观察细节
Still present. We were waiting at the pinned location for about an hour before a number of gulls and a few terns came from the ag field to land in the water. About 5 minutes later, a commotion arose among the flock and we could see that the PAJA had targeted one RBGU to chase. The PAJA successfully forced the gull to yield its food, then the PAJA went back to the ag field briefly. It did another pass over us within several minutes, but did not successfully harass a gull that time. It then went to the far edge of the field. After about 30 more minutes, we saw a group of gulls rising about 1/2 mile off to the west, but we were unable to determine if the PAJA caused that activity.
