11th of November at 06-U6 N; 
I 6 I-I 16 W. 
Juan Fernandez Petrel: 
( Pterodroma externa ) 
This species was very abundant for the first two days, then tne numbers 
decreased drastically (see table). Almost no birds of this species were 
seen south of 09-18 N. A fairly high percentage decreased as we traveled 
south. 
On the 8 th, most of the birds in flocks were in groups consisting 
entirely of Juan Fernandez Petrels. As we moved farther south, however, 
more were seen in mixed flocks of Sooty Terrs and Shearwater Petrels. No 
directional trend could be established for these birds. Most of them seem¬ 
ed to be milling about, searching and feeding. An additional 27 birds 
identified only as Pjrterodroma exte rna but probably Juan Fernandez were 
seen during the first leg of the cruise. 
White-necked Petrel: 
(Pterodroma externa cervicalis) 
Two birds of this species were observed on the 11th of November 
near Palmyra Island. 
Kermadec Petrel: 
(Pterodroma neglecta) 
Three light phase Kermadec Petrels were seen on the 8 th and 9th of 
November (see table). Two of these birds were in mixed feeding flocks and 
the other was a single bird. 
Dark-rumped Petrel: 
(Pterodroma phaeopygia) 
Three birds of this species were observed on the 8 th of November, fly¬ 
ing in a group at a position of 19-09 N: 1^8-30 W. 
Mottled Petrel: 
(Pterodroma inexpe ctata ) • _ ^ 
One Mottled Petrel was sighted traveling south on the 11th of November 
at 07-00N; iol-Ul W. 
Phoenix Island Petrel: 
(Pterodroma alba) . 
No Phoenix Island Petrels were seen until the third day, as we traveled 
south of 11-00 N, (see table). Two positive Phoenix Island Petrels and 1 
Island or Tahitidn Petrel were seen on the 10th of November. One of tnese
