The battery of the D7k drives the focus on the 80-400 lens. Even with this combination the battery still lasts for more than a 1000 shots. The 80-400 is a slow focusing lens and therefor you need to be ahead of it. I have found the combination to be very good for Aviation but not sure about hand held for birds but would focus faster than a D90 or D50. On the tripod, I get shots of the moon that I could not get very well before the D7k with the 80-400.
