Nice Shots !
The Nature Pro's use a strobe set up for shots like this ... set up off camera and remotely fired.
Allows better depth and also almost completely stops movement [except perhaps for the wing tips]
Sharpness is greatly improved and you get more detail as well.
One of my friends photographs birds and insects this way ... He does get some great shots but he does throw away a lot of them too.
