On one of the flocks that I saw today the petrels were flying very high, 
many of them above the Sooty Terns. At this heighth their flight is 
not typical of petrel or shearwater flight. The birds are also 
difficult to identify except for size differences unless you are close 
enough to distinguish their characteristics. The Cook's Petrels are 
also flying different when low to the calm water, they appear to spread 
their wings out farther and sty more level with the water. Juan 
I 
Fernandez Petrel also fly more like a Wedgetail when the water is calm. 
October 12 - -The sea was calm and the sky was cloudy this morning clear- 
ing this afternoon. This morning Juan Fernandez Petrel and Cook's 
Petrels were mainly seen. The Sooty Shearwaters were still heading 
south. Early this morning Warren saw an adult Brown Booby. Later 
today we ran into areas where there were many Juan Fernandez Petrel 
and Cook's Petrels just lingering around. Some of them could be called 
floeks. One of the flocks I saw was staying very low to the water. 
It was composed of Juan Fernandez Petrel and Cook's Petrels. They 
seldom get above the horizon. Because of the calm sea the Petrels are 
flying more like Wedgetails. They stay low to the water and more level. 
This afternoon a Skua came by the ship. It was lighter in color than 
the others I saw this trip. Later on Warren also saw a Pale-footed 
Shearwater and a solander's petrel. The white bill of the Pale-footed 
Shearwater showed up very plainly he said. 
October 1$ --The sea was moderate and choppy. The sky was cloudy to 
partly cloudy. Today we had more sightings than ever before. I added 
two new species to my life list. They were the Mottled Petrel and the 
Pale-footed Shearwater. The Mottled Petrel looked similar to a Cook's
