When skies are overcast and light is wretchedly poor, one can not see "birders" outside practicing their craft even on stationary targets, let alone on BIF.
Under such poor ambient light conditions, any f/5.6 telephoto lens is hopeless, such as 400 f/5.6, let alone 800 f/5.6.
With f/4 lenses, e.g., 500 f/4 or 300 f/4, one is relying on lucky shots.
Lastly, 300 f/2.8 IS and 400 f/2.8 IS become just marginal.
What telephoto lenses are then left which can cut it ?
Well, there are only two of some practical application: 200 f/1.8 and 200 f/2.
(135L is a great low light performer too, but way too short.)
Although 200 f/1.8 can "see" dark objects well enough, unfortunately it doesn't have a very fast AF drive, which really leaves us with 200 f/2 IS.
Although I do consider 200 f/2.0 IS overpriced, the lens is a very solid/dependable all around performer, in just about any shooting conditions.
Therefore, when low light makes outdoor photography ridden with problems, if not impractical, I take my 1DMkIIN + 200 f/2 IS and go shooting pijuns in flight, if they are inclined to fly, that is. In my books, that is more fun than sitting in front of the computer and talking about things such as a rumoured 5DMkIII sensor size and some such.
The images below were all shot as JPG only, using 1DMkIIN + 200 f/2.0 IS wide open, IS turned off.
Servo AF mode, center AF point with auto expansion.
Manual exposure mode.
