觀察細節

🔴RARE & LIFER! Possibly two. Buoyant flight like a tern. Dark underwing lacking white-wing patches. Seemed more gray than brown overall. Long thin wings. Note only the 2 white primary shafts on the outerwing - unique to long tailed jaeger (see zoomed in photo) Bold and well defined barring on undertail coverts (visible in some pics) It came in from Jaeger rocks along Canadian shore. I first got on it about 1/4 mile out past the point. Came zipping down river. Seemed smaller and much faster wing beats than the parasitic. Only maybe 25-30% bigger than a BOGU. Close to the size of a Ring Billed gull, maybe even a bit smaller. It turned at the peace bridge and worked slowly upstream giving great looks for about ten minutes, often times landing on the river and just floating downstream. Then periodically would cruise by and do it again. Chased BOGU a few times and COTE at least once. Lot of people saw it and great pics of it. Never saw two at once.
