Not really. It is a technology and light thing. For example Canon FF sensors set to stops higher iso will not raise shadows as well, and neither will a Sony.

So as I said, if your ff shooter is at f11 and ISO 1600, you will be at f5.6 and ISO 400. Both Sony and Canon do not have a full two stop noise advantage and will have noisier shadows. In Sony's favor they have a lot of high resolution bodies to claw back some of the noise.

Nikon is really the class leader here, but even they are not miles ahead of the 2 stop difference.

So, sure if the FF Camera uses a larger aperture and the same iso three is lots of advantage, if they use the same size aperture and a higher iso they don't, especially not a Canon.

The thing is if you are shooting birds in flight DOF is not a challenge even with long telephoto lenses on FF . Unless the bird is a pterodactyl . Thanks to the distances typically involved { hence why you are using long telephoto lenses} . Plus shooting birds is bloody hard in the daylight so I doubt many are doing it in the dark

Doesn't have to be in the dark, many shoot when the light is less than a sunny day at noon.

If you can sneak up on the wee buggers you can then shoot with shorter focal lengths . People here tend to forget that before digital came along 35mm was considered a small deep DOF format relative to other systems . While 110 film was of course a low quality toy format

Then there is of course the huge MP count available on many FF cameras such as the 45mp D850 or 42mp A7RII/III. Which allows for significant cropping whilst still retaining a large file size if really needed .There is also a far lower penalty for pushing shadows on for example a BIF shot , where the far brighter background typically results in a somewhat underexposed bird unless you choose to blow out the sky.

Again, the noise penalty exists for the same exposure settings. SO yes, shoot at F2.8 ISO 200 on both formats there will be a significant file advantage. But not if the FF user is at F5.6 and the m43rds user at f2.8

Here is a 19.4mp crop from a D850 which gives you a 1.5x crop factor

Very nice, of course more MP works, and I wouldn't mind a 42mp sensor made with the current 1" tech.

I would agree, that is one sharp logo. Would you have preferred a bit deeper focus so his face was as sharp as his logo?
