Hmmm... I'll have to dive deeper into my menus because I actually can't refute that I guess I should spend some more time birding with my D7K.

Really my question is about which of my 2 existing cameras do I keep. I've never been a fan of the 12MP FX cameras for birding, as I believe they just push you to much bigger and more expensive lenses, but that's a completely different argument and one that's well-worn already.
Thanks for your answers, you definitely gave me some things to think about.
