Take a closer look, you will see it’s not straight and not "laying exactly parallel to the rows of pixels".
And it’s entirely possible for it to be there for only one exposure.

Wow ! You’re quite the forensics expert !
Gotta agree that if it follows its own path ... not the pixel rows ... then it’s not likely to be a digital artifact.
Remarkably straight but not perfectly straight, weird but not impossible for a hair or a fiber.
One thing that bugged me when I was thinking it was an artifact was the way it ended before it went all the way across the frame, but I do see what you see ! So acoarst artifact is ruled out, and foreign object is in.
I wonder if it was not as long as it’s shadow but was shorter, fairly straight, and protruding offa the edge of the shutter blade set ? Then it would leave a shadow that traces the motion of the shutter ... til it fell off the blade causing the shadow to end abruptly before crossing fully across the frame ? That would also explain why it appears so remarkably straight but not actually following the bayer grid.
Oh well. Just the meandering of idle thoughts ...

An interesting idea....

I removed the lens & checked for anything on the sensor or mirror. There was nothing there.
Some additional info: In addition I had taken 2 more shots within a few minutes of this shot, one before & one after, same f stop. No artifact. Lens was not removed at any time. I appreciate everyone's suggestions, Thanks

Yup, lotsa that. I was thinking a segment of synthetic fiber, not curly, and the blades are plastic so a likely static charge makes it briefly cling ... etc.
Guess it’s a reminder to use HS burst as one’s default drive mode. Many things can ruin just one frame but leave the adjacent frames unharmed.

Thinking about your comment "Remarkably straight but not perfectly straight, weird but not impossible for a hair or a fiber.", I looked at it more closely and it did not look perfectly straight to me, BUT, I put it into PS and drew a line. It is perfectly straight (see new picture). But having said that, I think the only explanation is a perfectly straight hair or something, even though I did not see one when I examined the inside of camera. the other crop I attached is the area where the artifact disappears at the foot. Seems to just fade out, I don't think a hair would do that.

I haven’t read all the comments but I found it curious that the line didn’t continue above the bird.

Yesterday, upon the stair
I saw a man who wasn't there.
He wasn't there again today
Gee, I wish he'd go away!
If it is gone, I wouldn't worry about it.

likely something directly in front of sensor, hair, bristle, similar.

I'd go with this explanation. Depends how and when your sensor was last cleaned, I have a sensor cleaning brush that is "charged" to attract dust and it is synthetic and bristles are very straight. The action of triggering an exposure would be enough to move it around inside the camera so as to be there one shot and not the next. Check inside the whole area mirror, sensor area as it could still be lurking to catch you out. It cannot be a digital artifact or Photoshop else it would be more consistent in my view. Fading out near the birds foot if that's the tip of the fibre then it would look exactly like it does in your crop of the image.

Looks to me like you caught the tail end (pun intended) of a turbo-poop. Seriously though, not sure what could cause a straight line anomaly like that.

Maybe your eagle crapped and it streamed down your photograph as it was being exposed. Just a thought.
