Blaster34, I think their use might be limited. Much like a rifle sight, they would have to be adjusted to a preset distance in order for the bird to be exactly where one wants it in the field of view of the lens when the dot is on the bird. Sure a little bit off might still work, but with telephoto lenses, the field of view is pretty narrow.

Thanks Bob, surely understand that and calibration of the sight to the focal point of the camera would have to be done each time it is either removed/installed and used. I was wondering if the subject is anywhere within the focal area, the A/F would pick it up. Looking 'through' a reflex sight seems to be an easier way to try and follow birds than through the OVF (limited viewing). For me, using my rifles and handguns with a holographic/reflex sight is much easier than looking through a narrow fov of a scope. And I also know it takes practice, practice, practice...
