Yes, I have tried it and also have eye detect on as well. I have a second button to switch to between single point and this setting. But often with small birds the auto-focus jumps around and grabs something else.
In AF menu 5, make sure the top item (Initial AF pt set for...) is selected. This will put a little box in the middle of the screen and that is where eye AF will focus its attention. Once it has grabbed focus, you can move the camera around to recompose and the AF will stay on whatever it originally found.
You can also move the initial AF box around using the touchscreen or the joystick, but I leave it in the middle and then recompose.
PS: I have no idea why this item is in menu 5.
