If your bird is blurry but the area just behind it is sharp, you might be dealing with back-focusing. Older DSLR cameras can sometimes focus slightly in front of or behind your subject due to a mismatch between the autofocus sensor and the image sensor, or a lens calibration issue.
Some cameras include AF Fine Tune (or Micro Adjustment) to help correct this and improve accuracy.
I explain more reasons you might be getting blurry bird photos in the full video. Link in the comments.
