If you're always cropping your shots a lot, subject differentiation and nice blurred backgrounds are a function of the size of your lens aperture, not the size of the sensor. If the distances are the same and the focal length and aperture are constant, the geometry doesn't change, so the subject differentiation and background blur won't change, whatever the crop. You need a bigger aperture (in mm, not f/ number) to improve those things.

A bigger aperture only makes a difference if the sensor fully uses the projected image circle. Putting FF glass with a big aperture in front of a crop sensor won't help, unless you put a focal length reducer between the lens and the camera. But then you lose a lot of the extra reach the crop sensor provides, as well as some light in the optical path due to the extra glass.

If the OP wants blurrier backgrounds behind the birds, he needs a hide and some camo clothing, not an R7.

How the heck did I end up with this username?
