The second multiple ship oceanographic survey of the Eastern 
Tropical Pacific Ocean (EASTR0PAC) was conducted during August and 
September 1967 • During this period I observed pelagic birds, mammals, 
and fish from the flying bridge of the Research Vessel Undaunted, of 
the Miami Bureau of Commercial Fisheries Lab, while the ship was ‘under¬ 
way. Generally, observations ceased when the ship was stopped for 
oceanographic station work. In coastal areas with the ship continually 
underway, I watched only eight hours a day. This preliminary report 
summarizes my observations. 
Diurnal observations were made for 359*1 hours while the ship traveled 
3>323*3 miles. During this time 10,U50 birds of 56 species were recorded. 
Ko nocturnal observations were made. 
The _ruise track (see FIGURE 1) has been divided into five areas to 
facilitate analysis: Area A- Panama to Acapulco along the coast; Area B- 
Acapulco to 5°S mainly along 105°W; Area C - 5°S 105°W to Salina Cruz mainly 
along 98 °W; Area D - Salina Cruz to 5°27 T 3, 92°W mainly along 92 C W; Area E - 
5 ° 2 , *3, 92°W to Panama. By no means do these areas represent ecological 
or ,je&nographical zones. Instead they are merely small ‘units which make 
the- uata easier to handle at the moment. TABLES 1-8 summarize the obser- 
v. ions for each one of these areas.
