    Comments: Saw a jaeger for about 2 minutes, mostly quite far away. It was chasing/harrassing a ring-billed gull for most of that time. The bird appears to be a light phase breeding adult. Although the photos are not definitive, most of the field marks that can be made out seem to point to Parasitic. These include: prolonged chasing behavior, deep & fairly fast wingbeats, wing base that appears narrower than Pomarine, extensive white on the underside primaries, "white flash" present in the primaries when viewed from above (rare on other jaegers) and contrasting black underwing compared to the primaries, unlike long-tailed which should appear a uniform gray on the underwing. I lost contact with it as it was flying across the reservoir and couldn't relocate it, although I remained in the area for an hour and then checked several other access points on the reservoir. Can't say with 100% certainty that it was a Parasitic, but seems most likely to me based on the scant photo evidence. Photos attached.
