What causes this haze, 600mm f4 lens?

If you use PS or Elements, try a Levels-Auto adjustment. My wife's Coolpix did that sometimes and the Levels adjustment cleared it up.

If the lens was inside and warm and you went outside the front element had condensation forming on it. So the first two shots had condensation. By the time you took the fourth or five shots the condensation evaporated. You should keep the lens in its case maybe put the lens outside for a few minutes before using it.
But these were not in order. No haze when I first went out. No haxe in between photos, only certain ones.

I had the same problem just last week with my Tamron 150-600. I could not see haze on the lens from condensation but it showed on the image.
I think it is atmospheric since photos in between were fine, it only happened occasionally. Can’t be condensation or it would have been consistent.

Look at my reply on Condensation. There was NO object in front of your lens. Condensation formed on it when you took it outside. This is a common occurrence when it is cooler outside.
Not thinking condensation or it would have been consistent. First shots were all fine, then hazy ones, then fine then hazy ones. The photos posted are not in order taken. Just showing that at times fine and at times not fine.

Photolady2014 in the first image you posted it is clearly obvious that your Canon EOS R5 grossly clipped all shadow detail and much of the mid-tones. I did a quick screen grab and dumped it into Photoshop...
Below is what your Canon EOS R5 recorded...
From the EXIF data: Manual exposure, 1/640 sec, f/4, ISO 500.
Seems that you are the problem NOT the camera nor the Lens.
Why? You choose rather inappropriate MANUAL exposure parameters.
Please go back out and let your Canon EOS R5 determine what it believes is the best exposure, k?
btw, I don't use Canon product so maybe other Canon users can better help you on your journey.
Oh, gvarner got it right: "try a Levels-Auto adjustment." Yep, thanks gvarner
The good news is your "Models" were wearing their very best feather down winter wear
All the best on your photographic journey Photolady2014

Initial Capture in Manual Exposure
(Download)
Shift to the Right Clipping of all Shadows and much of the Mid Tones
Levels Tweak to use only viable captured data
(Levels Tweak) Your MANUAL exposure lost the Lion's of shadow detail and much of mid-tones

My best guess would be the atmosphere between the lens and the subject. Every tiny spec of whatever will be cumulative and cloud the picture.
You can do a simple test to prove this. Take a long distance shot like you have done with the birds and then immediately after, take a shot of something closer at the minimum focusing distance of the lens. If there is no difference, atmospheric conditions are not the problem.

The fact that you mentioned it depended on where you aimed tells me atmospheric. Condensation would have been on all photos. Light bouncing off snow at a far distance can also play tricks. I think the slight overexposure may have been a factor to a lesser extent.

I don’t have an answer, but just keep experimenting and see whether it shows up again. Enjoy your new 600. For a wildlife photographer like you, it will become your go to lens!

It's the light reflecting off your white lens. :~)
I bet you're close. I think it's caused by some kind of reflection within the lens.

I really only see "haze" on the first 2. The rest seem fine.
That is exactly what the OP pointed out in her first post.

My bet is on the condensation theory (when you take a room temperature lens out in cold weather), as well as the fact that telephoto lenses compress distance and any fog/particles in the air magnified.

It could be, but the lens is so far out in front I don't think my breath would reach that far! I keep telling the husband I don't like photos of me.... but see how far out front it is!
You mention the front part of the lens but don't forget there is also the rear lens that is right by your mouth. Perhaps wear a mask when outside just to test if that is true or not.

I thought at first it might be the lens fogging when you first took it outside but then I saw that the first two hazy images were taken at 10:31 and 10:36, but the third image (not hazy) was taken at 10:25 so that is not likely the problem.
Don't know what you're processing with but LR enabled me to dehaze the jay photo a bit (dehaze slider all the way right). I expect it would do better with a raw file. PS with levels adjustment also shown. Quick efforts, not polished.
