f7.1-f9 is the sharpest part of the 55-250. I would also edit the incamera sharpening of the jpegs. It looks like you are shooting natural, you can increase the camera processing to sharpen more.

That is your problem. your subject is too far away for the lens you're using. You're just not going to get good results. For a bird that size, with that lens you would want to be within 2 meters of the subject, not 20. Capturing small birds is challenging and requires quite a bit of focal length AND the ability to get close. When you shoot from too far away you're just not going to get good focus accuracy AND you're not going to capture enough fine detail for you to be able to crop and have a decent image. If the subject were child size then you could get a decent image at 20 meters with that lens.

You can only crop about 25 precent, after that it loses to much resolution.

wont work with the lens you have, the 55-250 was not design to work with a TC.

I would steer clear of a TC altogether unless you have something that is at least 2.8. You will most likely otherwise get the same results you got only closer and with less cropping. It gives you more reach but the overall quality will suffer most often than not.
