Thanks, I will have to try the four corner or brick wall test.

Not sure if this pic I took wide open with the TC looks like the normal quality and sharpness of a good lens or not, but maybe hard to tell from bird pics rather than proper tests.

The TC difference with vs with TC is rather pronounced when scrutinised at 100%. So if you wana know whether your lens is fine, you'll have to test without. Also, birds move, light and atmosphere vary a lot, so, well, your lens is probably not blind:-)

The usual way is to do a four corner comparison, see various variants of the same test idea:
