Several times today large petrels were seen that appeared mottled 
on the back as if molting. Both White necked and Dark-runped have been 
seen in this state. Some even had secondaries missing. Perhaps study 
skins will dispel our doubts. 
At 1140 feeding flock No. 2 appeared - 30 Booties, 2 wedgetails, 
3 Harcourts -most unusual - 4 shearwater unidentified and 1 white- 
necked petrel. At 1212 75+ 10 Sooty Terns were seen circling and feeding. 
No Shearwater/petrels were seen by me after careful scruting although 
watch held contrary opinion. Watch was as stubborn as I. At 1555 a 
non-feeding flock of shearwaters and petrels passed. Two light and 
one dark Wedgetails, two molting Dark-rumped Petrels, two unidentified

Shearwater/petrels and a brown upper and white under petrel-size of a 
Newell's although chunkies - between Bonins and Dark-ruraped size - 
closer to Bonins. Upper parts uniformly dark brown. This same species 
seen again at 1640 briefly at close range. It had dark 3 pots around

Masked Booby seen three times today, over hour apart each time# 
A white-necked Petrel Sundell saw at 1300 apparently miscalulated 
proximo ty to ship and twisted and turned Just in front of it, finally 
soaring to 50 feet circling ship. At 1540 we turned North after finishing 
a long hydro station at 10° N. At 1635 and again just 
at sundown had good
