Ya, the 1.4 added to the 400 might be clearer then just cropping the 400. Then you might compare that combo with a small crop to see which is better. I've got a 70-200 and sometimes use my 1.4. I don't do a lot of birds like you so never got a 400 or 100-400. You do get some great shots! (more cowbell!!)
edit...just realized you had tried the 1.4 on the 2nd shot..
