Beautiful evening!

I need the help of experienced R5 users, please! My R5`s AF fails, when I want to shoot birds that are not format-filling. The AF always focusses on infinity and stays there, even if the selected AF field (spot AF, extended spot AF) is pointing sufficiently on the bird. The subject meets all needs on contrast and size to cover the whole AF-points. To solve this problem, I´ve to rearrange and point the AF field on much nearer object, then it focusses correctly in most cases.
But this is not satisfacting. These days I lost a lot of shots, when an kingfisher fetched fishes mnultiple times out of the water.

Any advide to solve this background fixation?
Thank you!

How did you hold the camera? Upright or horizontal?
horizontal.

But the bird had a lot of horizontal, vertical and diagonal structures. The 5D Makr IV did not have any problems with Single AF and spot AF. I tried it too.
Maybe there is an Af setting, I did not change... I´ve also tried a lot changes at AF and resetted it at the end

It's a problem with Nikon, Sony and now Canon mirrorless that they don't give closest subject priority so often they will focus on background. I have found that sometimes annoying with the R5, but not to the extent you seem to have but I generally use eyeAF, which seem to recognise eyes quickly.

Yes, I had a similar issue with the RP a few months earlier...very frustrating to be honest as my 5D bodies don't do this. it's a mirrorless issue I think. Still maturing...

DSLRs aren't dead just yet ;)

Could you share your current AF settings? And what different things you've tried with the settings? How is it doing with stationary subjects at various distances? Is it happening with more than one lens? How does it work with subjects on the ground but moving somewhat quickly?

Hope it's just a familiarity issue for you!

I have reprogramed the "*" button to be a single point AF. Whenever I am having issues with AF, I switch to the "*" button, aim at target, and then I switch back to AF-On which is set to eye-AF. By getting the subject is good initial focus, the Eye-AF can then take over.

Similarly here. For my C1 mode for static or slow moving subjects the shutter button activates single point AF and the AF-On button overrides that to animal eyeAF. I would like to have it the other way round as well but you can't do it so clearly. You can set the shutter button to activate eyeAF but I couldn't find out how to asssign another button to single point AF, only to set it to start at the centre.

Myself I have setup the R5 with back button focus, one button for autofocus (af-on)z, and the other (*) button for eye detection.
I have not had many issues with birds inflight or statics, but there are times that my lens will lose the subject and won't refocus without manually turning the focusing ring on the 600 IS II lens. I also think autofocus was a bit better before the 1.1.1 firmware at least for the 600mm.

Thank you all!
Sorry for late answering, I had some hardware issues with my computer
I am trying a lot to customize the settings and find the best solution. But the AF still struggles.
Next, the AF single, switched to automatic AF with all fields will be tested.

AF method: :)[]
Motives: animals
Eyedetection activated
AF case 4
kontinuos AF

As an example, the approachin redkite was never detected by the AF in this setting, even when it wasfilling half of the sreen. Pressing the AF button sveral times did not change the AF-point and refocus.

The same in single spot AF:
Focussing on the kingfisher was not possible. Always the AF went back to the background. Only, when I manually refocussed on an near bush, the AF point found the bird.
