ISO 800...in camera noise reduction was set to OFF. I had tried a couple of shots earlier with it ON, however it slowed down the shooting speed significantly.
There was no more processing required that I normally do. This took probably 2 minutes in NC to process.
I could have benefited by having another +0.3 or so...but it's tough to adjust that quickly when the birds are in really tight and swinging through so many different lighting situations. It;s much easier, for me at least, if they're further out and not 50' away.
