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 10,450 birds of 56 species were recorded. No nocturnal observations were made. The cruise 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'S, 92°W mainly along 92°W; Area E - 5°27'S, 92°W to Panama. By no means do these areas represent ecological or oceanographical zones. Instead they are merely small units which make the data easier to handle at the moment. TABLES 1-8 summarize the obser- varions for each one of these areas. FIGURES 2-21 show the distribution and abundance of several species
