status of birds and mammals in areas farther off shore. This statement is based on the results of previous EAC Cruises during which it has been noted that coastal and pelagic bird populations are not similar in terms of specific composition, densities, and seasonal fluctuations. Plans call for the next two cruises to be in the same area, however no Smithsonian observer will be on board. The survey area of this cruise included three main regions (see map). However, due to an error in recording positions, no position in the area surveyed on 5 June is considered reliable within 25 miles. All other positions are reliable within five miles. Within each area there was considerable duplication of observations as the ship frequently went back and forth along the same transect line. No allowance has been made for this in any of the tables. Further complications in consistency of method also arose due to the frequent course-changes and speed changes throughout most of the survey. It is quite probable that at speeds exceeding ten knots the efficiency of observations declines and of course the resulting calculations would tend o be inaccurate relative to observations made at slow speeds. Jaegers and Skua One long-tailed Jaeger was seen off Santa Cruz Island. Three positively identified Skuas were seen in the same general area. Alcid Low numbers of Rhinoceros Auklets were recorded in the vicinity of the Channel Islands. Three sightings were of two birds together, and one was of a single bird. Three unidentified small alcids seen on the 8th were probably Cassin's Auklets. Marine Mammals Unidentified seals (probably sea lions) were seen commonly in waters off the Channel Islands. Sixteen Baird's Dolphin were seen off the Mexican - U.S. border and eres were seen southeast of San Clemente Island. Dall Porpoise were seen on three occasions in the vicinity of the Channel Islands. On one sighting three individuals were estimated to be travelling in excess of 20 knots. Two pods of Pilot Whales were seen during the survey. One group of about forty was seen heading southeast off the U.S. - Mexican border and another group of 20 was seen off San Nicolas Island. One unidentified whale was seen on 7 June.
