Joshua,
First, this is a gorgeous little bird!
Second, Ditto Randy.
Third, in a perfect world part of the perch (in the lower left corner), would not be an OOF broken limb.
Good suggestions above. I might have gone with f/7.1 or f/8 at the most; it would have softened the BG a bit more while still giving you enough DOF to get the entire bird in focus.
