disturbance - 8:03 eagle (Sm) Birds moved out 60 yards then moved back to about 40 yards

disturbance - 8:39 eagle (N)

disturbance - 8:52 eagle (Med) Birds out 60 Yards

disturbance - 8:54 eagle (End) As we left we noted an eagle perched above bluff in tree so that is probably the reason for no visits to burrows in south bluff. Eagle effect on birds is alarming.

disturbance - 8:03 eagle (Sm) Eagle stayed in tree during entire visit, but birds moved back close to shore and even onto exposed rock.

disturbance - 8:05 eagle (N) 8 to 14 birds were close to shore and came up on the beach. These birds stayed close to shore through most of visit. It seems that most of the birds that come in with food come from a long ways from shore with the prey while those close to shore don't have food to deliver. Perhaps food is caught in deeper water.

disturbance - 8:14 unknown (Sm) Birds seemed agitated, but no reason was apparent. They were flying to burrows, buttons were carrying food. Tide was way out so maybe they felt uncomfortable with so much of beach exposed and water so far away.

disturbance - 8:00 unknown (Lg) This was somewhat a repeat of what we saw 7/11/18 with the birds on the move or perching on the bluffs so counts were hard to do. Most did not spend much time on the water and there was only one that took prey to a burrow. No other birds were seen carrying prey during the entire visit.

disturbance - 8:44 eagle (N) Birds did not seem to react although eagle flew over the water. They began to come back closer to shore so perhaps the eagle had been in the trees above the bluff out of sight of the observers.
