Well, Conrad, proximity to your target beats FL any time, and that includes 500, 600 and 800 lenses. Here is another tern caught with a 200mm lens.
In fact, on these kinds of birds I get the best results with the following lenses: 300 f/4 non-IS, 300 f/2.8 IS and 200\'s (f/1.8, f/2.0 and f/2.8 primes).
The 400 f/5.6 is good but often too long and too slow......larger aperture lenses allow faster/more accurate focusing which is more critical here than FL.
