1. Birds and other animals observed in the study area and their ADP 

 numerical equivalents 109 



2. Dally data summaries. Identification is the ADP-coded species 

 name. Quantity is the total number of birds of a species seen in a 

 day; incidents are the number of sightings of that species in a day. 

 Noon location is expressed in octant, degrees and minutes latitude, 

 degrees and minutes longitude. Octant 1 is the area within lat. 0° to 

 90° N. and long. 90° W. to 180°. The initial digit of longitudes 100° 

 or greater is omitted; hence if longitude is 5740, read 157°40'. Hours 

 are the duration of observations; miles are the nautical miles trav- 

 eled during observations. Ship 6 is the Townsend Cromwell 111
