Are you talking about the loss of color
If it is, there is nothing you nor your camera can do about it. It is what happens when bright light passes through a slit or such gap in a dark foreground barrier. the smaller the opening, the greater the diffraction.
At least that is what I remember from my physics courses 40 years ago
It appears to be unavoidable conditional CA. It's not just the slits but also the high contrast outlines. I see it in plenty of shot here so I'm not the only suffering it. If it was a different color it would be easily fixed but it's a bright almost colorless outline that is hopeless to get rid off. I even tried changing the individual color channels to see if that does something but it is persistent.
It's one of those things that once your eye sees it, it drives you mad.

To me it REALLY looks mostly like sharpening artifact around the perimeter, not CA , for CA you really should be seeing color abnormality.
IF you use unsharp mask , you can either reduce your radius to mAYBE .5-1.0 pixel at 190 power , or you can use 3 pixels at 25 power, which works better depends on your background and how tight you had to crop.
You can also get a lightening effect as shown between the primaries like that if you use any of several post processing means of lightening shadows or reducing highlights . Feathers may have a translucent worn edge that can catch the light but on the crow , Im not thinking its that.
I'm assuming Youre seeing this on JPEGS but not on unmodified RAW pix? But beware that your eyes can play tricks on you and you might see the effect a little even when its not there, zoom way in tight to 200% or so and you can see if its just not your eyes sometimes - though the ones here dont appear to be that.
( an overall color temperature adj to get rid of the CA wouldnt seem a likely fix -sometimes they call the lateral CA a color 'noise" and you do have a teenie tiny bit of that --no pix are really perfect.)
Oh, and a teenie amt of blur can add colors to the blue which then shows as a gray where really really zoomed in.
