NON-GRID SURVEY The non-grid phase of this cruise includes parts of three days of observations. Two periods were between Long Beach and point "A" of the grid, while one day was spent between point "H" and Long Beach. Both tracks were essentially the same as on previous trips. On previous Eastern Area Cruises the non-grid portion has been analysed from the standpoint of the two cruise tracks. In this survey report an alternate treatment seems more meaningful. Instead of dividing by cruise track, this phase of the report is divided into those observations to seaward of the Channel Islands and those observations inside of the islands (see map 2). It is felt that this treatment is more meaningful when compared to the grid observations. Flocking in the non-grid areas of this survey was a significant activity, especially in areas near Cortez and Turner Banks off San Clemente Island. This behavior will be discussed in the species accounts. NON-GRID SPECIES ACCOUNTS Loons As none of the loons seen were well observed,no specific identifications were possible. All sightings were of migrants travel- ing north inside the Channel Islands. Albatross All but one of the fifteen black-footed Albatross seen were outside the islands. Two Laysan Albatross were seen near Cortez Banks. Shearwaters/Petrels The only Fulmar sighting for the trip was a single bird near
