Dear Bob: 
Enclosed are the data you requested. I included all the SIC cruises 
from 1 to 165 although the data for the first 8 are rough and not continuous. 
I broke numbers down so that you can subtract direct migrants e.g.. Sooty 
and Slender-billed Shearwaters, Mottled Petrel, shorebirds excluding 
phalaropes. White-eye, and are left with those birds which are interested 
in that part of the ocean as a food source, which will probably show a clearer 
correlation with oceanographic conditions. In those few instances where 
Sooty or Slender-bills were observed feeding they were tallied in the flock 
data. Otherwise flock data refer to feeders or potential feeders, or in 
other words, birds which feed in the central Pacific and were seen in flocks, 
not necessarily feeding flocks. 
It would have taken too long to determine mileages for each half day. 
In most cases I have provided sunrise to sunset mileage and if you choose 
you can figure a proportionate distance based on length of observations in 
morning and afternoon, 
hours observed in morning _ miles travelled in morning 
total diurnal hours total diurnal miles 
or something of the sort. Hours of observation should be sufficient to 
give you rates. I omitted almost all grid observations since they will be 
covered elsewhere in the April report. Let me know if you need anything else. 
The conversion of the ADP System to the IBM 36O has just about been completed 
and we*11 begin to purge sighting data of error sometime this week. 
Sincerely yours.
