(1966) Bill Corey Journal Feb-13 Monterey Peninsula - 2 mi N of Town (Monterey) Cormorant observations from w rocky point. Day clear, bright, warm. A flock of 12 cormorants is seen offshore about 150 yds to the E. They are fishing on the shore side of the kelp which begins at this point. Their fishing behavior is thus: All birds are oriented in one direction, parallel to the line of kelp. The flock is quite close together, only 3 or 4 feet between birds. Simultaneously (within 5 seconds) all the birds dive. 2 dives are counted at about 37 seconds each. All the birds reappear at the surface some 20-25 feet from where they began, still together, and still oriented the same way. Presumably this is a method to drive the fish before the flock. Once after several dives in one direction, the flock puts up from the water and flies 30-40 yards back along the line of kelp to a point from which they had presumably begun earlier. However diving in both directions along the kelp was seen. These are Brandt cormorants. rocks kelp flock
