Деталі спостереження
Dark morph juvenile first found earlier this morning by Aaron Batterbee. Medium sized all-dark jaeger with light cinnamon barring on underparts and neck. Seen fairly well although briefly at very close range while it was harassing gulls. Long-tailed Jaeger eliminated by the 5+ white primary shafts on the wing upperside, as opposed to only two in Long-tailed (fide Kaufman, 1990), as well as a bulkier appearance than expected for that species. Pomarine was more difficult to eliminate definitively, but the thin bill with little hint of a gonydeal angle, fairly small head, slightly paler nape, as well as the smaller size and seeming more slender and agile than expected for Pomarine and certainly from what I remember from a previous sighting of that species. Unfortunately was not able get a great look at the central tail feathers, so was unable to use that as an identification aid. Photos by Andrew Miller
