I have same question as Scubadoc. Which metering mode did you use. The EXIF didn't show the metering mode. Although the EXIF doesn't tell use that Auto ISO is on but you said it's on so it is. If the camera is in spot mode and the spot is on the bird then it's reasonable exposure otherwise it is not.
Check the menu b7: Fine Tune Optimal Exposure. This setting will bias the meter but only by maximum of 1 stop. Also this parameter doesn't get reset with the 2 buttons reset nor it shows on the EC.

Chg_Canon provided the right answer to this question. The minuscule fiddling with fine tuning, etc is besides the point. The unnecessarily stopped down aperture caused a high ISO. The critter was backlit causing the scene to be blown out since the metering was on the tiny brown bird. The bird is out of focus. And shooting BIFs is like hunting. You have to position yourself for the best possible angle of attack. A tiny brown bird against a cloudy sky (like a huge softbox) is nearly impossible to overcome.

He said he used the camera's meter for the exposure. Granted a slower speed and lower ISO might improve it, but that should wash as far as exposure is concerned.
I noticed the EC was at 0.

I have a new (to me) Nikon D850. I shoot birds mostly and I like auto ISO for the speed of gives me in adjustment. Even though the exposure indicator is balanced, my pictures mostly come out over exposed, which I have to fix later. Any ideas? I am using single point for focus - not sure that matters

That sounds like an exposure compensation is dialed up. Flying birds would be more likely to be underexposed because of the sky. Check and be sure you don't have any exposure compensation turned on.

The camera was trying to meter based on the AF spot -- and got it right. OP needs further education as to proper use of this sophisticated tool.

I always take the camera's EXIF, even a partial listing like the attachment, over any memories or theories of the human ...

Some of you may have more sophisticated equipment with different capabilities, but Nikon cameras meter based on the metering spot. The meter does not know or care about your AF spot.

Doesn’t Nikon have a way to set the metering spot to match the AF spot focus? Canon does, and I don’t think it is more sophisticated than Nikon.

I have never seen that in the manual or in any menu choice.

Thanks for the feedback on this. I was using different apertures to see the effect.
Lens was a Sigma 150-500. Couldn't get any closer. There was also no option to move the sun to a different side die to the water all around.
