Confusing the issue more, I was out at The Wash soon after (30 min?) the
jaeger was reported in the river, I think I was walking in from one way as
Aaron was walking out the other, in any case, I did not see the Long-tailed
in the river, however I did see the Parasitic Jaeger standing out on the
mudflats near one of those logs. So both have been present in very close
proximity of each other out there.

Hi all,
I agree these are different birds. The bird that I photographed in river
leading out to the Wash on the 8th appears to have been a juvenile LT
Jaeger. Likely it is the same bird reported by Andy today. Most of the
features listed by Russ (very useful by the way) fit the bird in my photos
e.g. the clean black-white undertail barring, round head, shorter bill, and
the crisp whitish barring on upperside. No one has noted behavior so far
but the flight style of the bird I saw was rather languid with shallow-ish
wing beats, a bit reminiscent of a nighthawk.
All that said, I’m still perplexed by the amount of white on the primaries
in my photos. Also, to my eyes the bill isn’t quite "at least half black”
i.e. reference sibleys.
Fascinating topic, valuable question David!

Nicholas, I agree that the bird in flight in the ebird checklist you
posted (Audrey Adisson's checlist)is Parsitic, as is the standing bird
pasted in the upper left of the photo you attached. I think the bottom bird
of your attached photo is likely a Long-tailed. I agree with your points
about buff colorations.

All,
Here’s a side by side of the Jaeger photographed yesterday by Peyton Cook
(bottom), and the one I saw a few days ago in Columbia County (top). It
seems pretty obvious these are two different birds, and thanks for starting
the conversation David.
For the record, the upper bird had a noticeable gold-buff nape, and
lacked the scalloped look that this other Jaeger shows. It was roughly the
same size as a Ring-billed Gull. Here are some more photos of the first
bird, from Audrey Addison (whom I hope doesn’t mind me sharing the link!).
You can see the feather edging is less prominent and more buff colored on
the dorsal side of this individual.

David makes some good points. I'm not at all sure this bird is the same
jaeger as the one sighted late last week. I wondered about this the first
time I saw photos of the bird hanging out in the vicinity of the Oak Island
boat ramp yesterday. The photos I've seen of the current bird give the
appearance of a darker, daintier bird than the one observed late last
week. Attached are two checklists of last week's bird, which I feel more
confident is/was a Parasitic Jaeger.

There are more photos of both birds floating out there on ebird for
comparison. This is a great education in jaegers for us non-coastal types.
Good birding,

Andy and obol,
Great pictures.
I struggle with juvenile jaegers, but the bird from your photos (
https://andyfrank.blogspot.com/ ;) looks much like the bird I found on
the beach in Clatsop County a few years ago (see here:
https://www.flickr.com/photos/49113196@N05/ ;) that many of us were
satisfied calling a Long-tailed Jaeger.
Sibley notes small bill with a nail half the length of the bill, and
white (not buff) feather edgings for Long-tialed juvenile.
I would like to see discussion on the identification of this jaeger.
Feel free to discuss the bird I photographed too.
Humbled,

Seen this morning at same location as yesterday, about 0.5 miles north
of the Oak Island boat launch. This is in Multnomah County.
Most of the time it was walking around on the mud pecking at it. At
one point it harassed a Greater Yellowlegs. After I had walked part way
to
it, it flew past me in the direction of the boat launch and landed on the
mud, requiring me to walk by it on my way back. It allowed a surprisingly
close approach before flying north again.
