    The wingbeats of a "young Herring Gull" approaching low from the northwest identified it as a potential jaeger. As the stocky dark jaeger passed by, the jaeger wing shape and the under-wing white flash were obvious. Upper wing white primary shafts were visible. The jaeger continued directly toward the largest gull flock having the largest number of young Herring Gulls as well as many Ring-billed and Bonaparte's Gulls and a few Great Black-backed Gulls all participating in a feeding-frenzy above some Common Loons.

    While the jaeger was successfully obtaining lunch from each of three juvenile Herring Gulls, it provided an excellent direct close comparison of its large size, stocky proportions and wide broad-based wings to those of the Herring Gulls, confirming my initial identification of it as a Pomarine Jaeger.

    The distance, the atmospheric conditions, and the rapid flight precluded any thoughts of checking all fine details such as the extent of barring; my priority was simply to enjoy the flight display. However while the Pomarine was attacking the young Herring Gulls, chasing them higher above the water, I twice did take notice of the broad short tail with its slightly rounded central tail feathers — rounded feathers typical of juvenile Pomarine Jaegers — unlike the pointed feathers of young Parasitic Jaegers.

    After the Pomarine's third drop onto the water to pick up food, it continued south-bound.
