We steamed a fixed course of 080° ell day today, directly into a 
wind from the east, giving an effective wind velocity of 20-25 knots. The 
weather was cooler, largely due to the wind, and the sky was overcast much 
of the day, with scattered squalls. 
We recorded from sunrise to sunset only today, and this will he 
the plan for the remainder of the trip. Night observations are not 
stat istically valid as they prove only one thing—that certain species are 
active at night. A' we are limited in visibility to the short range of 
our lights and the chance straying of birds into their beams there is no way 
of deriving from this nighttime data any valid census of total bird activity 
et night, ?s we are able to do in the daytime with mush more thorough censusing
