Hi All: Went looking for jaegers associated with Bonaparte's gulls near Point Defiance (Dalco Overlook). Watched two juvy Sabine's gulls flying about in the flock of about 400 Bonaparte's for 40 mins. I got there at 12:30, tide was incoming with a strong current that the Bonaparte's were feeding in by flying up current and drifting down. The Sabine's were flying around foraging and not doing the drift feeding - they were really obvious from above on the bluff.
Only saw one parasitic jaeger.
