I suppose another way of framing the question: let's imagine a bird, about 15cm tall - with a 600mm lens, what would be the closest and furthest away this could be for a sharp and interesting portrayal? How big is the range you have to work with?

At 6m, you would have a very tight (landscape oriented) framing 24cm high. At 12m = 48cm, which might be too much without cropping. Of course, with a good lens, you can always crop, so 15-20m is pushing it.

BTW, it is not trivial to frame you bird with a long lens if it is moving. You have to keep both eyes open and literally hunt.
